Twin Taung Hill
An extinct volcano whose crater now forms a beautiful lake. The surrounding area has lush vegetation, and there are lovely views of the area from the rim of this crater lake. The lakes Algae is used in the production of vitamin E so I've been told hence the work signs at the Burmese production plant.
Algae acquire vitamin B12 through a symbiotic relationship with bacteria.
The Lower Chindwin is an area of around seven or eight explosion craters, located some 30 km (20 mi) northwest of the town of Monywa in the Sagaing Region, Burma (Myanmar).
The volcanoes originate from the late Pliocene and Pleistocene times. The craters are dormant (Smithsonian volcano number = 275090). In the Global Volcanism Program of the Smithsonian Institution[1] no information on Holocene eruptions, dating back 10,000 years, is listed.
The major rock types of the group are Basalt, Rhyolite, Dacite and Andesite.
Three to four craters have lakes, one of which is east of the Chindwin river, the others are to the west. The eastern lake is named Twin Taung (or Twindaung), the others Taung Pyauk, Twyn Ma and Yay Khar. In the lakes the cyanobacteria Spirulina (often called blue-green algae) grows. It is harvested, dried and sold as medicine. At the end of 2014 it was reported that the Government of Myanmar planned to nominate Twin Taung Lake for inclusion on the list of UNESCO World Heritage Sites.

Extended Abstract
The Monywa copper deposits are west of the Chindwin
River flood plain, 115 km WNW of Mandalay. There are four
deposits (Fig. 1), Sabetaung where open pit production
began in 1983, Sabetaung South also in production, the
larger Kyisintaung deposit immediately W of Sabetaung,
and Letpadaung, by far the largest, 7 km SE of Sabetaung.
Copper resources at Monywa prior to mining totaled around
2 billion tonnes ore with over 7 million tonnes contained
copper, making Monywa the second largest copper deposit
in SE Asia. This account of the geology, based mostly on
recent pit mapping, is the first published description since
that by Kyaw Winn and D.J. Kirwin, and the start of large-
scale mining, in 1998.
The deposits lie within the Central Basin of western Myanmar
(Fig. 2) on the eastern flank of the Wuntho-Popa magmatic
arc, a 460 km-long geanticlinal uplift which is the northern
continuation of the Sunda arc. The uplift exposes Upper
Cretaceous granodioritic plutons intrusive into pillow ba-
salts, diabase and gabbro and minor gneiss, and Cenozoic
calc-alkaline intrusions and eruptive rocks. To the W are
the Chindwin – Minbu sub-basins with their 10 km thick
succession of Albian to Pliocene sedimentary rocks, and
to the E the largely Neogene succession which occupies
the Shwebo sub-basin. The Indo-Burman Ranges, W of
the basins, consist of two belts separated by an E-dipping thrust. In the Eastern belt, up to 3188 m elevation, Upper
Triassic flysch and ophiolitic rocks overlie mica schist. In the Western belt, a sequence of highly deformed Senonian
pelagic limestones, mudstones and turbidite sandstones are overlain by Paleocene and younger clastics which pass
westwards into the Chittagong – Tripura fold belt. Most of western Myanmar and the fold belt are moving northwards
on the Burma plate, bounded in the W and N by a subduction zone and in the E by the Sagaing Fault.
Mineralization at Monywa is hosted by dykes and sills of porphyritic biotite andesite, quartz andesite and minor dacite,
by minor rhyolite dykes, and by the folded Upper Pegu Group (Fig. 1) which the volcanic rocks intrude. The mineral-
ized sequence, of late Miocene age, overlies Mesozoic rocks of the Wuntho-Popa arc, and consists of sandstones
and shales, overlain by more than 300 m of late Miocene andesitic pyroclastics, possibly including diatreme apron
deposits. The pyroclastics are cross-bedded and include abundant clasts of silicified and phyllic-altered andesite
porphyry, quartz-pyrite rock and pyrite. Sabetaung South pit is mostly in sandstone, Sabetaung in pyroclastics and
andesite porphyry intrusions, Kyisintaung in andesite porphyry, and Hydrothermal alteration assemblages in mineral-
ized rocks are predominantly advanced argillic consisting of replacement quartz together with alunite, pyrophyllite,
and minor diaspore, kaolinite or dickite, accompanied by pyrite and indicative of acid sulphate fluids and rock-fluid

reactions at epithermal depths down to 2 km. At Sabetaung South the mineralized sandstone is mostly altered to
quartz-sericite-pyrite; at Sabetaung, alteration includes two bodies of copper-poor texture-destroyed quartz-pyrite-
alunite within alunite and sericite-bearing assemblages. Around the deposits andesite porphyry is variably chloritised
with quartz-calcite-pyrite veinlets, to more than 200 m depth.
Mineralization extends downwards from the base of oxidation, near the water table mostly between 70 and 120 m
above sea level, through a vertical interval which at Letpadaung locally exceeds 540 m. The predominant copper
sulphides are chalcocite and digenite, with subordinate covellite, invariably accompanied by pyrite. Enargite, rarely
seen in the pits, is reported in petrographic studies from all the deposits. Chalcopyrite and bornite occur as inclusions
in pyrite. Most chalcocite is crystalline, either massive or
coating pyrite, but black sooty chalcocite also occurs at
all elevations. Among the few assays for additional metals,
28 samples from Kyisintaung drill core averaged 0.15 ppm
Au, 23 ppm Ag, 85 ppm As, 18 ppm Mo, 12 ppm Co and
0.18% Ba, together with 0.59% Cu.
Mineralization (Fig. 3) in the pits and in Kyisintaung and
Letpadaung drill core occurs in breccia dykes, in thick
shallow veins, in spaced stockwork veins, sheeted veins,
and through-going shallow-dipping veins, and as dissemi-
nations. Breccia dykes and steep veins mostly trend NE,
but NW strikes predominate in Sabetaung South. Breccia
dykes are a prominent feature, most are steeply-dipping
bodies with parallel margins, but a few splay upwards
or follow low-angle structures. They are clast-supported
with angular fragments of wall rock, and rounded clasts
of andesite porphyry and rarely massive chalcocite. Brec-
cia dyke widths in the pits are mostly less than 1 m, and
decrease with depth, but some at Letpadaung are more
than 10 m wide.
Unmineralized breccia dykes have a mud matrix. In min-
eralized breccia dykes or hydrothermal breccias, chal-
cocite and covellite occur as matrix together with pyrite
and replacement quartz, usually with alunite in vugs and
sometimes accompanied by coarse euhedal barite. Veins
of chalcocite-pyrite, chalcocite-covellite-pyrite or massive
pyrite are common within the dykes.
Veins are planar structures and include sulphide-coated
fractures. The thick shallow veins are mostly steeply-dip-
ping and up to a few metres wide but narrow downwards
and some disappear within 10 to 30 m of the mineralization
surface. Spaced stockwork veins are up to 20 cm wide
and tens of cm apart. Through-going shallow-dipping
veins can persist for over 50 m and are mostly less than
10 cm wide. Sheeted veins are close-spaced vertical or
steeply-dipping cm wide structures, largely confined to
a 130 m wide NE-trending zone in Sabetaung. Although
visually impressive, sheeted veins do not everywhere
carry significant grade. Throughout the pits, most veins

cut breccia dykes. Disseminated chalcocite coats pyrite
grains and is most common at shallow depths. It also
occurs throughout the Sabetaung high-grade zone, a
vertical carrot-shaped body up to 30 m wide. Its upper
levels contain up to 30 percent Cu and include massive
chalcocite. Below, disseminated chalcocite replaces
plagioclase phenocrysts but is locally leached, leaving a
porous framework of replacement quartz; breccia dykes
are cut by planar veins of crystalline chalcocite and soft
black amorphous chalcocite.
A latest Miocene age for the mineralization is implied by
a K/Ar age of 5.8 Ma on an andesite porphyry dyke SW
of Kyisintaung. We consider this and other unaltered or
chloritised dykes to be immediately pre-mineral but distal
to mineralization. Early to middle Miocene K/Ar ages on
hydrothermal minerals are not easily reconciled with the
inferred late Miocene stratigraphic age of host rocks.
The Kyisintaung and Letpadaung deposits are overlain by
spectacular barren leached caps locally more than 200 m
thick and forming hills rising to 185 and 240 m above the

plain (Fig. 3). During prolonged regional uplift, and consequent fall of the water table, mineralized rock was exhumed
and oxidized; acid water from oxidation of the abundant residual pyrite leached copper and re-deposited it as super-
gene chalcocite below the water table where it replaced pyrite. The descending acid water also resulted in argillisation
to depths of 50 to 100 m below the base of oxidation. Possibly around 75% of the copper in the upper levels of the
deposits is supergene chalcocite-digenite, a product of continuous re-cycling and progressive enrichment.
In the NE part of the Sabetaung and Sabetaung South pits mineralization and locally leached cap are overlain by
super-mature gravels and strongly cross-bedded sands (Fig. 3), possibly the basal part of the regionally widespread
late Pliocene-Quaternary Upper Irrawaddian (Fig. 1). The sands around the deposits are a potential environment for
exotic copper derived from the oxidizing surface of the enrichment zone.
The Monywa deposits, first drilled in 1957, were interpreted by a Japanese team in 1973 as epithermal and analogous
to their “Nansatsu-type massive sulphide” (high sulphidation) gold deposits; they were re-interpreted as supergene-
enriched porphyry copper deposits by a United Nations-supported project and R.H. Sillitoe (in United Nations 1978),
and finally re-identified as high sulphidation by D.J. Kirwin in 1995 and by feasibility study consultants in 1996.
Mineralization can be explained by condensation in meteoric water of magmatic SO2 gas ascending from crystallizing
melt at the roots of the andesite porphyry dykes (Fig. 4). This magma is no doubt related to ascent of metamorphic
water and partial melting during eastward subduction of the oceanic Indian plate beneath the Burma plate (Fig. 2).
Conceivably, a porphyry copper deposit could be present somewhere beneath the Monywa ore bodies.

27. Vitamin B12 (cobalamin) was identified nearly 80 years ago as the anti-
pernicious anaemia factor in liver, and its importance in human health and
disease has resulted in much work on its uptake, cellular transport and
utilization. Plants do not contain cobalamin because they have no cobalamin-
dependent enzymes. Deficiencies are therefore common in strict vegetarians,
and in the elderly, who are susceptible to an autoimmune disorder that
prevents its efficient uptake. In contrast, many algae are rich in vitamin B12,
with some species, such as Porphyra yezoensis (Nori), containing as much
cobalamin as liver. Despite this, the role of the cofactor in algal metabolism
remains unknown, as does the source of the vitamin for these organisms. A
survey of 326 algal species revealed that 171 species require exogenous
vitamin B12 for growth, implying that more than half of the algal kingdom are
cobalamin auxotrophs. Here we show that the role of vitamin B12 in algal
metabolism is primarily as a cofactor for vitamin B12-dependent methionine
synthase, and that cobalamin auxotrophy has arisen numerous times
throughout evolution, probably owing to the loss of the vitamin B12-
independent form of the enzyme. The source of cobalamin seems to be
bacteria, indicating an important and unsuspected symbiosis.
Monywa
Monywa is a city in central Myanmar and situated on the eastern bank of the
Chindwin Rive, Mandalay Division. It lies 136 km north-west of Mandalay
along the Mandalay-Budalin branch railway line. Monywa serves as a major
trade center for India and Burma through Kalay Myo road and Chindwin river.
The name Monywa comes from "Mon" meaning "cake or snack food" and
"Ywa" which is the Myanmar word for village. There is a legend which says
28. that in the old days a Myanmar king fell in love with a seller of cakes from this
town and made her his queen. The original name some say, is Mon - thema-
ywa or " Village of the woman cake seller". There has been a big village at
Monywa from the Bagan Period. The classical name for Monywa is
Thalawadi. The chronicles mention that Monywa was one of the places
where King Alaungphayar encamped for the night on his campaign to
Manipur in 1758. During the Myanmar kings' time Monywa remained just a
big village as the administrative centre for the region was at Ahlon. It was
only a year after the Annexation of 1886 that Monywa became the
Headquarters of the Lower Chindwin District. In the last few years with the
legalizing of the border trade with India, Monywa has grown into a bustling
trading.
Monywa Town
In Monywa town, there are busy markets, popular restuarants, a Degree
College affiliated to Mandalay University, a Technical High School, and soon
there will be an Institute of Economics, the second after the one in Yangon.
Monywa Hotel, now privatised, has comfortable four-room bungalows with
attached amenities, all air-conditioned. centre, second only to Mandalay in
the Upper Myanmar region.
If you are travelling to Monwya by car you should stop about 20 kilometres
before you reach the town to visit this most unusual Buddhist temple complex
on 37 acres of land which is part of the Mohnyin Forest Monastery retreat.
The pagoda was started on 20th June 1939 and completed on 2nd March
29. 1952.It was the brain-child of the famous Mohnyin Sayadaw whose life-like
effigy can be seen nearby.
If you can go at the beginning of the Myanmar month of Tazaungmone (
usually around November), you can see the annual pagoda festival, which
goes on for several days when the villagers from all around come to enjoy the
music and dancing, and buy from the various stalls set up by sellers from all
over the country.
Interesting Places
Thanboddhay Pagoda
If you are travelling to Monwya by car you should stop about 20 kilometres
before you reach the town to visit this most unusual Buddhist temple complex
on 37 acres of land which is part of the Mohnyin Forest Monastery retreat.
The pagoda was started on 20th June 1939 and completed on 2nd March
1952.It was the brain-child of the famous Mohnyin Sayadaw whose life-like
effigy can be seen nearby.
Some visitors say that this Pagoda reminds them of Borobodur, as it is similar
in architectural design. Unlike Borobodur this is a modern place of worship,
well maintained, and with interesting samples of modern Buddhist art. There
are many different Buddha images, row upon row in ascending tiers in niches
along the walls: the total number is 582, 257, an amazing figure! Unlike most
of the pagodas in Myanmar, the entrance is not guarded by Chinthes, the
mythical lions, but by statues of a pair of magnificant white elephants which
are sacred and auspicious in Buddhist symbolism.
Thanboddhay is the only pagoda with this unique shape in the whole country.
The square temple base (each side about 166 feet) which worshippers can
30. enter is topped by receding terraces, with myriads of small stupas (864 in
number) surrounding the central golden chedi, 132 feet in height.
Tourists can study and take photos of the twenty tagundaing, huge decorated
pillars, and also big masonary fruits in the shape of bunches of bananas and
coconuts, water melon, mangos, jackfruits, papaya and so on . These fruits
are also objects of veneration for the local farmers.
If you can go at the beginning of the Myanmar month of Tazaungmone (
usually around November), you can see the annual pagoda festival, which
goes on for several days when the villagers from all around come to enjoy the
music and dancing, and buy from the various stalls set up by sellers from all
over the country.

Bodhi Tahtaung and Po Khaung Taung
From Thanboddhay Pagoda you can go by car about five miles along a good
branch road to Po Khaung Taung, a small range of hills in the Monywa area.
There you will see more unusual sights not found in other parts of Myanmar.
First you should stop for a while in the fast growing forest of one thousand
Bodhi trees (Ficus religiosa); this Bo or pipal tree is sacred to all Buddhists
because Gaudama Buddha attained Enlightenment while meditating under
this tree.
A much venerated Sayadaw now popularly known as the Bodhi Tahtaung
Sayadaw who can make your wishes come true, first started planting this
forest grove about two decades ago. Each tree has a large Buddha image
underneath, and many Buddhist come to pay obseisance there. It is a
31. pleasant, peaceful place, filled with the song of birds, in a protected
environment where nature and men are in perfect harmony.
Just beyond Bodhi Tahtaung, a short stroll towards the east will bring you to
the Po Khaung Taung, a range of hills where you can see one of the largest
reclining Buddha images in the world. Measuring 300 ft in length it is even
bigger than the colossal Shwethalyaung reclining Buddha image in Bago
(Pegu) which has a length of 180 ft. only. The head is 60 ft. in height. It was
only built in 1991 and up to now there is still no roof or shelter to protect it
from the elements.
This huge image has a hollow cave-like structure inside and you can walk
from the head to the feet. You will then see inside 9,000 one foot high metal
images of the Buddha and his disciples in various postures. There are also
representations of some of the important events in the life of the Buddha.
If you are interested in Buddha footprints you can study the 108 auspicious
symbols which are depicted on the soles of this huge image.
Aung Sakkya Pagoda
Near the reclining Buddha image, also on Po Khaung Taung range is the
Aung Sakkya Pagoda , 441.75 ft in height (including the base of 216.75 ft).
This pagoda is a landmark for the area around Monywa as it can be seen
from afar. It is surrounded by 1,060 smaller satellite pagodas which shelter
over a thousand sacred images of the Buddha.
Pho Win Hill
The hills have probably been occupied since the dawn of human habitation in
Myanmar; to the south - west lies the Pon Daung Pon Nya mountain range,
32. where the fossilised remains of Pontaung Mon's may have lived 30 million
years ago - were found.
The caves themselves contain Buddhist statues and murals dating to the
17th and 18th centuries. Most exhibit the Inwa style, though some may date
as for back as the 14th to16th centuries. A covered stairway climbs a hill to
the main cave shrine, but there are dozens of large and small caves in the
area filled with old Buddha images. There are over 400,000 images in these
and other nearby caves.
Shwe Ba Hill
Shwe Ba Hill, just beyond Pho Win Hill, features unique pavilions cut from the
surrounding sandstone and filled with plain Buddha images.
Shweba Taung is on the West Bank of Chindwin river.
There, temples and caves are curved out of volcanic rocks and inside walls of
some caves are decorated with 13 century / 18 century mural paintings.
Travel Tips: Entrance Fees : US$5
Shwe Gu Ni Pagoda
The Shwe Gu Ni Pagoda is about 20 miles east of Monywa. The Buddha
image in the pagoda is offered (stick) by gold foils and the face of the Buddha
image could not be make out very easily. Typical black and gold lacquer ware
from nearby Kyaukka is the festival's speciality. Held from the 5th to the 8th
waning day of Kason. Shweguni Pagoda is famous for its magnificent
architecture.
Nearby Attractions
Monywa can also be the base for visiting Kyaukka. Kyaukka , a town about
33. ten miles to the east, second only to Bagan as a center for the Myanmar
lacquer-ware cottage industry. A few hours drive will also bring you to
Twintaung hill, an extinct volcano whose crater now forms a beautiful lake.
The surrounding area has lush vegetation, and views of the area from the rim
of this crater lake is breathtaking.
The Ledi Kyaung Monastery is also well worth visiting. Built by the famous
Ledi Sayadaw, a renowned Pali scholar, there are now 806 stone slab
inscriptions which preserve some of the Sayadaw's writings.
A few hours drive will also bring you to Twin Taung Hill, an extinct volcano
whose crater now forms a beautiful lake. The surrounding area has lush
vegetation, and there are lovely views of the area from the rim of this crater
lake.
Visitors are welcome to travel to Monywa and environs; see the interesting
places and scenic views, and take back memorable experiences of typical
Myanmar warmth and hospitality.
http://myanmartravelinformation.com/mti-mandalay/monywa.htm
Monywa is a city in Sagaing Division, Myanmar, located 136 km northwest of
Mandalay on the eastern bank of the River Chindwin.
Transport
It is served by the Mandalay-Budalin branch railway line, but is best reached
by bus as the road from Mandalay is in reasonably good shape. Monywa is
now linked by road to Budalin, Dabayin, Ye-U and Kin-U, and by rail to
Sagaing and the Mandalay - Myitkyina line.[1] River transport on the
34. Chindwin has always been important as it is navigable for 640 km (400 miles)
up to Hkamti during the monsoon season, and most of the year to Homalin.
Economy
Monywa is a major centre for trade and commerce and for agricultural
produce from the surrounding Chindwin valley, especially beans, orange,
pulses and jaggery (palm sugar). In addition, the local industry includes mills
for the production of cotton, flour, noodles, and edible oils. Sausages from
Alon called wet udaunk are quite popular, and Budalin longyi (sarong) is
known for the strength of the fabric and its checked patterns. Monywa's rough
cotton blankets are famous throughout Myanmar, and some can even be
found sewn up into knapsacks sold to unsuspecting tourists in Bangkok.
Other regional crafts include bamboo and reed products, bullock carts and
agricultural implements. The village of Kyaukka is well known for its
lacquerware utensils for everyday use.Black market goods from India,
especially saris and bicycle parts, pass through Monywa on their way to other
parts of Myanmar.The major tourist attraction in Monywa (although very few
tourists make it there, and facilities are very limited) is Mohnyin Thambuddhei
Paya, a Buddhist temple with a huge stupa resembling Indonesia's
Borobudur. It dates from 1303, although it was reconstructed in 1939. It is
said to contain over 500,000 images of Buddha.
Education
The city is home to: Monywa University
Politics
The insurgent Burmese Communist Party (BCP) was centred in the Monywa
35. area (west of the Chindwin River) for many years. Although the BCP is no
longer active, the Myanmar military presence in Monywa remains heavy.
Sagaing Division
Sagaing Division is an administrative division of Myanmar, located in the
north-western part of the country between latitude 21° 30' north and longitude
94° 97' east. It is bordered by India’s Nagaland and Manipur States to the
north, Kachin State, Shan State, and Mandalay Division to the east,
Mandalay Division and Magway Division to the south, with the Ayeyarwady
River forming a greater part of its eastern and also southern boundary, and
Chin State and India to the west. The division has an area of 93,527 km², and
population (1996) of over 5,300,000. The capital is Sagaing.
Sagaing Division consists of 198 wards and villages, 38 townships and eight
districts; Sagaing, Shwebo, Monywa, Katha, Kale, Tamu, Mawlaik and
Hkamti. The major cities are Sagaing, Monywa, Shwebo, Katha, Kale, Tamu,
Mawlaik and Hkamti. Mingun with its famous bell is located near Sagaing but
can be reached across the Ayeyarwady from Mandalay.
History
The Pyu were the first to in recorded history to populate the area of Sagaing
Division by the 1st century CE. The Bamar (Burmans) first migrated into
Upper Myanmar by 7th century CE. The area came under the Pagan
Kingdom certainly by the middle of 11th century when King Anawrahta (r.
1044-1077) founded the Pagan Empire, which encompasses the modern day
Myanmar.
36. After the fall of Pagan in 1287, the northwestern parts of Upper Myanmar
came under the Sagaing Kingdom (1315-1364) ruled by Burmanized Shan
kings. The area was ruled by the kings of Ava from 1364 to 1555 and the
kings of Taungoo from 1555 to 1752. Konbaung Dynasty (1752-1885),
founded by king Alaungpaya in Shwebo, became the last Burmese dynasty
before the British conquest of Upper Burma in 1885. The area became
Sagaing Division after the Burmese independence in January 1948.
Demographics
Sagaing
The Bamar (Burmans) are the majority ethnic group in the dry regions and
along the Mandalay-Myitkyina Railroad. Shan live in the upper Chindwin
River valley. A sizable minority of Naga resides in the north of north-west
mountain ranges and Chin in the south. Smaller ethnic groups native to the
Division include the Kadu and Ganang, who live in the upper Mu River valley
and Meza River valley.
Economy
Agriculture is the chief occupation. The leading crop is rice, which occupies
most of the arable ground. Other crops include wheat, sesame, peanut,
pulses, cotton, and tobacco. Sagaing is Myanmar’s leading producer of
wheat, contributing more than 80% of the country's total production. Forestry
is important in the wetter upper regions along the Chindwin River, with teak
and other hardwoods extracted. As in other parts of the country, reforestation
is not effective enough to maintain sustainable forestry. Important minerals
include gold, coal, salt and small amounts of petroleum. Industry includes
textiles, copper refining, gold smelting, and a diesel engine plant. The
Division has many rice mills, edible oil mills, saw mills, cotton mills, and
mechanized weaving factories. Local industry includes earthen pots,

Natural Blue-green Algae generated Twin Taung in Butalin Township
Mon Ywar District in Sagaing Division has already been decreased since
2012 that not any yield position it reached that Reverse System of Lake
surface water turn inside outs and turn ups for Revival is being
practiced today,” said U Sithu, the responsible person from Natural Blue-
green Algae Production.
“Since 2012, Production rate fell down, and in May 2013, no yield
at all was found. Main Problem is FRESH WATER INTRUSION. At the
moment, Revival the Blue-green Algae were tried to Reverse System of
Lake surface water turns inside outs and turn ups, and Tilapia Fish were
netted and other ways of Fishing. If one or two Tilapia Fish species
remain in Lake, they may be reproduced. Mainly, if we could prohibit
Fresh Water, Lake Water pH may become high as nature origin, Tilapia
could not exist anymore,” U Sithu said.
Workshop held at Nay Pyi Taw Office of the Ministry of Industry on 5th June 2014 for this issue, some Findings of Experts were
discussed.
Twin Taung Pit was once a Volcano, surrounded walls of the Lake was Igneous Rock that external water could not seep-easy
stated the Department of Geology; much more Urea Fertilizer use released a kind of toxic by chemical reactions poisoned Blue-green
Algae, and lessened its Growth Rate as Urea and water reacted in Lake diminishing temperature of 30 -35 C Blue-green Algae grow;
Averrhoa carambola (Local name Star fruit / Carambola) liquid input into Lake needs to be fresh but present use teashop discard gave
poison it was said.
U Sein Kyaing from Geology Myanmar Org. put up that Volcano Lava powder is the type of soil so good to absorb water, River
Water Pumping Land Use in Volcano Vicinity area drives Fresh water leaking into the Lake affecting Twin Taung of its High pH Natural
Ecosystem quite changed; Backlash that serious Nature Degradation occurred visible today as no more Spirulina and Twin Po (Edible
Insect extract from Twin Taung) Natural Resource as well.
Ways to Tackle the Problem-solving, he presented to Revival Twin Taung as originated as nature, there is no way to work out
either to move River water Pumping Drain Application outside 5 to 10 mile of Volcano area or to stop Water Pump-in Works as other
sites.
Professor Dr. Zaw Myint Ni, Head of the Department of Geology of Mon Ywar University suggested to review Chemical ratio
consumption and to control its use in the Lake, and to clear Fish in Lake by various types of nets.
“Nowadays Fish captured is not much like before; that is, 2-3 viss round per day compared with previous seizure 20 viss per
day whilst Twin Poe none. “
“Previous days Boat-ride like today was hard in the Lake, Fishing even harder due to densely grown Spirulina in the Lake
almost thick round 3 ft that Boat-rowing incapable in the Lake.”
“In present, even the Lake water color has already been changed in vision. Previous Spirulina Tablets were dark-green
previously but today the color totally changes to Banana-leaf green,” explained a Villager from Twin Taw Village who is fishing Tilapia.
Either generate or not the Blue-green Algae, there may stand the Pit Twin Taung, so not to be a wasteful case, either a Tour
Spot or a Relaxation Spot should be arranged. In present, there are over 20 Guests daily in record of Guest Book in the Lake Gate,” said
a Geologist.
The Spirulina Blue-green Algae is found in 3 Spots in the world such as Mexico, Africa and Myanmar, that is, Spirulina is the
very Unique Natural Resource.
