Maximum sizes (mm) of kimberlite indicator minerals (KIM) findings were plotted. The most perspective magmatic bodies for
diamond occurrence are Rakefet, Har Alon, Bat Shelomo and Kerem Maharal, which have largest size of KIM findings.
At present the main target of Shefa Yamim company is to
search for diamondiferous magmatic bodies within the
Upper Creataceous magmatic rocks of the Carmel and in
particular to determine their vents and sampling
and study of the all samples taken to determine:

RAKAFET: MICRODIAMOND
SAMPLE, APRIL 2004
RESULT: 1 X MICRODIAMOND
Geological research has indicated that two different mineral associations appear in the area:
Pyrope-Spinel association related to the Upper Cretaceous volcanism, and developed on the Eastern slope of the
Mount Carmel and;
Moissanite – Corundum association related to the Miocene volcanism. Surveys conducted in the drainage basin
indicate the primary diamond source to be the Cretaceous Volcanic rocks on Mount Carmel situated on the
southern flank of the Qishon Valley. The Pyrope – Spinel association was particularly researched because of it
relationship with diamonds this was confirmed by the finding of a micro diamond from a small sample taken by
De Beers in their laboratory in Kimberly (South Africa) from sample S-300 on Mount Carmel – Rakefet area.
Shefa Yamim has executed field study of almost all Mount Carmel magmatic bodies. Points of sampling should
be located within magmatic bodies, diluvium, terraces and in rivers. More than 160 samples were selected from
the Carmel area. Heavy minerals fraction from the samples were studied by microscope, more then 400,000
grains of kimberlite indicative minerals were found, these include: Garnet (Pyrope, Almandine, Grossular,
Andradite), Spinel, Cr-Spinel, Ilmenite, Picroilmenite, Rutile, Zircon, Corundum (also Ruby, Sapphire),
Moissanite, Chromite, Chrome-Diopside, Clino-Pyroxene, Pyroxene, Amphibole, Kyanite, Magnetite,
Phlogopite, and Hematite. More then 2,860 geochemical testing by SEM was done at IGS Jerusalem and De
Beers Africa Exploration Laboratory. Also 51 thin sections were analysed at the Ben Gurion University from
various magmatic bodies on Mount Carmel. An Electromagnetic Survey (EM) survey and mapping was
completed at 7 magmatic bodies of Mount Carmel by Creo Design (Pty) Ltd. (South Africa). Geochemical
testing indicated same volcanic rocks are para-kimberlite lamprophyre rocks (De Beers). Also petrography
determination (Ben Gurion University) shows presence of eclogite in the samples.

3. Ilmenite: within Garnet and /or within Pyroxene
4. Garnet, Spinel, Ilmenite, Pyroxene, Amphibole individually within host rock
These relationships may reflect the order of formation of these minerals: Spinel/Ilmenite; Garnet; Pyroxene.
