This is presentation about gravity faults as also call normal faults Here give the information about this topic and the information is very useful for geology students. In this presentation i covered all detail related to this topics. So i hope this presentation if you like and useful for your study. So if you like this presentation you can follow me on slideSher i share useful materials only on slidesher. Darshan Darji Studying msc Geology at M. G science institute

- 3. What is Fault ? PART 1
- 4. Enter title There are three main types of fault which can cause earthquakes: normal(gravity) Fault , reverse (thrust) Fault and strike-slip Fault. A "Fault " may be defined as a fracture along which block of rock have been displaced relative to each other. What is Fault ? https://www.thoughtco.com
- 5. Enter title Normal fault An inclined fault in which the hanging wall has slipped down relative to the footwall. Example- San Andreas Fault in California. Definition of Fault Type Reverse fault A geological fault in which the hanging wall appears to have been pushed up along the footwall. Example- Glarus thrust (Switzerland) Strike slip fault A fault on which the two blocks slide past one another. Example- North Anatolian Fault and the Alpine Fault.

- 8. Origin of Gravity faults. PART3
- 9. Enter title Normal Faults: This is the most common type of fault. It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming. Long, deep valleys can also be the result of normal faulting. Tensional stress produces By Normal faults, That's the called gravity faults. Origin of Gravity faults Kanab, Utah. (App-Pinterest) (Website -Study. Com)
- 11. Enter title The term 'en echelon' refers to closely-spaced, parallel or subparallel, overlapping or step- like minor structural features in rock (faults, tension fractures), which lie oblique to the overall structural trend. These are relatively short faults which overlap each other ENECHELON GRAVITY FAULTS http://bio-geo-terms.blogspot.com http://bio-geo-terms.blogspot.com/
- 13. Enter title HORST - When Two Parallel Normal Faults Hade Away From One Another and The Rock Between Them is uplifted to Form a Ridge, The structure is called a "HORST" The >600-km-long Satpura mountain range of central India is usually considered as a horst, separated by normal faults from the Tapi and Narmada grabens. ... Erosion of the southern front of the Satpuras produces a large fault-line scarp, an illusory normal fault. HORST AND GRABEN
- 14. Enter title "Grabens" are long and relatively narrow fault throughs bounded by parallel high angle faults. This structure is produced when the two parallel normal faults hade towards each other and the rock beds between them are thrown down Under The influence of gravity forming a topography low. Tensional crustal forces which pulls the crust apart are responsible for the formation of rift faults.Grabens typically occur along crests of upwards. GRABEN
- 16. Enter title 1 Tilted block faulting, also called rotational block faulting, is a mode of structural evolution in extensional tectonic events, a result of tectonic plates stretching apart. When the upper lithospheric crust experiences extensional pressures, the brittle crust fractures, creating detachment faults. TELTED FAULT (https://www.sciencephoto.com) (Wikipedia)
