Geology/Techtonic of Balochistan


what type of fold in mountains of Baluchistan? (also share the literature link)
and what the importance of chaman fault ?
waqar Ahmed


Tectonically southern two third of Balochistan represents what is called an 'Accretionary Prism'. You can call them the thrust folds.

The junction of the Arabian Plate and the Pak-Iran Makran region of Balochistan falls along the Oman Trench in the offshore. The Arabian Plate is subducting below the Makran region that has resulted in the uplift of predominantly the post-Eocene rocks, which accreted (layers on top of one another) that has buried the Eocene and the older rocks very deep, which at places are beyond the drillable depth.

Chaman Fault is a right lateral strike-slip fault marking the plate boundary between Indian (to the east) and the Eurasian (to the west) tectonic plates.The above publications will also be helpful for the second part of your question.
