Geology/Basin effected by tectonic setting


Sir can you please tell me about any basin formed effected by strike slip tectonic settings in Pakistan ??


If we move from NE to SW along the mountain ranges, we find Jhelum Fault, Kalabagh F., then minor strike-slip faults within the Sulaiman Range; Harnai F. and finally  the famous Chaman F. and the Ornach-Nal Fault. All of these are dominantly strike-slip faults, and have affected formation of basins in exposed areas, somehow or the other. As you may be aware, the Indian Plate (IP) collided with the Eurasian Plate in Early Cenozoic, but the main collision started sometimes in Eocene. And the northward movement of IP is still continuing. The compression was dominant in the beginning but as the folded rocks took their orientation and the ranges took their shape the strike-slip gradually became the dominant force.

Potwar as a whole, in particular,is bounded by strike-slip faults on its either sides with generally E-W oriented structures, increasingly becoming NE-SW as they near the Jhelum fault.

I am a petroleum exploration geologist with about 40+ years of diversified experience. I can answer questions on stratigraphy, log interpretation, field studies based on set of logs and core results, general geology etc. Can provide guidance for career planning in earth sciences. Can not help in questions about hard rocks, igneous petrology & mineralogy, sequence stratigraphy and seismic.


Petroleum Exploration - field geology, stratigraphy, prospect generation, interpretation of satellite imagery (visual), log interpretation.

Retired in May, 2006 as Senior Manager Exploration from Pakistan Petroleum Limited after serving 26 years. Since then continuing in active service with petroleum exploration companies.A cumulative experience of about 40 years covers 30 years in petroleum exploration, 5 years hydrogeology experience in Libya, and about 5 years of dam geology in Pakistan.
