Influence of Regional Tectonics on Trap Integrity in Zagros Foothills and Foreland, Kurdistan and SE Turkey
Arabia-Eurasia collision was caused by non-orthogonal transpressional closure of Tethys. Deformation partitioned into a broad belt of folds and thrusts, a large, seismically active, orogen-parallel right-lateral strike-slip fault (the Main Recent Fault), and an array of NNW-SSE right-lateral strike-slip and oblique-slip faults, recognised from new field data in SE Turkey and NE Iraq (Kurdistan). These faults are difficult to recognise and quantify in outcrop and in seismic data. However, they are generally long-lived, can segment large anticlines, and can have a highly detrimental effect on trap integrity.
