Structure and tectonic evolution of the western continental margin of India: Evidence from subsidence studies for a 25–20 Ma plate reorganization in the Indian Ocean

摘要: The western continental margin of India developed by Mesozoic rifting and has subsided undergone further tectonic modification during India’s northward movement collision with Asia. Segmentation the apparently been controlled partly inheritance Precambrian structures, across one which different rates subsidence degrees stretching have occurred. At about 25–20 Ma, following a widespread erosional unconformity, rate greatly increased both on shelf and, in particular, seaward edge (hinge line). This occurred reorganization plates region Indian Ocean, coincided greater resistance to underthrusting beneath Asia, may be related enlargement plate from Owen fracture zone westward Dead Sea-Gulf Aqaba shear zone.
