Dynamic processes of the Paleozoic Tarim basin and its significance for hydrocarbon accumulation-a review and discussion
2012, 23(4) doi: 10.1007/s12583-012-0262-5
The structural framework and evolution processes of the giant superimposed Tarim basin in Paleozoic Era are controlled by three main factors: (1) features and structures of the basin basement; (2) deep mantle dynamics process (such as the Sinian rifting and the Permian plume-related magmatic activities); (3) the powerful regional compressional or compresso-shear stress regime generated by the orogenic movement from surrounding regions. The latter of which occurring in multiple episodes is the most important factor for the Paleozoic ...
