| Abstract: | Based on field investigation, reflecting seismic profiles and other data, deformation style and its distribution in North Tarim basin, NW China, are discussed in this paper. North Tarim basin includes Kuche foreland basin thin-skinned deformation zone and foreland cratonic deformation zone in which thick-skinned(basement - involved)deformation dominates, thin-skinned deformation ranks second. Vertical and lateral variation of deformation style in Kuche foreland basin are controlled by the occurrence of detachment layers, tectono-stratigraphic units and the change of compressive stress magnitude. In foreland cratonic region, the distribution of deformation style is controlled by lithomechanical property, decoupling or detachment surfaces, pre-existed tectonic framework and compressive stress magnitude. |
