A Structural Interpretation Model and Restoration of the Mesozoic Proto‐basin for the Kuqa Depression, Tarim Basin

A thrust-fold belt consisting of a series thrusts and buckling folds developed in the Mesozoic Cenozoic strata within Kuqa Depression, Tarim Basin. In this study, structural interpretation model Depression is established proto-basin reconstructed on basis outcrop geology along basin margin, seismic, well-log CEMP data. The called ‘delaminate contractional deformation’, which emphasizes decoupling between Cenozoic, Mesozoic, pre-Mesozoic basin-basement but there no unified detachment. has shortening amount ranging from 12 km to 16 depth involved deformation ranges 21 28 km. prototype by sub-basin superposed transitional zone uplift at northern edge Craton southern Tianshan orogenic wedge formed Hercynian orogeny.
