Tectono-sedimentary evolution of piggy-back basin: Example from Kuqa fold and thrust belt, northern Tarim basin, northwest China

The Baicheng (拜城) piggy-back basin was part of the intracontinental foreland basin system of southern Tianshan (天山) Mountains. It was formed on a thrust-and-fold belt induced by Mio-Pliocene collision between southern Tianshan Mountains and Tarim craton that controlled the thick synorogenic basin fills. Sedimentological analysis and a restored cross-section based on seismic data and field studies revealed three tectono-depositional sequences of...
