... during the Cenozoic Indo-Asian collision. To determine when and how the basin was developed, we conducted detailed geologic mapping and analyses of a dense network of seismic reflection profiles from the southern Qilian Shan-Nan Shan thrust belt and northern Qaidam basin. Our geologic observations...

... with cosmogenic isotope laboratory work. Peer reviews by An Yin and an anonymous reviewer improved the quality of this manuscript. To the north of the Anyemaqen Shan, and between 99°E–101°E, active shortening appears to be accommodated by arrays of thrust faults on opposing sides of the Qilian ShanNan Shan...
