AbstractThe Hoh Xil Basin (HXB) was located in the foreland of the proto-Tibetan Plateau and has obtained a high elevation and thick crust since the Late Oligocene. However, crust thickening cannot be explained by the limited amount of upper crustal shortening and requires a further mechanism. Based on a linear dense nodal array, we use the receiver function method to study the detailed crustal structure beneath the HXB. Our images reveal that the HXB crust has been thickened to >70 km and is thicker than the protoplateau's crust. A series of north-dipping interfaces imaged in the lower crust implies widespread imbrication structures. Considering the uplift history of the plateau, we propose that isostatic-driven adjustments could equalize crustal thickness variations across the protoplateau margin in the Paleogene, and the HXB was elevated by extensive imbrications accommodated to a northward injection of the protoplateau lower crust in the Late Paleogene.
