The northeastern Tibetan plateau results from the superposition of the Caledonian Qilian orogenic belt and Cenozoic reactivation following continental collision between the Indian and Asian *** order to identify the constraints on the Qilian orogenic mechanism and the expansion of the plateau,we carried out a 430-km-long wide-angle seismic experiment between Jingtai and *** herein present the crustal P-wave velocity structure model resulting from the interpretation of this wide-angle seismic *** principal characteristics of the crustal velocity model include:(1)thinning of the crust from south to north within a range of about 48-54 km with some undulation of the Moho beneath the Northern Qilian block;(2)the thickness of the sedimentary layer and its average P-wave velocity exhibit the obvious tectonic division of the Qaidam-Kunlun-West Qinling belt,the central and Northern Qilian,and the Alax blocks;(3)the lower crustal layer has a P-wave velocity of 6.6-6.8 km/s beneath the Qaidam-Kunlun-West Qinling belt, Northern Qilian orogenic belt and Alax block,but has a very low value of B.4-6.5 km/s beneath the Central Qilian block;and(4)the Central Qilian block shares a similar crustal P-wave velocity-depth relationship with the Sierra Nevada arc or the accretionary *** Qaidam-Kunlun-West Qinling and the Northern Qilian orogenic belts have a crustal P-wave velocity-depth relationship characteristic of the crust of the global average *** particular Vp-depth relationship beneath the Central Qilian orogenic belt may result from a Caledonian accretionary orogeny or from the delamination of the ecologized lower crust during the arc-continental collisional orogeny,The lower velocity layer(LVL)exists at the bottom of the upper crust,to the north of the middle of the central Qilian *** infer that this LVL plays an important role as an intracrustal decollement to expand the plateau.
