Early Cenozoic Multiple Thrust in the Tibetan Plateau

Figure 5

Generalized crustal profile across the Tibetan Plateau. Explanation: red line: major thrust system; dashed red line: upper boundary of Indian continental crust shearing thrusted away from subducted Indian Continental Plate; dotted white lines: deep shearing thrust in middle-lower crust; black fine lines: strata or foliation in middle-upper crust. Deep structures of Himalaya and southern Tibet are inferred from seismic reflection profiles of INDEPTH-I~II [17, 18]; deep structures of central Tibetan Plateau are inferred [19] from seismic reflection profiles across Qiangtang Block [20, 21], and the receiver function profile and wide angle seismic data of INDEPTH-IV [22, 23] in the northern Tibetan Plateau were used to interpret middle-lower crustal structures shown herein [24]. Deep structures marked by the black and white dotted lines are new interpretations of the seismic profiles. Letter symbols are the same as on Figures 2 and 3.
