羌塘盆地白垩纪以来快速隆升剥蚀的热年代学证据
Thermo chronological evidence for rapid uplift and denudation since Cretaceous in the Qiangtang basin
摘要
Abstract
The uplifting and denudation of complex rock mass in the central uplift zone of the Qiangtang basin in the hinterland of the Qinghai-Tibet Plateau were studied based on apatite fission-track dating method.The results showed that the apparent ages of 15 apatite fission-track samples were (57.0±5.0) ～ (118.0±7.0) Ma, and the peak ages decomposed from the mixed ages were (33.0±6.0) ～ (132.0±7.0) Ma in the study area.The tectonic uplift of the Qiangtang basin mainly occurred in the early Cretaceous, late Cretaceous and Cenozoic stages suggested by the inversion results of apatite fission-track thermal evolution history and other evidence.The late Cretaceous uplift (100.0～80.0) Ma is the main uplift among the three tectonic uplifts, and its uplift and denudation thickness was about3.200 km.The results have reference significances for the study of the uplift process in the hinterland of the Qinghai-Tibet Plateau.关键词
