Zircon U-Pb geochonology and Hf isotopes of the Early Cretaceous Rena-Co rhyolites from southern margin of Qiangtang, Tibet, and their implications
西藏羌塘南缘热那错早白垩世流纹岩锆石U-Pb年代学和Hf同位素及其意义

The direction of subduction of Bangong Lake-Nujiang oceanic crust has long been a debate in the topic of geological evolution history of Tibetan Plateau. Informed research shows that large amount of Cretaceous igneous activity spreads widely on northern Lhasa terrane, south of Bangong Lake-Nujiang suture zone. However, small magmatic activity of the same era was discovered on the north side of the suture zone. An isotopic and geochronologic study of this paper presents zircon LA-ICP-MS U-Pb data and Hf isot...
