Abstract: Abstract Triassic magmatic rocks are widely exposed in the northern Qiangtang Block in Tibet. However, their petrogenesis and relationship to the evolution of Tethys Ocean are matters of debate. Here we report zircon U-Pb ages,… read more here.

Abstract: ABSTRACT Late Early Oligocene mantle-derived potassium (K)-rich lavas occur widely in the Qiangtang Block, central Tibet. However, it remains ambiguous whether partial melting of crust beneath central Tibet occurred in the Oligocene. Here, we report… read more here.

DOI: 10.1080/00206814.2020.1867912
Abstract: The Mid-Late Mesozoic magmatic arc in southern Qiangtang block was associated with the long-lasting subduction of the Bangong-Nujiang Tethyan and the subsequent Lhasa-Qiangtang collision. The detai... read more here.
