DOI: 10.1080/00206814.2019.1597391
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.
