Origin of the Cenozoic porphyry Cu deposits in southern Tibet

, 2014
The Gangdese magmatic belt features extensive Cenozoic magmatic rocks that record geodynamic changes related to the India–Asia collision starting at ~55–50 Ma. Paleocene–Eocene magmas throughout the belt have similar continental arc features. Their intrusive rocks have intermediate [La/Yb]N and intermediate-to-low Sr/Y ratios, negative Eu anomalies ...
