Metamorphic and magmatic evolution of the Paleoproterozoic gneisses in the Sancheong area, Yeongnam Massif, South Korea, and their implications to the tectonics in the Northeast Asia

摘要

Highlights ? The study area underwent intermediate-P/T metamorphism between ca. 1920–1880Ma. ? The study area also underwent low-P/T metamorphism at ca. 1860Ma. ? The post-collision igneous activity occurred between two metamorphism (1880–1860Ma) ? The study area underwent collision and post-collision process during 1920–1860Ma. ? The study area may be correlated to eastern Cathaysia Block in the South China Craton. 展开▼
