Petrology and geochemistry of the Fuling mass in Jixi, southern Anhui

Abstract：Detiled field geological mapping and geochemical study show that the Fuling rock mass in southern Anhui is enriched in Si ,Al，ａlk , high-field strength elements ,REE ,Rb and depleted in Sr and Ba,belonging to aluminous A-type granites. These characteristics suggest that the magma originated by partial melting of the lower crust. The rock mass rose and was emplaced rapidiy along fault in a post-orogenic extensional environment,and the magmatic differentiation was incomplete.
