ZHANG Hong1,DAI Sheng-qian2,GUAN Yun-cai2,WU Hai-quan2(1.College of Earth Sciences,Jilin University,Changchun 130026, Jilin, China;2.Anhui Institute of Geological Survey,Hefei 230001,Anhui, China)  
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.
