LEAD ISOTOPE COMPOSITIONS OF MESOZOIC GRANITOIDS AND LEAD ISOTOPIC PROVINCES FROM ANHUI PROVINCE
安徽中生代花岗岩铅同位素组成与铅同位素省划分

According to 71 Pb isotopic data of Mesozoic granitoids and their lead isotope characteristic pattern from different aeras in Anhui, the authors divide Anhui into 6 Pb isotopic provinces: Dabieshan province (A), North Huaiyang-Fubu province (B), North Anhui province(G), North Yangtze province (C), South Yangtze province (D) and Tianchang-Tai lake province (F). The authors also suggest that the lead isotope characteristic pattern of Mesozoic granitoids from each lead isotopic province is closely related to the chemical composition, the age, and the regional metamorphism grade of basement rocks
