安徽北淮地区中生代岩浆活动可分为早、晚期两期:早期高钾钙碱性和钾玄岩系列、晚期碱性岩系列。从岩石地球化学特征、岩浆活动特征等角度分析,多金属成矿作用与中生代岩浆活动关系密切。
The Mesozoic magmatic activity in the Beihuai area of Anhui Province can be divided into two phases of early and late phases: the early high-K calc-alkaline and potash rock series and the late alkaline rock series. From the geochemical characteristics of rocks and the characteristics of magmatism, polymetallic mineralization is closely related to Mesozoic magmatic activity.
