摘　　要：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。Mesozoic magmatism in the North Huaiyang area,Anhui can be divided into two phases： early high-potassium and calcium alkaline and shoshonite series,and late alkaline rock series.Combination of petrogeochemical characteristics,magmatic activity features,etc indicate polymetallic mineralization was closely related to Mesozoic magmatism.magmatic activity.
