Mesozoic magmatism and polymetallic mineralization in the eastern part of the North Huaiyang tectonic zone

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.
