Study on Metallogenic Characteristics of Magmatic Rocks in the Eastern Section of Northern Huaiyang Metallogenic Belt
The Mesozoic magmatism is strong in Northern Huaiyang metallogenic belt of Anhui prov-ince.There is a close relationship between diagenesis and mineralization in time,space and genesis.Molyb-denum,lead,zinc,gold and other polymetallic mineralization are widely developed.Based on the study of the basic geological characteristics,metallogenic geological processes and metallogenic rules in the eastern part of Northern Huaiyang metallogenic belt,it is found that the mineralization of the early Upper Creta-ceous in this area is dominated by Au,Ag,Pb,Zn and other minerals,and the related magmatism is the volcanic rocks and intrusive rocks of high potassium calcium alkali and potassium basalt series.The mineral-ization of the late Cretaceous is dominated by Mo mineralization,and the related magmatism is mainly alka-line pluton.The late Cretaceous(quartz)syenite-granite porphyry should be taken as the focus in the process of prospecting and prospecting in Beihuaiyang area.
