Characteristics and Prospective of the Porphyry Cu Mineralization in the Saishitang Cu Deposit,Xinghai,Qinghai,China

The Saishitang Cu deposit,which locates in Xinghai,Qinghai,has features of porphyry copper mineralization.The deposit area contains multi stages and various types of intermediate-acidic intrusive bodies.The Cu mineralization of the Saishitang deposit occurred mainly in diorite porphyrite,granodiorite porphyry,plagioclase granite porphyry,quartz porphyry,and explosion breccias at the end of the intermediate-acidic magmatic activities.Host-rock alterations are strongly developed with zonations.A breakthrough on copper exploration in this deposit area may have achieved if more attentions on the prospecting alteration zones of diorite porphyrite,granodiorite porphyry,plagioclase granite porphyry,quartz porphyry,and explosion breccias were paid.
