Abstract

Abstract

Located in Zhashui-shanyang basin of abundant mineral resources, Chigou area has been attracting more and more concern in recent years. By studies on wall rock alteration, characteristics of magma, ore features and the their ages, combined with the characteristics of Cu-Mo inside(Chigou area) and Au outside(Baishagou area), we have made progressive exploration achievements and confirmed that Chigou Cu-Mo deposit is similar to the typical porphyry ore deposits. Predecessors have done lots of researches related to mass bodies, but little attention has been paid to tectonics-magmatism. Through the tectonic and magmatic studies in Chigou area, we are informed that this area formed in the subduction to the extension stage during the early and middle Yanshanian. In that condition, the deep substance was easy to upwell and form porphyry. Based on the results, we established the model of tectonic-magma-mineralization in Zhashui-Shanyang area. The tectonics not only controls the magma forms, but also controls the mineralization in genesis and space. The finding has an important guiding significance to identify the extension of deep magma bodies and the prospecting work arrangement in the future.
