The Tectonic Setting Of Yinshan Lead-Zinc Deposit In The East Of North Huaiyan Tectonic Zone

The paper discusses the deep tectonic setting of Yinshan lead-zinc deposit and emphaticly studies geological features of two fault belt and relationships between deep structures and mineralization.By analysing geochemical characteristic,their metallogenic characteristic and tectonic environment are disclosed.Through field survey and tests,the paper shows the feature of ore-body,ore,deposit origin,enhancing realization in origin and disco-vering porphyly-type lead-znic-deposit.The paper not only studies the mircostructure,malcrostracture features of ore-controlling fault system and kinemafic analysis but also deeply states the breccia pipe structure.lt considers that Yinshan Lead-zinc Deposit is controlled by three-level structure condition.The NE-trending left-laterl structure movement is mainly controlling factor.Based on the study.the paper has surmarized the ore-rich regulation. Besides,the paper analyses the stress field of ore-forming peroid.At last the paper discusses the relationship between evolution of structure and mineration.
