Relationship between deep structure and distribution of mineral deposits in Qinling region

Abstract

Detailed studies on geophysical data and metallogeny of the Qinling region reveal the relationship between the deep crust-mantle structure and the distribution of mineral deposits. In the East Qinling, the Mesoznic mineralization intensity is mainly controlled by the Lushan deep fault zone. The differences of mineral deposit types between the East and West Qinling are related to the distinction of rheological adjusting actions of the crust-mantle. The three-dimensional structure of grade separation bridge pattern controls the distribution of mineral deposits, especially to the distribution of Mesozoic large deposits.
