Abstract:

Through the field investigation and indoor rock mineral research in South Qinling，Jinlongshan primary ore types is divided into four categories by the structure of the metal mineral occurrence state：disseminated gold ore，lamellar gold ore，veinlet gold ore，structural breccia type gold ore.The disseminated gold ore and lamellar gold ore occurrence in the compressive shear deformation interlayer shear zone，which is nearly EW to distribution and being squeezed from S，N and W，and established the interlayer shear zone type ore is the main ore type.Interlayer shear zone type ore is the main ore type，and tectonic breccias’ type ore is secondary.The formation of interlayer shear zone type mineralization body is the result of the ore-forming fluid permeating stratum and the between layers，while the fracture structural breccia type body is formed by the ore-forming fluid spreading along the fault belt.The mineralized bodies of Jinlongshan gold deposit is formed by the interlayer shear zone type mineralization and the tectonic breccia type mineralization.In this paper，we study the ore types and mineralization types，analyze the mineralization mechanism，and correct the mistakes of the past ore body connection.It will provide a basis for future orebody connections，also has guiding significance for gold deposit exploration in Jinlongshan gold deposit.

Key words: ore type, mineralization body, Jinlongshan gold deposit, Shaanxi Province
