Abstract:

Using the basic geological survey and geochemical method，conducts research of the ore belt structural，mine area structural，ore-veins，ore-body characteristics and ore mineral characteristic，the metallogenic regularity of Jinlongshan metallogenic belt’s ore-veins is NE or NW trending fault breccia mineralized bodies and EW-trending interlaminar shear zone mineralized bodies intersection.The extension of the main ore-veins which distribute to the north east is greater than the extended regularity.And Ore-controlling fracture is based on the main fault based，secondary faults supplement.The NE to main structural metallogenetic model had been set up，and which shows that: Sinistral strike-slip tectonic belt is loss flower structural in the section.Gold veins and its upper mercury-antimony veins developed in the faults and formed the fault breccia mineralized bodies，and also developed in the shear zones beside the faults and formed the interlaminar shear zone mineralized bodies.There are four strain centers in Xitonggou-Jinlongshan metallogenic belt.But only the strain center of Dongping-Lianghe has not fond any deposits.It is the vision area of the next prospecting work.At the same time，there also is a strong deformation zones and weakly deformed domain in Zhenan-Longwanggou and Xitonggou-Tiechang tectonic deformation zones which also are the key mineralization area，and can be used as mineralization prospects.

Key words: ore-controlling structural, mineralization regularity, metallogenetic model, Jinglongshan gold deposit, South Qinling Mountains
