Gold Deposit Mineralization And Mineral Deposit Model In Lazihe District Fusong Country Of Jilin Province

The study area is located in the northeast of Fusong county Jilin province and Administrative division of Lushui town. It was not yet study on the regional gold deposit. The study area is located in the Mongolia plate and Zhongcao ancient land transfer belt and on the Zhongcao ancient land side.That is on the northeast Zhongcao paraplatform, Liaodong uplift, Tiding-Jingyu station arch.The main structure in the area is the northeast Erdaosonghua River fault zone and Sidaoliuhe-Wudaoliuhe river ductile shear zone, and followed by near east-west, north east fracture. The formation mainly is shell under rocks and intrusive rocks of the Archean-Proterozoic. Structural comparison of development is conducive to the formation of the gold deposits.In this paper, through the analysis of geological materials, it is summed up ore controlling factors, mineralization (temperature and pressure of metallogenic conditions, genesis of deposit, surrounding rock controlling factors and enrichment regularity of gold mineralization) and gold deposit model of the regional gold deposit. The study area of gold mineralization is a complex of magmatic hydrothermal gold deposit.It is controlled by the granite, formation and rupture structure three joint,.It is a shallow and low temperature thermal type gold deposit. Metallogenic temperature is used in the auriferous quartz vein quartz inclusion homogenization temperature, metal sulfide minerals on sulfur isotopic equilibrium temperature and inclusion decrepitation temperature estimation.The ore-forming temperature is at about350℃, and gold metallogenic pressure is the use of carbon dioxide density estimation.the metallogenic pressure is0.618-1.878GPa. And summarizing the research area of the gold deposit metallogenic model and descriptive geometry model, it is in the region of gold deposits in the study provides certain reference significance.
