江西宁都县廖坑矿区钨矿地质特征及成因分析OA

By analyzing the geological conditions and metallogenic setting of tungsten deposit in Liaokeng mining area,Ningdu County,Jiangxi Province,this paper analyzes and summarizes the relationship between the structure,stratigraphy,magmatic rock,fault structure and mineralization and the genesis of the deposit.The results show that the tungsten polymetallic minerals in this area are mainly distributed in the tectonic fracture vein tungsten deposits in the contact zone of the Middle Jurassic granite.Mineralization is closely related to structure,regional tectonic movement is strong,magmatic activity is frequent,is an important tectono-hydrothermal event in the region.At the same time,the basic rock types and dissolving Spaces of alteration and ore are formed,and the hydrothermal fluids rising along the tectonic belt form ore bodies and mineralization zones.The development of NEE and NEE trending faults and fissures in the mining area provides a more favorable tectonic environment for mineralization.
