| 摘 要： | 重点对辽西牛家店金矿床区域成矿地质背景、矿区及矿床地质特征进行了分析研究,并探讨了矿床成因。研究表明,牛家店金矿床矿区范围内北东向断裂构造控制着区内2条金矿体及蚀变破碎带的产状、形态和规模,黄铁矿化、硅化、磷酸盐化、绿泥石化等围岩蚀变与金成矿关系密切,可作为直接找矿标志。综合分析认为,牛家店金矿床为中低温变质-岩浆热液型金矿床。

| Abstract: | The paper analyzed the regional mineralization settings and the geological characteristics of the mining area and deposit of Niujiadian Gold Deposit in western Liaoning province,and discussed the deposit genesis.The study shows that the NE trending fault structure in the domain of Niujiadian Gold Deposit controls 2 gold orebodies and the occurrence,form and scale of the alteration fractured zone.Pyritization,silicification and phosphatization,chloritization and such alteration are closely related to gold mineralization and can be used as direct prospecting indicators.Comprehensive analysis thinks that the Niujiadian Gold Deposit is a mesothermal alteration-magmatic hydrothermal fluids gold deposit. |
