| 摘 要： | 本文在区域成矿地质背景的基础上，详细论述了西直格庄金矿的控矿断裂特征、矿体地质特征和矿石特征及矿物成分等，并划分出4个蚀变矿化阶段。通过矿化类型、矿物组合等研究确定西直格庄金矿成因类型属于交代—重熔岩浆期后中低温热液沿破碎带交代型金矿床。通过金矿床成矿规律的分析进一步提出地层、岩性、构造、围岩蚀变等方面是该金矿深部及外围的找矿标志及方向。

| Abstract: | On the basis of regional metallogenic setting, the ore-controlling faults features of Xizhigezhuang gold deposit, its geological feature of orebody, feature of ores, mineral composition are described in detail, meanwhile, its alteration stage also can be separated four stages. Based on research of mineralization type, mineral assemblage of Xizhigezhuang gold deposit,determined its genetic type belongs to remelted postmagmatic epithermal-mesothermal pyrometasomatic deposit in fracture zone. Furthermore, based on the analysis of metallogenic regularity in Xizhigezhuang gold deposit, its stratum, lithology, rock structure, wall-rock alteration are proposed as the criteria and direction of prospecting in the deep and periphery in Xizhigezhuang gold deposit. |
