辽宁省葫芦岛市王家沟钼多金属成矿条件分析

Analysis of metallogenic conditions of Wangjiagou molybdenum polymetallic deposit in Huludao City,Liaoning Province

矿区西南侧为青龙-锦西深大断裂与寺儿堡-营盘基底断裂交汇处,主要构造形式为断裂构造。主要发育的断裂构造走向为北东向及北西向,北东向构造为主要控矿构造。成矿区域为八家子-杨家杖子岩浆热液多金属成矿带北东部的虹螺山花岗岩体南侧边缘。其中次级构造内蚀变矿化作用较强,多产于燕山期细粒花岗岩内。找矿前景极佳。

The southwest of the mining area is the intersection of Qinglong Jinxi deep fault and sierbao Yingpan basement fault.The main structural form is fault structure.The main developed fault structure trends are northeast and northwest,and the Northeast structure is the main ore controlling structure.The metallogenic area is the southern edge of hongluoshan granite body in the northeast of Bajiazi Yangjiazhangzi magmatic hydrothermal polymetallic metallogenic belt.Among them,the alteration mineralization in the secondary structure is strong,which mostly occurs in Yanshanian fine-grained granite.The prospecting prospect is excellent.
