一、矿区地质及矿床水文地质条件(一)矿区地质简述1.矿床的地质位置:根据已往地质文献记载,前撮落钼矿床位于中朝古陆的北部边缘。矿区之山脉位于老张广才岭南部之西侧及大黑山脉南端之东侧,多为低山及丘陵地形。本区域主要构造为北北东一南南西方向,沿此方向出现大面积的花岗岩及其他火成岩,前撮落钼产于斜长石花岗岩中,钼矿床生成受断裂构造之控制,钼矿细脉则填充于裂隙中或与石英细脉相伴生。
I. Geological Conditions of Mining Areas and Hydrogeological Conditions of Mineral Deposits (I) Brief Geology of Mining Areas 1. Geological Location of Deposits: According to the records of geological records in the past, the former tributary molybdenum deposit is located on the northern edge of the ancient North China. The mountains of the mining area are located on the west side of the southern Changguangcailing Ridge and the east of the southern end of the Dahei Mountain Range, mostly low mountainous and hilly terrain. The main structure of this area is north-north-east-south-south-west direction. Large-area granite and other igneous rocks occur in this direction. The former tributoma molybdenum is produced in plagioclase granite. The molybdenum deposit is controlled by fault structure. Fill in the cracks or associated with the quartz vein.
