摘要
矿床赋存于燕山期黑云母花岗岩中,北西向断裂构造是本区最重要的控矿构造,石英脉沿北西向构造贯入,金属矿物呈网脉状、细脉浸染状分布于裂隙中,形成品位较低但分布较均匀的矿体,矿体整体呈脉状,矿物共生组合由黄铁矿、黄铜矿、辉钼矿及少量闪锌矿、方铅矿等组成。通过对含矿岩系、构造及矿体的地质特征进行分析研究,确定了矿床成因。
Deposit occurrence in yanshanian biotite-granite,northwestern fracture structure in this area is the most important ore-controlling structure,quartz vein penetrates along the northwestern structure,metal minerals distributes in fracture in net vein style and disseminated fine vein style,forms the ore body of low grade but more homogeneous distribution.Whole ore body shows vein,Mineral symbiosis combination combined pyrite,chalcopyrite,molybdenite with a small amount of sphalerite,galena,etc.Through analyzing the ore-hosted rock series,structure and the geological characteristics of ore body,the deposit origin is determined
