辽宁省海城市石柱沟金钼矿(化)体地质特征及找矿方向

Geological Characteristics and Prospecting Orientation of Shizhugou Golden Deposit of Haicheng city Liaoning province

辽宁省海城市石柱沟金钼矿受花岗岩接触带控制。金矿床类型为含金石英脉型,矿石矿物成分简单,金属矿物为黄铁矿、方铅矿、闪锌矿、自然金,脉石矿物为石英,矿石结构为交代结构、充填结构、包裹结构,矿石构造为块状构造、侵染状构造。依据矿物组合、结构构造及围岩蚀变特征,初步认为金矿床属于中低温热液裂隙充填交代型。钼矿(化)体为细脉侵染型,金属矿物为辉钼矿,围岩蚀变发育,其远景有待于进一步评价。金钼矿的发现为该区地质找矿工作指明了方向。

Shizhugou gold-- molybdenum deposit is obviously controlled by granite contact zone. The golden deposit is the type of gold--bearing quartz vein, in which ore mineral composition is simple. Metal- lic minerals are Pyrite, galena, sphalerite, native gold and gangue mineral is quartz. The ore texture in- cludes metasomatic, filling, wrapped texture, and the ore structure includes massive, infection--like structure. The golden deposit is initially considered as the type of middle and low temperature fissure fill- ing and replacement by mineral assemblages, structure and texture, and wall rock alteration features. There is veinlet--disseminated type in the molybdenum mineralized body, in which Metallic mineral is mainly the molybdenite, and Wall rock alteration development. The discovery of the gold--molybdenum deposit type indicates the orientation of geological prospecting work for the area.
