| 摘 要： | 葫芦沟金矿床矿体主要呈咏状和透镜状产出；矿石矿物主要为黄铁矿，其次为方铅矿、黄铜矿和闪锌矿，脉石矿物主要为钾长石和石英；矿石结构为他形-半自形、自形晶粒和压碎结构，矿石构造以团块状和碎裂状为主；矿区近矿围岩蚀变类型有硅化、钾化、黄铁矿化和绢英岩化、通过对矿区稀土元素特征进行分析，认为葫芦沟金矿床物质来源于太古宇太华群，属于赋存于古老变质岩中的中低温石英咏-破碎蚀变岩型金矿床.

| Abstract: | The ore-forming characteristics of Hulugou gold deposit was studied based on analyzing of its metallo- genic geology background and geology features.It is found that the orebodies of Hulugou goht deposit mainly occurred as the vein and lenses;0re minerals are mainly pyrite and galena,chalcopyrite,sphalerite,gangue minerals are mainly potassium feldspar,quartz;Ore texture mainly are xenomorphic and hypidiomorphic,euhcdral crystal and crushing structure,ore structure are dominated by massive and cataclastic structures;Wallrock alterations near the orebody are silicide,potassium,pyritization and silk lithification.Besides,through the analysis of characteristics of rare earth elements in mining area,the article comes to the conclusion that the material of＇ Hulugou gold deposit is derived from Taihua Group,Archaeozoic erathem,which belongs to the occurrence in the old metamorphic rock of middle to low temperature quartz-vein type and fractured altered rock-type gold deposit. |
