河北兴隆县太平村钼矿床地质特征及找矿潜力研究

Geological Characteristics and Prospecting Potential of Taipingcun Molybdenum Deposit in Xinglong County,Hebei Province

太平村钼矿床受燕山期多期次岩浆活动及构造的双重作用控制,断裂破碎带及隐爆角砾岩等是良好的赋矿部位;矿体具有膨大狭缩、分枝复合和成群成带产出的特征,近矿围岩蚀变发育,具有多期次叠加的特征;从侵入岩以及隐爆角砾岩集中分布区域为中心向四周具有“钾长石化硅化带→硅化绢云母化带→青磐岩化带”和与之相对应的“Mo→Cu、Pb、Zn(Mo)→Au、Ag”矿化,体现出“高温热液蚀变→中低温热液蚀变”的特征,在深部和外围找矿潜力巨大。

The Taipingcun molybdenum deposit is controlled by the double action of Yanshanian magmatic activity and structure.The fracture zone and concealed explosive breccia are good ore-bearing parts.The ore body is characterized by expansion and narrow shrinkage,branching and recombination,and occurrence in clusters.The alteration of surrounding rock near the ore body is characterized by multi-stage superposition.From the intrusive rock and cryptoexplosive breccia concentrated distribution area centered around"potassium feldspathization silicified belt and silicide sericitization zone-green rock lithification belt"and with the corresponding"Mo,Cu,Pb,zinc(Mo),Au,Ag mineralization,embody the"high temperature hydrothermal alteration-liquid "medium to low temperature alteration"characteristics,in the deep and periphery prospecting potential is tremendous.
