内蒙古幸福村金矿成矿特征及找矿方向

Geological Features and Prospecting Orientation of Xingfucun Gold Deposit in Inner Mongolia

幸福村金矿位于内蒙古化德县境内,大地构造位置处于华北地台北缘白云鄂博裂谷带之东段。含金脉体分布于矿区中部,主要赋存于白云鄂博群比鲁特组千枚岩中。通过总结矿区地质特征,研究矿区地、物、化等资料,分别从见矿部位的地球化学特征、地球物理特征、矿体的近似等距性及邻区典型金矿对比等4个方面进行分析,认为在平面上,矿体呈近似等距性分布规律,在垂向上,矿体的形态具有膨大缩小和尖灭再现的特点。结合矿区实际,指明了矿区下一步找矿方向,应以寻找石英脉—蚀变岩型金矿体为主。

Xingfucun gold deposit of is located in Huade County of Inner Mongolia,the tectonics of which locates in the east of north edge of North-China Platform, Baiyunebo rift belt.The gold vein distributes in the central area, and mainly exists in the Bayan Obo group Bilute fabric phyllite.The geochemical features,geophysical features, approximately equal in distances of orebodies and contrast of typical gold deposit in adjacent regions are studied in this paper,through summarizing geological characteristics of mining area, doing research in geological, physical and chemical data.The results show that ore body shape the approximately equidistant distribution from the plane,and from the vertical,ore body shape characteristic of expansion and contraction,pinch reproduction. Combining actual conditions of mining area,quartz vein altered rock type gold orebody should by the main prospecting direction in future.
