内蒙古闫家村金矿地质特征及找矿远景预测

内蒙古丰镇市闫家村金矿区位于内蒙古中部,处在华北陆块北缘大青山金银多金属成矿带上,隶属晋冀蒙EW-NEE向高级变质岩区内,是近年来新发现的构造蚀变岩型金矿体。通过分析闫家村金矿地质特征,对其矿床成因、找矿标志以及成矿远景进行了研究,认为该区具有寻找与酸性岩浆岩侵入活动有关的斑岩型、接触交代型和热液型金银铜钼多金属矿床的良好前景。

Geological characteristics and prospecting potential pediction in the area of Yanjia village in Fengzhen, Inner Mongolia

The Yanjia Village gold project of Inner Mongolia is located in the middle of Inner Mongolia, where is the Daqingshan gold and silver polymetallic metallogenic belt at the northern margin of the North China landmass belonging to EW-NEE senior metamorphic zone strenching towards to Shanxi, Hebei and Inner Mogolia in China. It is a new discovered gold deposit of tectonic altered rock type in recent years. Based on the analysis of the geological characteristics of Yanjia village gold deposit, this paper has studied the genesis, prospecting sign and prospecting potential prediction of the deposit, and has concluded that this area has a good potential for finding porphyric, contact metasomatic and hydrothermal Au-Ag-Cu-Mo polymetallic deposits which are related to acidic magmatic intrusion.
