摘要
受燕山中晚期地质构造运动和岩浆活动的影响 ,在中酸性侵入岩体与钙镁碳酸盐岩外接触带 ,大银山金矿体呈扁平透镜状产于侵入体的舌状端部。是中低温热液型含金矽卡岩矿床。研究其成矿地质条件和控因素 。
Affected by geotectonic movement and magmatic activities in middle-late Yanshanian Period,the ore body of Dayinshan gold deposit is located in the exocontact of middle-acidic intrusive rock body and Ca-Mg-Carbonate rock,at the tip of the intrusive, occurring in flat lenticulat shapes. It belongs to gold-bearing skarn ores of middle-low temperature jucbrothermal type. research on the geological conditions of its.nineralinzation and the mineralization-controlling factors will have great significance for ore prospecting and mineralization forcast.
