摘要
磨沟金矿床赋存于中元古界熊耳群安山岩中,位于马超营区域性断裂带上。区内北西向、北东向断裂构造非常发育,沿构造蚀变带铅锌银等多金属异常富集特征明显。矿区出露地层为中基性与中酸性熔岩互层的熊耳群鸡蛋坪组。熊耳群火山岩中微量元素和主要元素含量间存在较好的相关性。金的分布有较强的规律性,金高背景-异常带的分布受区内北西-南东向断裂构造线控制比较明显。根据已施工工程验证的化探异常资料,认为本区深部金、银和铅、锌等多金属矿找矿前景很好。
The Mogou gold deposit hosted in andesite of the Middle Proterozoic Xiong＇er Group, is located within the regional Machaoying fault zone. The NW and NE trending faults are well-developed in this area. There are many significant Pb-Zn-Ag polymetallic anomalies along the structural alteration zone. Strata exposed in the area are mainly interbedded basic and acid lava, Jindanping Formation, Xiong＇ er Group. There is a good correlation between the content of the main elements and trace elements in Xiong＇er Group. The distribution of gold has strong regularity, and gold high background anomaly zone is controlled by NW-SE faults obviously. Examined geochemical anomalies suggest there is good prospecting ofAu-Ag-Pb-Zn polymetallic ore in the deep part.
