东秦岭包括陕南、予西南、鄂北广大地区,金矿资源十分丰富,点多面广。据初步统计,全区共有各类金矿床矿点及矿化点二百多处在全国占有重要地位。该区古老变质岩地层出露广泛,某些地层含金丰度偏高,构造复杂,秦岭纬向褶断带具有长期继承活动特征,各类岩浆岩分布广泛,变质作用及混合岩化作用十分强烈,对金矿成矿条件十分有利,金矿床具有显著的层控性质。 (一) 按照我国著名大地构造学家陈国达教授所创立的“地洼”学说,该区在大地构
East Qinling, including southern Shaanxi, to the southwest, northern Hubei vast areas, gold resources are very rich, point wide. According to preliminary statistics, there are altogether more than 200 ore deposits and mineralization sites of various gold deposits in the region occupying an important position in the country. The ancient metamorphic strata in this area are exposed extensively, with high gold abundance in some strata and complex structures. The zonal fold belt in the Qinling Mountains has long-term inheritance characteristics, and various types of magmatic rocks are widely distributed with metamorphism and mixed rock formation. Strong, very favorable for gold mineralization conditions, gold deposits have a significant layer control properties.
