摘要
长江中下游成矿带在矿产资源上具有巨大的潜力,从目前来看探明资源已开采殆尽,因此应当将重心放在深部地带。地下500m～1000m属于浅中深部地带,该部分区域最为主要的矿产资源是铜和铁,其中根据预测铜矿资源可达到1000万吨以上,铁矿资源可达到10亿吨;而在地下1000m～2000m属于深部地带,该部分区域超大型矿床资源潜力区众多,当前预测数量可达到约15处。在长江中下游成矿深部区域进行资源勘探主要集中在大型矿床的深部及外围、中新生代盖层的覆盖区这两块,除此之外对冷门区域进行新矿种的挖掘同样具备前景。
The metallogenic belt in the middle and lower reaches of the Yangtze River has great potential in mineral resources. At present, the proven resources have been exhausted, so we should focus on the deep zone. 500 m ～ 1000 m underground belongs to the shallow-middle-deep zone, and the most important mineral resources in this subregion are copper and iron. According to the prediction, the copper resources can reach more than 10 million tons, and the iron resources can reach 1 billion tons; while 1000 m ～ 2000 m underground belongs to the deep zone, there are many potential areas of super-large deposits in this subregion. The quantity can reach about 15. Resources exploration in the deep metallogenic area of the middle and lower reaches of the Yangtze River mainly concentrates on the deep and peripheral parts of large deposits and the covering areas of Mesozoic and Cenozoic caprock. In addition, the mining of new minerals in Lengmen area also has prospects.
