摘要
对长江中下游成矿带内主要矿产地和远景区进行分析,结合近年来找矿工作的进展,提出长江中下游地区中深部资源潜力巨大,浅中深部(地下500m～1000m)铜的资源潜力可望达到1000万t以上、铁10亿t,其中大型—超大型矿床(区)7处～10处。深部(地下1000m～2000m)具有10处～15处大型—超大型矿床资源潜力区的可能。可通过深部找矿勘查工作,在已知大型矿床深部和外围、中新生代盖层覆盖区及新层位、新类型地区等地,实现深部"第二空间"的找矿突破。
Based on the analyses of the major deposit locations and prospective districts within the metallogenic belt, in combination with the recent development in fields of mineral exploration, the authors pointed out that the area was of huge potentiality for deep resources, in shallow deep section （500m - 1 000m underground）, the copper resource potential reached over 10 million tons, iron reached one billion tons, in which, the large-sized to super large-sized deposits （ore districts） numbered seven to ten sites; in moder- ate deep section （ 1 000m ~ 2 000m underground）, ten to fifteen sites of large-sized to super large-sized resource potential areas were possible. Through deep investigation and exploration, the authors concluded a realization of deep prospecting breakthrough along the deep parts and periphery of the known deposits, capping overburdens of Mesozoic and Cenozoic Eras and other new horizons and new kind of areas.
