金川矿区深部成矿规律与找矿方向

Minerogenetic law and exploration orientation in Jinchuan mine deep area

我国有色金属矿山大部分已进入开采的中晚期 ,许多主要的有色金属基地正面临严重的资源危机。笔者通过在金川所做的研究发现 ,金川矿区深部矿化富集与成矿后的构造关系密切 ,构造变质热液使部分初始成矿物质产生活化 ,并在褶皱、断裂的低压扩容部位再次聚集。经钻孔验证 ,发现了新的工业矿体 (相当于一个中型镍矿 ) ,对今后找矿的方法和有色矿山缓解资源危机有参考价值。

Most of nonferrous metals mines in China have entered into middle and later stage, and many main nonferrous metals bases are faced with serious resource crisis. According to the research work in Jinchuan, it has been found that the mineralization and enrichment in deep portion of Jinchuan mine area is closely associated with the post minerogenetic structure, and the tectonic metamorphism hydrothermal makes part of the primary minerogenetic materials active and reaccumulated at the low press and expanding portion of the fold or fault. A new industry orebody (enqual to a medium scale nickel mine) has been discovered by drilling test hole and verification, which put forward explorating orientation in the future and effective way to alleviate resource crisis of nonferrous metals mines.
