金川矿区深部找矿方向探讨

DISCUSSION ON EXPLORATION ORIENTATION IN THE DEPTH OF JINCHUAN MINING AREA

在金川所做的研究表明,金川矿区深部矿化富集除与岩体有关外,还与成矿后的构造—热液关系密切,构造—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),提出了今后找矿的方向和有色矿山缓解资源危机的有效途径。

The most non-ferrous metals mines in China have entered into the middle and later stage of development and faced with serious resources crisis. Based on research works, it has been found that mineralization and enrichment in depths of the Jinchuan mining area are closely associated with the post-mineralization structure. Tectonic-hydrothermal events made parts of the initial mineralizing materials active and re-accumulate at the low pressure and expanding portions of the fold or fault. A new industry orebody equal to a medium scale nickel mine testified by drilling holes has been discovered. Those provide an exploration orientation for the future for Jinchuan Mine, and effective way to alleviate resources crisis of non-ferrous metals mines.
