黔西南地区是中国西南低温成矿域中卡林型金矿最重要的矿化集中区,由于该地区金的粒径极小,难以构成自然重砂异常,故不能直接运用自然金矿物来指示寻找黔西南的卡林型金矿。在贵州省矿产资源潜力评价项目的工作过程中,对黔西南地区的自然重砂矿物特征进行了较为系统的研究,发现采用细粒黄铁矿(载金矿物)、砷矿物(伴生矿物)、锑矿物和汞矿物的自然重砂组(综)合异常对寻找黔西南地区的卡林型金矿具有一定的指导作用和找矿意义。
黔西南地區是中國西南低溫成礦域中卡林型金礦最重要的礦化集中區,由于該地區金的粒徑極小,難以構成自然重砂異常,故不能直接運用自然金礦物來指示尋找黔西南的卡林型金礦。在貴州省礦產資源潛力評價項目的工作過程中,對黔西南地區的自然重砂礦物特徵進行瞭較為繫統的研究,髮現採用細粒黃鐵礦(載金礦物)、砷礦物(伴生礦物)、銻礦物和汞礦物的自然重砂組(綜)閤異常對尋找黔西南地區的卡林型金礦具有一定的指導作用和找礦意義。

Southwestern Guizhou is the most important mineralization concentration area of Southwest China low temperature metal?logenic domain with micro-disseminated gold deposits. However, due to the extremely small particles of gold, it is difficult for gold to form natural heavy mineral anomalies, and hence the natural gold method cannot be applied in the direct search for such micrograined type gold deposits. The authors made a systematic study of the characteristics of natural heavy minerals in southwestern Guizhou. Dur?ing the implementation of the mineral resource potential assessment project in Guizhou Province by the Natural Heavy Mineral Re?search Group, the authors found that anomalies of such natural heavy minerals as micro-fine grained pyrite (auriferous mineral), arsenic minerals (associated minerals) , antimony minerals and mercury minerals are helpful to finding this type of gold indirectly.
