摘要
本文在区域成矿条件的基础上,着重对黔东南下江群深部金矿进行了预测,预测依据:矿床模式对比,找矿矿物学,成因矿物学,化探异常,包裹体,金矿化三度空间,δO^(18)稳定同位素,邻区湖南金矿床。金矿成因类型为变质热液型,金矿矿床类型为细脉浸染型或细脉浸染硫化物型。明确黔东南下江群深部金矿找矿方向。
The gold mineralization in Xiajiang Goup in southeastern Guizhou is related to meta-morphic fluid and the gold deposits can be divided into the following types: veinlet-dissem-inated deposit, turbidite-hosted, and tectonoclastic-alteration rock. Based on the studies of regional metallogenic conditons of gold deposits, the metallogenic prospect of gold deposits in Xiajiang Group in southeastern Guizhou has been calculated and the factors of metallogenic prognosis are the comparison of metallogenic model,prospecting and genetic mineralogy, the anomalies of geochemical prospecting, the distribution of gold mineralization in tri-dimensional space, the values of δ18O and study results of gold deposits in adjacent areas.
