摘要
甘肃省加木龙沟金矿位于夏河—合作印支—燕山期金锑成矿带上,与夏河加甘滩超大型金矿毗邻,且与其有一致的成矿地质条件。加木龙沟金矿经1∶1万土壤测量,共圈出7个综合异常,主要异常元素为Au、Sb、As,共划分出4个金矿带,圈定出金矿体67条,锑矿体4条。金矿体呈似层状、透镜状赋存于三叠系下统隆务河组岩屑长石砂岩中,受NNW向构造蚀变带控制,金矿体沿走向和倾向变化较大,厚度0.81~32.18 m,金品位1.01×10^(-6)~18.67×10^(-6)。矿石工业类型为含砷低硫微细粒浸染型金矿石,矿床规模已达中型,但仍具有巨大找矿潜力。
Jiamulonggou gold mine is located in the Indosinian-Yanshanian period gold antimony mineralization belt in Xiahe-Hezuo. Gold deposit mainly occurs in the Triassic lithic arkose and is controlled by NNW direction tectonic alteration zone. Ore deposit has reached medium-size in scale, but still has a great potential for prospecting. The author has made an analogy with the gold exploration results of Jiagantan which is adjacent to this region, done a comprehensive study of ore deposit geological characteristics, summarized the ore genesis and prospecting indications, and put forward the prospecting directions for further exploration through the mining geological exploration.
