| 摘 要： | 近年来对新疆某金矿区戈壁覆盖条件下开展了不同类型金矿床进行吸附相态汞、卤素(Cl)、热释CO_2和电化学(Ks)金的找矿试验研究,对石英脉型金矿床和破碎带蚀变岩型金矿床试验结果,初步发现矿体上部壤中Au、Ag、Cu、Zn、Pb、As、Sb一般组合异常差。而壤中的吸附想态汞、Cl、热释CO_2和电化学在矿体前缘及上盘均有较好的异常,特别在厚层洪积物覆盖区,这些新方法亦能反映出盲矿体的异常。

| Abstract: | We have carried out a series of experimental studies for gold prospecting by using with absorbed state mercury ,halogen (Cl).thermal released CO2 and electrochemistry (Ks) methods in various types of gold deposits with gobi covering condition in Xinjiang. The experimental results got from quartz vein type and fractured zone altered rock type gold deposits show that the general composite anomoly of the elements Au,Ag, Cu,Zn,Pb,As and Sb in the soil above gold ore body is not obvious. But the anomolies of absorbed state Hg. CI ,thermal released CO2 and electrochemistry in the soil of leading edge or hanging wall of the ore body show clearer. These new methods can reflect especially the anomoly of blind ore bodies in the area covered by thick proluvium. |
