| 摘 要： | 尖尼—桑坝一带自开展1∶20万区域化探以来,先后进行了异常查证,发现了众多的金矿床点。本文探讨了该区金地球化学特征,特别是1∶5万水系沉积物测量、1∶1万土壤地球化学测量,显示出Au异常规模大、峰值高、浓度分带好,Au、As、Ag、Hg、Sb等组合异常套合好的特征。采用土壤测量浓缩异常源、缩小找矿靶区,发现了金矿体,找...

| Abstract: | Many gold deposits and occurrences have been discovered through the examination of anomalies outlined by 1：200 0000 regional geochemical prospecting in Jianni-Sangba area.This paper discussed the gold geochemistry feature of this area.The results of 1∶5 0 000 stream sediment survey and 1∶10 000 soil survey show that the Au anomalies is characterized by large area,high peak and fine zoning of concentration,good anomalous association of Au,As,Ag,Hg,Sb.The soil survey was employed to reduce the exploration target,and the ore body has been determined.By comparison and analysis,it is clear that the systemic prospecting in this area should be the main method,by 1∶50 000 stream sediment survey for outlining anomalies,and 1∶10 000 soil survey for reducing target. |
