| 中文摘要: |
| 白日其利沟脑勘查区位于东昆仑中段、昆中断裂带南侧。前人根据1∶50 000水系沉积物异常开展预查工作,圈定了4处较明显的1∶10 000土壤综合异常,在AP2土壤异常区内发现了2条含金矿化带。通过系统总结1∶10 000土壤异常特征,发现Au、AS、Sb成矿元素含量高,变异系数和富集系数均较大,具有明显的聚集成矿趋势。已发现两条金矿化蚀变带,矿化体规模较小,与异常规模明显不匹配,另外还有3处土壤异常未查证。综合分析地质和地球化学特征,认为勘查区仍具有进一步找矿潜力。 |
| 英文摘要: |
| The Bairiqiligounao exploration area is located in the central part of the eastern Kunlun mountains and in the southern side of Kunlun fault zone. Previous 1∶50 000 stream sediment survey generated four soil anomalies at scale of 1∶10 000, two gold mineralization alteration zones were found in AP2 anomaly. Through systamtical analysis of these soil anomalies in the exploration area, it was found that the concentration values of metallogenic elements of Au, As, Sb are high, and concentration coefficient and variation coefficient varied greatly, which indicate that these is a trend of mineralization by these elements. The mineralized body defined by two gold mineralization alteration zones outlined in the previous investigation work is relatively small, which is obviously not match the scope of abnormal area. In addition remaining 3 soil anomalies are not verified yet. Thus, it is predicted that there is great potential for finding deposits in the Bariqiligounao exploration area in combination with comprehensive analysis of geological and geochemical data. |
