| 摘 要： | 根据青海南部绝玛拉地区1∶2.5万水系沉积物测量成果,划分出以Cu-Co、Pb-Zn-Ba以及As-Sb为主的3种元素组合类型。通过异常查证,在研究区圈定4处综合异常,在元素地球化学特征及元素组合特征分析的基础上,结合研究区成矿地质背景,确定找矿有利部位。通过槽探工程揭露,圈出矿化带2条,圈定铜矿化体4条,取得了较好的找矿效果,表明研究区具有较大的找矿潜力。

| Abstract: | According to the results of 1∶25,000 stream sediment surveys in Juemala area,southern Qinghai Province,element assemblages were divided into three species:mainly Cu--Co,Pb--Zn--Ba and As--Sb.The authors delineated four comprehensive anomalies by anomaly investigation in the study area.Based on the analysis of element geochemical characteristics and element combination characteristics,in combination with the ore-forming geological setting of the study area,we consequently identified favorable prospecting sites.By exploration engineering exposure,we have achieved good prospecting results,including two mineralization belts and four copper bodies.The results prove that there s great potential of prospecting in the study area. |
