摘要
青海省叉叉龙洼北地区地处东昆仑多金属成矿带,满丈岗印支期金、银、铜、铅、锌(钨、铋)成矿亚带。该地区综合地质条件及各类异常特征,显示出具有较好的多金属找矿潜力,1∶5万水系沉积物测量在矿区圈定出以W、As、Au、Pb、Zn为主的综合异常3处,圈出3条矿化带、11条矿体和1条含Au石英脉,取得了较好的找矿突破;1∶5万磁法测量工作圈出磁异常6处,通过异常检查,圈出4条矿化带、1条铜金矿体。研究表明,本区具有优越的成矿地质条件、物化探异常发育,且已发现了较好的多金属矿找矿信息,充分展示出本区具有较大的找矿潜力,为下一步找矿勘查工作提供了依据。
The norther Chachalongwa polymetallic deposit is located in eastern Kunlun metallogenic belt and Indosinian-Manzhanggang Au, Ag, Cu, Pb, Zn(W, Bi) sub-metallogenie belt and the geological and metallogenic condition is superior. Integrating the geological conditions with the anomalons characteristics, the study shows good prospecting potential for polymetallic deposits. The 1∶50000 scale stream sediments survey dominated 3 integrated anomalies of W、As、Au、Pb、and Zn. Through anomaly verification, 3 mineralized zones, 11 ore(mineralized)bodies and 1 Au bearing quartz vein are delineated with good prospecting results. There are 6 magnetic anomalies were detected by 1∶50000 magnetic survey, 4 mineralization zones and 1 copper-gold orebody were circled by anomaly inspection. From the above, the favorable metallogenic conditions, developed geochemical anomalies and informative clues of Ag-polymetallic ore prospecting fully show that the area has great prospecting potential.
