摘要:
达热尔地区位于东昆仑成矿带东段，地球化学景观区属于柴达木盆地南缘中深切割山地草原—草甸(高寒)地带景观区，以往1∶20万、1∶5万水系沉积物测量均未圈出金异常。经开展1∶2.5万水系沉积物测量，圈出2处以金为主的综合异常HS4、HS5，结合研究区地质?卣鳎衔?处综合异常具有较好的找矿潜力。经查证，圈定了矿带7条，矿体6条，实现了该地区的找矿突破。结果表明，1∶2.5万水系沉积物测量在高原特殊地球化学景观区找矿具有较好的应用价值。

Abstract:
The Dareer area is located in the East section of East Kunlun ore belt.The geochemical landscape belongs to deep-cut upland grassland-meadow(high and cold) zone landscape on the southern rim of Qaidam Basin.The previous 1∶200 000 and 1∶50 000 stream sediment survey both failed to delineate gold anomaly.After the 1∶25 000 stream sediment survey,2 gold-dominated comprehensive anomalies HS4,HS5 are delineated.According to their geological characteristics,it is deemed these 2 comprehensive anomalies have great prospecting potentials.Verification shows that 7 ore belts and 6 ore bodies are delineated,achieving prospecting breakthroughs in the area.The results show that 1∶25 000 stream sediment survey has good application effect in plateau special geochemical landscapes.
