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.
