In light of the fact that large amounts of aeolian sands exist on the surface of the Malimuwuka area in Dulan County,Qinghai Province,1∶25 000 geochemical survey was selected for early geochemical exploration to avoid its influence.The sampling point density was 20~32 points/km₂.The sampling medium is sharp-cut rock debris material,medium coarse sand and remnant slope wash.The sampling granularity is -10 mesh to +60 mesh.Based on the analysis of element content,enrichment dispersion and combination characteristics,6 geochemical exploration anomalies were delineated and 1 prospecting prospect was determined.Practice shows that 1∶25 000 geochemical survey has good application value in the exploration of the alpine plateau landscape in East Kunlun.
