In a selected test area within the Beishan arid desert gobi relict mountain landscape region of Gansu Province, 1:50000 stream sediment survey and soil survey were conducted. A comparative study shows that both methods can obviously and completely delineate ore-related anomalies. In the area of alternate relict mountain and eroded gobi, soil survey can cover larger area and have higher anomaly intensity than stream sediment survey; however, soil survey needs larger amount of work than stream sediment survey. In practice, the choice of proper methods should be based on the development extent of streams and other factors in the work area.
