Abstract Based on a study of the techniques for 1:50000 stream sediment survey in forest swamp frozen soil landscape area of northern Da Hinggan Mountains, the authors have discovered that the adoption of relatively coarse grained fragments (-10~+60 mesh) in stream sediments can effectively eliminate the interference of organic matter and strengthen the anomaly. It is also held that in areas where stream sediments are not well developed, the utilization of stream sediment survey with the help of grid soil survey can obviously raise the ore prospecting efficiency.
