| 摘 要： | 通过对在大兴安岭北部森林沼泽—冻土景观区的1:5万水系沉积物测量方法技术的研究,发现以水系沉积物中较粗粒级的碎屑(-10～+60目)作为采样介质,可有效地排除有机质的干扰,强化异常;并提出在水系沉积物不甚发育的地区,以水系沉积物为主,辅以网格法土壤测量,则能更有效地提高找矿效果。 |

| 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. |
| Keywords: | weathering migration and enrichment of elements stream sediments soil grain size organic matter |
