| 摘 要： | 水系沉积物和土壤采样分析研究表明, 在研究区地球化学找矿工作中可采用两者相结合的采样方法。水系沉积物样品过筛粒级为- 10～ + 60目, 其中- 10～ + 20目和- 20～ + 40目粒级样品比较发育, 含量较高, - 40～ + 60目粒级样品含量最低, - 60目样品含量上下波动较大。样品中Au、Bi 和Sn含量变化大, 变异系数在各粒级中分别为0.41～1.41、1.84～2.49和1.40～1.50, 其他元素在各粒级中变异系数为0.31～0.94, 含量变化较小。土壤测量发现, 在B层发育部位采集B层中部土壤, 在B层不发育地段采集B +C层土壤样品, 能较好反映异常。元素含量从浅到深有增加趋势, 异常强度有所变化, 但对发现异常没有影响。

| Abstract: | The study of stream sediment and soil sampling indicate the two methods can be combined in geochemical prospecting. The sieving grain sizes of stream sediments ranging - 10～60 mesh, - 10～20 and - 20～ 40 mesh develop well with high contents, - 40～60 mesh has the lowest content, and the content of - 60 mesh fluctuates greatly. Au, Bi and Sn are greatly changed in content, variation coefficients are 0.41～1.41, 1.84～ 2.49 and 1.40～1.50, respectively, and the other elements pvariation coefficients are from 0.31 to 0.94 with little change. The soil survey shows that the reflecting abnormity preferably is in collectmiddle part of Blayer soil where Blayer grows well and in the collection of the B +C layer soil where Blayer poor in growing. The contents of elements increase from shallow part to deep, the intensity of abnormity also changes, but do not effect to discover abnormity. |
