| 摘 要： | 大兴安岭北部为典型的森林沼泽景观区,勘查地球化学找矿方法在该区找矿工作中起到了重要作用,这一特定的景观内大区自然环境相同,而局部地质、地貌条件、植被发育程度、风化程度等各有差异,必将影响工作方法的选择及其应用效果.通过富克山地区1/5万水系沉积物测量及后期查证的工作,以生产与试验相结合,对水系沉积物测量及后期土壤地球化学测量工作方法进行了探索研究,取得了较好的应用效果.认为富克山地区应属中低山森林沼泽亚景观区,水系沉积物测量采样介质可以采用细砂、粉砂、岩屑,野外样品初加工方法为水筛,野外样品初加工粒级为-10+60目.二级查证1/万土壤地球化学(剖面)测量,采样层位为B层,介质以褐黄色、土黄色土壤为主,初加工粒级为-40目,初加工方法为干燥后过筛.

| Abstract: | The exploration geochemical methods play an important role in northern Daxinganling region, which presents a typical swamp forest landscape. Although sharing the same natural environment in general, the local geology, geomorphology, development of vegetation and degree of weathering are various. This may influence the choice of working methods and their application effects. Based on the research of stream sediment and soil geochemical survey in 1：50000 scale and later verification, it is concluded that the Fukeshan area belongs to medium-low mountainous swamp forest landscape. Samples of stream sediment survey can adopt fine sand, powder sand and rock debris. The pretreating method for field samples is water sieve, with size fraction of -10 to ＋ 60 mesh for preliminary processing. Sampling is carried out in Horizon B for the secondary verification to 1：10000 pedogeochemistry survey. The samples are composed of mainly brown and earthy yellow soil, with preliminary processing size of -40 mesh, sorting after drying. |
