在地球化学探矿中,特别是金属量测量,其所得结果的可靠性大都是决定于正确地选择采样方法。至于在金属量测量中广泛流行的采样方法是在疏松沉积层的最上部:即土壤或残积层中采样。在此情况下,重要的是要知道在上述沉积中,哪种颗粒级或 In the geochemical prospecting, especially the amount of metal, the reliability of the results obtained are mostly determined by the correct choice of sampling methods. As for sampling methods that are widely prevalent in the measurement of metals, they are sampled in the uppermost part of the unconsolidated sediments, ie soil or stratum. In this case, it is important to know which particle size or grade in the above deposition
