Kongyu Gold Mining Area is located in the northern margin of the Sichuan-Yunnan tectonic belt. This area has gone through two large tectonic cycles of Mesoproterozoic, Neoproterozoic and Phanerozoic. The strata are accompanied by a large number of tensile cracks, shear cracks and microfissures. The voidage, permeability and transitional effect of the rock are increased, and the transformation between surface water and groundwater is enhanced. On the other hand, tectonic movement controls the distributions and allocations of elements in the earth's crust, resulting in directional geochemical changes in crustal materials and rules. Driven by the tectonic force, the elements are reallocated. The ion content and ion compressibility of those elements increase and decrease inversely. The manifestations of rocks and minerals under directional pressure can be characterized by the flow and puncture of plastic minerals and the fragmentation of hard and brittle minerals. In the process of leaching, the pollutant elements precipitate from the deposits of different granular ores, and most are absorbed by the soil column; thus, the mass fraction of polluting elements in the soil column obviously increases. The variability is the largest when the leachate passes through the fine ore. The rate of change of the element mass fraction from high to low is Ni, Zn, Cu, Cd, Pb, As and Cr. A small part migrated from the soil column to the collection fluid, and the leaching effect is related to the rate of change of soil mass fraction, the ion radius of elements and the compressibility.

空余金矿区位于川滇构造带北缘。该地区经历了中元古代，新元古代和生元古代两个大的构造周期。地层伴有大量的拉伸裂缝，剪切裂缝和微裂缝。岩石的孔隙度，渗透性和过渡作用增加，地表水与地下水之间的转化得到增强。另一方面，构造运动控制着地壳中元素的分布和分配，从而导致地壳物质和规则的定向地球化学变化。在构造力的驱动下，元素被重新分配。这些元素的离子含量和离子可压缩性反比增加和减少。岩石和矿物在定向压力下的表现可以通过塑性矿物的流动和刺穿以及坚硬和脆性矿物的破碎来表征。在浸出过程中，污染物元素从不同粒状矿石的沉积物中沉淀出来，大部分被土柱吸收。因此，土壤柱中污染元素的质量分数明显增加。当渗滤液穿过细矿时，变异性最大。元素质量分数从高到低的变化速率是Ni，Zn，Cu，Cd，Pb，As和Cr。一小部分从土壤柱迁移到收集液中，其浸出效果与土壤质量分数的变化率，元素的离子半径和可压缩性有关。
