不同风化程度的矿石有不同的矿物学和化学组分特征，因而可以根据化学分析结果作定量判别。
The ores with different weathering degree have different characteristics in mineralogy and chemical composition. Therefore, they can be quantitatively distinguished according to the chemical analysis.
但由于构造活动及地表风化作用的影响，矿层在地下水的作用下，其保存情况及矿石类型形成了明显的分带性。
But due to the influence of the structural activities and weathering in the surface, under the action of underground water, the ore types and the preservation of ore seam showed obvious zoning.
三种矿石类型（原生矿、氧化—半氧化矿、风化残坡积矿）在平面上和垂向上均呈有规律的分布；
Three ore types of primary ore, oxide-semioxide ore and weathering residual deluvial ore regularly distribute in level and vertical;
