本文所涉及地区以具有许多含金砂矿为其特征,但未包括其全部基岩源.分析砂矿形成过程对寻找基岩矿床是必不可少的.面临着砂矿和金矿石(Ore gold)的粒度、数量和采样性质的明显差异,如果我们考虑了下列因素,这些差异将不难说明:a)金属的水力分选作用,b)未出露的金矿石源,c)从侵蚀至现在金属的汇集作用,d)在砂矿形成中,金属在氧化带的转变,e)砂矿中所生成的金.在复杂条件下,所有这些因素均起作用,而重要的建立起它们的顺序,以便识别对本区起决定作用的因素.
The area covered by this article is characterized by many gold-bearing sands, but does not include all of the basement sources, and analysis of sands formation is essential for the search for bedrock deposits, facing the ore and gold ore (Ore gold) If we consider the following factors, these differences will not be difficult to explain: a) hydraulic separation of metals, b) unexposed sources of gold ore, c) erosion from the present to the present Metallization of metals, d) Transformation of metals in the oxidation zone during placer formation, e) Gold generated in the placer ore. All of these factors work in complex conditions, and the order of their importance is established In order to identify the factors that determine the region.
