冲积砂金的纯度习惯上是判定其化学机理的重要标准,是砂矿建造性质和主要成矿成分的信息源。以前,有许多研究项目是以假设冲积金内核纯度与内生金纯度相吻合为前提来讨论砂矿矿化原生源的。通过研究冲积金的化学机理表明,这种假设是没有根据的。我们以三条河流流域作为研究的对象,其中每一条河流都是流经金——硫化物热液矿化地区的。碎屑金原生源的浸蚀性成分在这里实质上是各种各样的,这一点正好反映了冲积金
The purity of alluvial gold has conventionally been used as an important criterion for determining its chemical mechanism and as a source of information on the nature of the ore deposits and the major metallogenic components. Previously, many research projects discussed the mineralization of primary sources of sand based on the assumption that the purity of the alluvial core coincides with the purity of the gold. By studying the chemical mechanism of alluvial gold shows that this assumption is unfounded. We take the three river basins as objects of study, each of which flows through the gold-sulphide hydrothermal mineralization area. The erosive constituents of the detrital gold source are virtually all kinds of here, which exactly reflects the alluvial gold
