在研究不同建造类型金矿床矿石物质成分时,往往主要关心的是成矿矿物组合,而对成矿前和成矿后的非金属矿物组合的空间分布规律则不予阐述。后者在矿带侧翼发育极广,并可作为发现隐伏矿体的标志。 根据矿物学资料实际应用的可能性,我们对金—硫化物—石英建造类型矿床和矿点中的非金属细脉状矿化填图时得到的材料进行了分析。这些矿床(点)产于里菲期变质岩层中的奥陶—下志留统的再生花岗岩类和辉长—闪长岩中。 标准矿床的矿带呈现为向北东陡倾的线性网状脉。金的工业富集与毒砂矿化和铋矿
In studying the ore composition of different types of gold deposits, the main concern is the mineral assemblage, while the spatial distribution of non-metallic mineral assemblages before and after mineralization is not explained. The latter has a very wide flank development and can serve as a hallmark for discovering hidden ore bodies. Based on the practical application of mineralogical data, we have analyzed the material obtained during mapping of nonmetallic vein-like mineralization in gold-sulphide-quartz type deposits and ore deposits. These deposits (spots) originate from the Ordovician-Lower Silurian regenerated granites and gabbro-diorites in the rifamy metamorphic strata. The mineralization of the standard deposit presents a linear reticulate vein steeply to the north-east. Gold industrial enrichment and arsenopyrite mineralization and bismuth ore
