第聂伯河中游前寒武纪含金闪石交代岩可分两类:一类以碳酸盐成分为主,另一类以石英为主。在岩石中,金粒大部分为不规则状,与硫化物密切共生,分布在岩石解理和裂隙以及碳酸盐和石英粒间,形成较晚。热夜作用使含金交代岩中的金活化转移而成矿。金矿化可与遣山建造弱发育的原始地槽侵入-火山带的Au-Cu-Mo矿化相对比。 Precambrian gold-bearing amphibole-bearing rocks can be divided into two types in the middle Dnieper: one is mainly carbonate and the other is quartz. In the rock, most of the gold grains are irregular and closely intergrowth with sulphide. They are distributed between rock cleavage and fissures and between carbonate and quartz grains, forming later. The hot night effect gold-bearing rocks in the activation of the transfer of gold and mineralization. Gold mineralization can be compared with the Au-Cu-Mo mineralization of the volcanic belt in the weakly developed, weakly developed intrusive trough in the Seishan.
