作者研究了库兹涅茨克山、外贝加尔、东萨彦岭等地的花岗岩类碱性交代岩中的金矿化,揭示出碱性交代岩中新的金矿化类型的特征。这类金矿化产于地壳的造山构造和活化构造中,赋存于花岗岩类石英-钠长石化带,与流体钠-氯或钠-氯-氟专属性的花岗岩类侵入杂岩体的形成有关。可将矿化看作是同一碱质交代作用的最后阶段。矿化以细脉浸染型的金和稀有金属矿化为主。较富的金矿化分布于交代作用带钠长石和硅化的最强地段。在成矿研究中应着重注意这类交代岩。
The authors studied the gold mineralization in granitic alkaline metamorphic rocks in the Kuznetskoye, Outer Baikal and East Sayan Mountains, revealing the characteristics of the new gold mineralization in alkaline metamorphic rocks. This type of gold mineralization occurs in the crustal orogeny and activation structure and occurs in the granitoid quartz-albite zone and forms with the granitic intrusive complexes of fluid sodium-chloride or sodium-chlorine-fluorine related. Mineralization can be seen as the last stage of metathesis. Mineralization to fine vein disseminated gold and rare metal mineral-based. The richer gold mineralization is distributed in the strongest section with albite and silicification metasomatism. In the study of mineralization, we should pay attention to this type of metasomatism.
