本文通过追述脉金矿床的成因和历史发展,指出从元古代到新生代变质带中的脉金矿床与太古代变质岩中的脉型矿床具有很多相同特点,通过对不同时代脉金矿省的详细研究,指出不论是太古代还是年轻的成矿省的成矿作用是相同的。地质、地球化学,地球物理资料的分析表明,从太古代到新生代,构造控制的脉金矿床,在构造、矿化、金属矿物和地球化学特征方面也具有广泛的相似性。从而认为产在变质地体中的脉金矿脉系统是一组单独的或有继承性的后生贵金属矿床。提出了该类矿床是形成在整个深部地壳范围内,从韧性剪切带到脆-韧性到脆性的构造类型,从麻粒岩相延伸到次绿片岩环境的地壳连续模式。这个模式很好地解释了脉金矿床的很多地质特点,对其现代分布特点也能作出合理的解释。
This paper points out that the vein-gold deposits in the Metamorphic Belt from the Proterozoic to the Cenozoic and the vein-type deposits in the Archean metamorphic rocks have many similarities through the genesis and historical development of the Pui Fa vein gold deposit. A detailed study shows that the mineralization in the mineralized provinces, whether ancient or young, is the same. Geological, geochemical and geophysical data indicate that tectonically controlled vein-gold deposits from the Archean to the Cenozoic also have broad similarities in tectonism, mineralization, metallogenetic and geochemical characteristics. Therefore, it is concluded that the vein-gold vein system produced in the metamorphic terrain is a group of single or inherited epigenetic precious metal deposits. It is proposed that this type of deposit is a continuous crustal continuation mode formed from the granulite facies to the secondary greenschist environment within the entire deep crust, from the ductile shear zone to the brittle-ductile to brittle structural type. This model explains a lot of geological features of the vein-gold deposit and can give a reasonable explanation of its modern distribution.
