摘要
本文论述了构造动力作用与元素地球化学特征之间的内在联系。重点分析了金、银等元素富集、成矿的构造地球化学环境,提出了构造动力作用与金、银矿的形成具密切成生联系以及金、银矿化对构造形迹力学性质具有较明显选择性的新认识。认为金的富集成矿主要与偏碱性、较还原的压(扭)性构造有关,而银则趋向于与偏张性的构造环境关系密切。
The authors discuss in the paper the internal relations between the dynamic structures and the geochemical characteristics of ore-forming elements and analyze the tectono-geochemical environment of enrichment and mineralization of the elements such as gold and silver. The new view is given hereby that there is a close genetic relationship between the dynamic structures and the formation of gold and silver ores and that the gold-silver mineralization has an obvious selectivity to the mechanic property of structural traces. If is concluded that the gold enrichment and mineralization have a relation with the compressive or compresso-shear structrues which exist in the environment of meta-alkaline and more reduction, and that the silver enrichment and mineralization are in close relationship with relative tension structures.
