摘要
本文从构造分析入手,阐述乌拉山地区金矿脉的特征与集中分布的原因。认为金矿床的形成要求围岩应具备一定的变形变质程度,即适宜的构造活动强度,过强或太弱均不利于金矿床的形成。
Begining with structural analgsis, this paper formulates the characteristics of gold veins of wulashan and the reason of gold veins distributed concentratively in, specific sections. The author proposes that the forming of gold deposits requires favourable me-tamorphism: intensities of their host rocks, i.e. appropriate intensities of structural activity. Too strong or weak activities are unfavourable to the forming of gold deposit.
