近年来对早前寒式纪地质,特别是对这个时期特征的绿岩带与活动带的杂岩体的兴趣日益增长。一系列的有关会议及刊出的论文可作见证。在本国文献中普遍出现了“绿岩带”和“活动带”术语和概念。但在很多论文中这些术语的解释与国外文献中的根本不同,而在某些情况下又将“绿岩带”与“绿岩系”、“带”与“拗陷、“活动带”与“变质带”等分别等同起来。必须指出,“绿岩带”这个术语除了具有大地构造的意义外,还具有相当重要的成矿意义。考虑到
In recent years, there has been increasing interest in the Early Precambrian geology, especially for the greenstone and active complex of this period.
