n.动力变质作用
Abstract In this article a basic concept on dynamometamorphism as a result of the action of tectonic forces is presented. 摘 要 本文提出了构造动力变质作用的基本概念。
Xiaertai rock group,a set of metamorphic rock system in Xiaertai area,has experienced strong ductilebrittle deformation and then thermal contact metamorphism and dynamometamorphism in the late stage. 经原岩恢复可将下二台岩群分为三个岩组:盘岭岩组,黄顶子岩组及烧锅屯岩组,其原岩建造分别为火山岩建造、碳酸盐岩建造及碎屑岩建造。
