摘要
以胶南构造混杂岩带中榴辉岩的围岩——套程度不同的糜棱岩化岩石为研究对象,重点研究了其显微形变的结构特征及环境意义、石英组构特征及动力学信息,并讨论其形成的古构造环境和构造机制。
The ecologite with deep sources,widely emerged in the Jiaonan tectonic complex belt,has the main country rocks of garnet peridotite and halleflintgeiss that have various degrees of mylonization.This paper studies the texture (fabric) and the structure of the micro-deformation of these rocks,and discusses their paleo-tectonic setting and tectonic mechanism.It is shown that the miloniric country rocks of the ecogite were the results of the tectonic movement between the North China Plate and the Sorth China Plate.
