摘要
内蒙古中部地区早古生代白乃庙群地层主要由绿泥片岩段(Ob^1、Ob^3)和长英片岩段(Ob^2)组成,花岗闪长斑岩(386Ma)侵入于地层之中。白乃庙群和花岗闪长斑岩一同遭受了推覆型韧性剪切作用。
The early Palaeozoic Bainaimiao group is well developed in the middle part of the inner Mongolia. It consists mainly of the chlorite-schist member (Ob^1, Ob^3) and the felsic-schist member (Ob^2) , and had been intruded by granodiorite-porphyry (386Ma). Both of the Bainaimiao group and the granodiorite-porphyry had suffered from ductile shearing of the nappy type.
