| Abstract: | 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. |
