Metamorphosed Lithostratigraphic Sequences of Precambrian in Yinshan Region

WANG Ji\ SUN Yufang (Inner Mongolia Institute of Geology)  
The metamorphosed lithostratigraphic sequences of Precambrian in Yinshan region have not yet been researched systematically.From 1990 in research of the geochrologic framework of metamorphic group,the author have renewly divided the Precambrian lithostratigraphic units by using “structure stratum events”and metamorphic structural analysis,and the geological ages of metamorphosed groups are measured with methods of grain zircon U Pb geological age and Sm Nd isochron dating.The geological age structural framework of Precambrian metamorphic group in Yinshan region and its detailed division for the sequences are established and given as follows. The oldest lithostratigraphic unit,Xinghe Group complex of the Middle Archaeozoic Erae is mainly consisted of ultramafic mafic volcanic rocks and pyroclastic rocks ,both of them had undergone granulite facies metamorphism.All of these rocks were appeared as xenoliths and residual of the supracrustal rocks in the ocean consisting of TTG rocks.The lower lithostratigraphic unit of Late Achaeozoic has been named Jining group complex or Wulashan Group complex,which had also been metamorphosed to high amphibolite facies and granulite facies.In its upper part,Se’ertengshan Group is a set of granite greenschist rocks,The sedimentation of palaeo Proterozic Erdowa Group started from 2 3 Ga,and its upper part is Bayun’ebo Group or Zha’rtai Group which is typical rift sediments.The boundary between Early and Middle Proterozoic may be 1 6 Ga or so ,e g ,the top interface of Bayun Obo Group or Zhartai Group.The later cover sediments over Bayun’ebo Group or Zhartai Group are absent in Yinshan region.The Cambrian system shows paralled unconformity on Shinagan Group The details are seen in Table 1.
