摘要
Study on rock assemblage, petrochemistry and isotopic age of Ondorsum Group shows that this rock assemblage is characteristic of ORB and the REE pattern reflects a small inter-continent basin sedimentary environment. The assemblage is the product of Neo-proterozoic tectonic evolution at middle of north margin of North China Plate and provides a new basis for the study of crustal evolution of North China Plate.
