Abstract: The Cambrian in Shanyang, Shanxi Province, is well exposed, with a distinct facies indication and abundant body fossils and trace fossils, so the area is one of the key areas for the study of the Cambrian in the Qinling Mountains. In the past two yearsothe Chinese geologists have found the zonal fossil Redliehia chinensis at the top of the Lower Cambrian and the index fossils Kunmingaspis sp. and Chittidilla sp. and the trace fossils Chondites and Planolites at the base of the Middle Cambrian. thus providing important grounds for the regional stratigraphic division, analysis of lithofacies-paleogeography and correlation between the province and other parts of China.
