文摘
Carbon and oxygen isotope analysis of Xixiangchi Group shows that the bottom boundary of the Upper Cambrian is defined for the first time. The Xixiangchi Group formed in a high salinity on shore marine sedimentary environment with a warm to dry climate and underwent a slow regression after a rapid transgression in the early and middle stages, In the late stage it entered a rapid regression after a slow transgression.
