The Kuanchuanpu Formation, occasionally reclassified as the Kuanchuanpu Member of the Dengying Formation, is a geologic formation located in Shaanxi province in China. It is one of the earliest Cambrian formations, dating right to the Ediacaran-Cambrian boundary. This formation preserves numerous meiofauna through Orsten-type preservation.
