Different viewpoints have been proposed about the sedimentary environment of Jurassic Buqu Formation in northern Qiangtang Basin. Based on the geological settings, paleogeomorphological features and the sedimentary characteristics of Buqu Formation in Qiangtang Basin, it is confirmed that Buqu Formation belongs to carbonate ramp sedimentation. Based on outcrop observation and description, combined with lithofacies analysis, the ramp is divided into three kinds of subfacies, including inner ramp, mid-ramp and outer-ramp, and seven kinds of microfacies, such as tidal flat, lagoon and shallowshoal etc. The sedimentary facies sequences and evolution of this period are established.
