摘要
The Lower Cretaceous Yixian Formation is the basal formation of the Jehol biota where the abundant and exceptionally well-preserved fossils were discovered. The recent systematic field study of the depositional environment indicates that there were several lacustrine carbonate intervals in the four sedimentary beds of the Yixian Formation. The authors systematically studied the distribution and the lithotypes of lacustrine carbonates both in the field and with laboratory analysis. Finally, the authors propose a lacustrine carbonate sedimentary facies model for the Yixian Formation.
