Abstract

Abstract: Lake sediments of Yixian formation in the western part of Liaoning Province output the famouse “Jehol Biota” fossils， it is a hot issue for the study of the palaeoenvironment at this period. This paper focuses on the varves in Dakangpu Layer and reconstruct the lacustrine palaeoenvironment. New understanding of the palaeoclimate in this period is obtained through carefully observing the composition， type， thickness of varve in the field and laboratory. The change of varve thickness indicates the decrease in the precipitation and deposition rates in Dakangpu stage. The thickness of the varve between the flood deposits can be used to interpret the frequency and scale of the flood events. Combined with the deposition and preserved environmental conditions of modern varves， during the deposition period of Dakangpu Layer， there is a specific depositional environment and a deep， stratified， oxygen-restricted， low surface area/depth ratio lake.

Key words: Yixian formation, Jehol Biota, varves, stratified lake, oxygen-restricted environment
