Abstract:

The western Liaoning region is a world-class fossil site, in which the Jiufotang Formation is an important fossil-bearing stratum, hosting the famous Jeholbiota fossils. Through comprehensive research on the many sections and fossil assemblage comparison, the Jiufotang Formation can be divided into three units, i.e., the Xiaotaizi, Baomayingzi and Xiyingzi are fossil-bearing sequences. The lithological characteristics of fossil-bearing beds are directly related to volcanic activities, and the fossil-bearing beds are always located in the top of lithologic cycle. We first propose that there were volcanic eruptions during the deposition of the Jiufotang Formation.

Key words: western Liaoning, Jiufotang Formation, fossil-bearing bed, stratigraphic division
