| 摘 要： | 辽西地区是世界重要的化石产地，中生界下白垩统九佛堂组是该地区重要的含化石层位，含有著名的热河生物群化石。通过对辽西地区九佛堂组诸多剖面的综合研究及化石组合对比，将辽西地区九佛堂组划分为3个岩性段，并整理完善了辽西九佛堂组珍稀化石层序列。根据对辽西九佛堂组珍稀化石层进行的对比研究，建立了肖台子层、报马营子层、西营子层等3个珍稀化石层，并分析了珍稀化石层岩性特征，认为珍稀化石层的形成与火山活动存在直接关系，首次提出辽西九佛堂期存在火山活动。

| 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, ie, 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. |
