ABSTRACTSGER Sequence stratigraphy and paleocommunity analysis of an Oligocene reef tract, Lares Limestone, Puerto Rico (EAR-0224868)Claudia JohnsonIndiana UniversityThe Lares Limestone in Puerto Rico provides a unique opportunity to study a 30 million year old Oligocene reef from its initiation surface through its drowning, and from its seaword to landward expression. The opportunity is short lived, for heavy tropical rainfall has compromised the quality of this roadcut exposure. There is an urgency to document and analyze this tropical carbonate platform and to address hypotheses in the fields of paleobiology, sequence stratigraphy and paleoclimatology. Research results will provide valuable information on evolution in a tropical environment.

波多黎各Lares石灰岩渐新世礁域的层序地层学和古群落分析印第安纳大学Claudia Johnson波多黎各的Lares石灰岩为研究一个3000万年前的渐新世礁提供了一个独特的机会，从它的初始表面到它的淹没，从它的海字到向陆地的表达。 这个机会是短暂的，因为大量的热带降雨已经损害了这个道路切割暴露的质量。 有一个迫切需要记录和分析这个热带碳酸盐台地，并解决在古生物学，层序地层学和古气候学领域的假设。 研究结果将为热带环境中的进化提供宝贵的信息。
