9805474JohnsonThe Denver Museum of Natural History (DMNH) proposes to develop an integrated paleobiological and geological framework for the Upper Cretaceous and lower Tertiary rocks in the Denver Basin using a multi-disciplinary approach of paleontology (plant megafossils and palynomorphs), magnetostratigraphy, and lithostratigraphy. The study will be based on a multitude of surface observations and fossil sites tied to a new cored well to be drilled by this project in cooperation with local, state, and government agencies. The well will be located in the center of the Denver Basin at the Elbert County Fairgrounds in Kiowa. Magnetostratigraphy, lithostratigraphy, and palynostratigraphy of the 610m well supported by this proposal will be used to erect a reference geochronology and biostratigraphy for the Denver Basin. This master section will be used to correlate basin-wide surface fossil sites and observations.The resulting data framework will be used to test three major hypotheses.- The first hypothesis is the Denver Basin contains two distinct unconformity-bounded sequences of synorogenic strata.- The second hypothesis is that the Cretaceous-Tertiary (K-T) boundary impact event at Chicxulub in Mexico caused greater biotic damage proximal to the impact site than distal to it.- The third hypothesis is that the evolution and infilling of the Laramide Denver Basin was driven by sediment supply and subsidence rather than by climate change.The intrinsic benefits of this research will be seen in the fields of sequence stratigraphy, basin tectonics, paleobotany, magnetostratigraphy, paleoclimatology, biostratigraphy, and extinction studies. The project will also have direct and immediate extrinsic benefits and will provide superb educational opportunities. The 620m sequence to be studied contains the majority of the aquifers that provide water for the rapidly growing populations in the central Denver Basin. The location of the reference will is such that it will provide much needed data on water quality and aquifer characteristics. The local, state, and government agencies that will cost share to help fund the drilling of the reference will benefit not only from the science funded by this proposal but will also undertake their own hydrological research on the well core. The USGS Division of Water Resources will coordinate this aspect of the research. The well itself has the potential to be developed as a water resource for the town of Kiowa and for Elbert County.As the umbrella organization for the project, DMNH will coordinate the basic research and educational endeavors resulting from this research. Educational opportunities of this project are immense since they will link popular science, such as dinosaur extinction and fossil rainforests, with local resource utilization issues in one of the fastest growing urban areas in the country. Educational products focusing on the topics of paleontology, geology, hydrology, and resource utilization could include such diverse products as teacher training workshops, adult education symposia, temporary exhibits, and outreach exhibits.

9805474Johnsonthe丹佛自然历史博物馆（DMNH）建议使用古生物学的多学科方法（工厂和palynomorphs），Magnetoprathy和lithatigrathy和Lithertrystraty和Lithertry，丹佛盆地的上白垩统和下三级岩石的综合古生物学和地质框架。 这项研究将基于与本项目与地方，州和政府机构合作钻探的新的核心核心地面观测和化石地点。 该井将位于基奥瓦（Kiowa）的埃尔伯特县集市（Elbert County Fairgrounds）的丹佛盆地中心。 该提案支持的610m良好支持的610m的磁层学，岩石地层学和palynostratatratigraphy将用于培养丹佛盆地的参考年代学和生物地层学。 本主节将用于将盆地范围范围的地表化石位点和观察相关联。所得的数据框架将用于测试三个主要的假设。-第一个假设是丹佛盆地包含两个不同的不整合阶层的序列。 to the impact site than distal to it.- The third hypothesis is that the evolution and infilling of the Laramide Denver Basin was driven by sediment supply and subsidence rather than by climate change.The intrinsic benefits of this research will be seen in the fields of sequence stratigraphy, basin tectonics, paleobotany, magnetostratigraphy, paleoclimatology, biostratigraphy, and extinction studies. 该项目还将具有直接和直接的外在利益，并将提供极好的教育机会。 要研究的620m序列包含大多数含水层，这些含水层为中央丹佛盆地中快速增长的种群提供水。 参考意愿的位置使得它将提供有关水质和含水层特征的急需数据。 将为参考钻探提供资金的本地，州和政府机构，不仅将从本提案资助的科学中受益，而且还将对井核心进行自己的水文研究。 USGS水资源部将协调研究的这一方面。 井本身有可能作为基奥瓦镇和埃尔伯特县的水资源开发。作为该项目的伞组织，DMNH将协调这项研究所带来的基础研究和教育努力。 该项目的教育机会是巨大的，因为它们将把恐龙灭绝和化石雨林等流行科学联系起来，并将其与该国增长最快的城市地区之一的本地资源利用问题联系起来。 关注古生物学，地质，水文学和资源利用的主题的教育产品可能包括诸如教师培训研讨会，成人教育研讨会，临时展览和外展展览等多样化产品。
