AbstractPrevious research in the Bighorn Basin has provided tantalizing evidence suggesting a relationship between biotic change and shifts in climate at the time of the Paleocene/Eocene boundary and two early Eocene time periods, but poor resolution of critical parts of the record renders the correlation inconclusive. Using a combination of approaches -magnetostratigraphy, physical stratigraphy, paleosols, and mammalian faunas- this project will developed a high- resolution chonostratigraphy and provide the framework for correlating upper Paleocene- lower Eocene sections across the basin, and for establishing whether regional event can be correlated with the marine record. The Bighorn Basin is possibly the best localities globally where sediments recording coeval changes in climate, mammalian faunas, and floras at the Paleocene/Eocene boundary and two early Eocene intervals have been preserved. The proposed work is essential for future research seeking to establish the relationship between biotic and climate changes globally during the early Tertiary interval of Greenhouse conditions.

摘要：先前对比格霍恩盆地的研究提供了诱人的证据，表明古新世/始新世边界和始新世早期两个时期的生物变化与气候变化之间存在关系，但记录的关键部分分辨率较差，导致相关性不确定。该项目将综合运用磁性地层学、物理地层学、古土壤和哺乳动物动物群等方法，开发高分辨率地层学，并提供框架，用于关联整个盆地的上古新世-下始新世剖面，并确定区域事件是否可以被预测。与海洋记录相关。大角盆地可能是全球最好的沉积物记录古新世/始新世边界和两个早始新世区间的气候、哺乳动物动物群和植物群的同期变化的地区。拟议的工作对于未来寻求在温室条件的第三纪早期期间建立全球生物与气候变化之间的关系的研究至关重要。
