COLLABORATIVE RESEARCH: Combined Cosmogenic Nuclides and Soil Stratigraphy for Alluvial Fan Chronology and Regional Correlation: Eastern Mojave, California

这是一个为期三年的合作研究项目，涉及内华达州里诺沙漠研究所的埃里克·麦克唐纳和史蒂夫·威尔斯；堪萨斯大学地质系的John Gosse，以及普渡大学PRIME实验室的分析工作。该项目的目标是：(1)制定一种冲积沉积物测年策略，考虑并尽量减少遗传和其他地质因素（如扰动）的影响，这些因素对10Be和26al等陆地暴露测年方法具有重要控制作用。(2)描述加州东部普罗维登斯山脉沿岸冲积扇的土壤和地层特征，收集地表和地下样本，以确定冲积扇的暴露年龄。并发展出区域年代地层学，并用它来解释加州东南部和内华达州西南部的气候和构造记录。

GosseThis is a three-year collaborative research project involving Eric McDonald and Steve Wells at the Desert Research Institute in Reno, Nevada; John Gosse at the University of Kansas Department of Geology, and analytical work at PRIME Lab, Purdue University.The objectives of this project are to (1) develop a strategy to date alluvial sediments that considers and minimizes the effects of inheritance and other geological factors such as turbation, which are significant controls on the terrestrial exposure dating methods such as 10Be and 26 Al. (2) Characterize the soils and stratigraphy in the fans along the Providence Mountains, eastern California, collect surface and subsurface samples to establish the exposure age of the alluvial fans, and develop a regional chronostratigraphy, and use this to interpret climatic and tectonic records for southeastern California and southwestern Nevada.
