A major phenomena of Cenozoic tectonics in the southwestern United States involves detachment faults and associated Continental extension. Recently, a major early Miocene extensional belt has been recognized and described in the Mojave Desert. This project will continue systematic analysis of this extensional terrane by a combination of detailed field mapping, structural analysis, stratigraphic and petrologic analysis, P-T path analysis, paleomagnetic studies, geochronologic -- thermo- chronologic studies and thermal modeling. This work will be integrated and focussed on the extension in the Mojave Rift and its effects on the paleogeographic evolution of the region.

美国西南部新生代构造的一个主要现象涉及滑脱断层和相关的大陆伸展。 最近，在莫哈韦沙漠中发现并描述了一个主要的早中新世伸展带。 该项目将通过详细的野外测绘、结构分析、地层学和岩石学分析、P-T 路径分析、古地磁研究、地质年代学-热年代学研究和热模拟相结合，继续对这一伸展地体进行系统分析。 这项工作将整合并重点关注莫哈韦裂谷的延伸及其对该地区古地理演化的影响。
