Sedimentary basins are among the most conspicuous results of Neogene continental extension in the North American Cordillera, however, the connection between structural development and sedimentologic response is less than clear. This project will take advantage of an uplifted and dissected late Miocene-Pliocene extensional basin exposed in the Panamint Valley and Death Valley area of southeastern California. The work will involve mapping, chemical analysis, sedimentology and age dating techniques to establish the structural history and associated sedimentologic response. Results will provide an added dimension to the subject of extensional tectonics.

沉积盆地是北美科迪勒纪晚第三纪大陆伸展作用最显著的结果之一，但构造发育与沉积学响应之间的关系尚不清楚。该项目将利用一个隆起并解剖的晚中新世-上新世伸展盆地，该盆地暴露在加利福尼亚州东南部的Panamint山谷和死亡谷地区。这项工作将涉及测绘、化学分析、沉积学和年龄测定技术，以确定构造历史和相关的沉积学响应。这些结果将为伸展构造学的主题提供一个额外的维度。
