9405583 Aiken To fully characterize active tectonic systems such as the Pacific-North American transform boundary, it is important to examine the interactions at several spatial and temporal scales. This project sets out to quantitatively assess the spatial distribution of strain in the central Walker Lane Belt of the western Great Basin, presently undergoing active transcurrent and extensional faulting that results from the relative motion between the Pacific and North American plates, complicated by interaction between the Sierra Nevada and the Great Basin. The work will focus on three duration intervals from Mid Miocene to present-day deformation rates. Methods vary from mapping to GPS measurement of deforming Pleistocene lake terraces. Results are expected to provide a balanced view of the present strain regime of this area, in a historical context, and fully integrated with known geological data, that will be utilized in understanding how the basic plate interaction are modified and applied to continental margins.

9405583艾肯为了全面描述活动的构造系统，如太平洋-北美转换边界，重要的是考察几个空间和时间尺度上的相互作用。该项目旨在定量评估大盆地西部中央Walker Lane带的应变空间分布，目前正在经历活动的横流和伸展断裂，这是由于太平洋和北美板块之间的相对运动，以及内华达山脉和大盆地之间的相互作用而变得复杂的。这项工作将集中在从中新世中期到现代形变速率的三个持续时间段。从测绘到GPS测量变形的更新世湖泊阶地的方法各不相同。预计结果将在历史背景下对该地区目前的应变状况提供一个平衡的看法，并与已知的地质数据充分结合，这将被用来理解基本的板块相互作用是如何被修正和应用于大陆边缘的。
