COLLABORATIVE RESEARCH: Geodynamics of the Central Walker Lane, Western Great Basin

9405486 Oldow为了充分表征太平洋-北美转换边界等活动构造系统，重要的是研究几个时空尺度上的相互作用。本项目旨在定量评估西部大盆地中部沃克莱恩带的应变空间分布，该带目前正处于活跃的跨流和伸展断裂，这是由太平洋板块和北美板块之间的相对运动造成的，内华达山脉和大盆地之间的相互作用使其复杂化。这项工作将集中在从中新世中期到现在的变形速率的三个持续时间间隔上。变形更新世湖泊梯田的方法从制图到GPS测量都有。预期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，这将用于理解基本板块相互作用是如何被修改并应用于大陆边缘的。

9405486 Oldow 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.
