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

小行星9405486 为了充分描述活跃的构造系统，如太平洋-北美转换边界，重要的是要检查在几个空间和时间尺度上的相互作用。 该项目旨在定量评估西部大盆地中部步行者巷带的应变空间分布，该带目前正经历着太平洋和北美板块之间的相对运动所导致的活跃的横流和伸展断层，而内华达州山脉和大盆地之间的相互作用使其复杂化。 这项工作将集中在三个持续时间间隔从中新世中期到现在的变形率。 更新世湖阶变形的方法从制图到GPS测量各不相同。 预计研究结果将从历史背景出发，全面综合已知地质数据，对该地区目前的应变状况提供平衡的看法，这些数据将用于了解基本板块的相互作用是如何改变并适用于大陆边的。

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.
