9406029 Wells The Death Valley region is the most extended crustal section in the western Basin and Range Province. Numerous studies have led to two models with varying predictions for the slip rates along the strike-slip faults. This project will employ tectonic land forum techniques and new isotopic surface dating methods to elucidate the rate and style of deformation of the Black Mountains terrane in Death Valley, a parameter difficult to determine by other means. Results will help discriminate between the competing models and should also make a significant contribution to the application of isotope geochemical techniques to geomorphology problems

死亡谷地区是盆地和岭省西部最广阔的地壳剖面。大量的研究得出了两种模型，它们对沿走滑断层的滑动速率有不同的预测。本项目将采用构造陆地论坛技术和新的同位素表面测年方法，阐明死亡谷黑山地体的变形速率和变形样式，这是其他方法难以确定的参数。结果将有助于区分相互竞争的模型，并将对同位素地球化学技术应用于地貌问题作出重大贡献
