Cenozoic Basin and Range Structure Near Yerington, Nevada

目前的一个假说是，在美国西部的盆岭省，上地壳因脆性的正断层作用而变薄，而下地壳则经历了韧性伸展。地震研究表明，在内华达州西部，整个地壳被减薄到20-30公里，然而，关于上地壳的同等数据并不完整。该项目将通过记录通过耶灵顿地区到沃克巷的上地壳延伸，扩展先前关于耶灵顿地区脆性延伸的研究。结果将与现代伸展的地球物理和新构造研究相结合，预计将产生改进的大陆地壳伸展演化模型。

A current hypothesis is that in the Basin and Range Province in the Western United States the upper crust has been thinned by brittle normal faulting, whereas the lower crust has undergone ductile stretching. Seismic studies have indicated that the entire crust is thinned to 20-30km in western Nevada, however equivalent data on the upper crust are incomplete. This project will expand on prior studies of brittle extension in the Yerington area by documenting upper crustal extension through the Yerington area to the Walker Lane. Results will be integrated with geophysical and neotectonic studies of modern extension and are expected to yield improved models for the evolution of continental crustal extension.
