Cashman0001130The Sierra Nevada - Basin and Range boundary zone in northwestern Nevada - northeastern California records the superimposed effects of several tectonic regimes. In this area, Neogene basins straddle both the geologic/physiographic boundary between the Sierra Nevada and the Basin and Range, and the time span during which it evolved, thus providing the opportunity to better understand paleotopography and tectonics along this orogenic boundary. Results will help answer several long-standing questions of regional interest, and will also pertain to fundamental questions about how and why continental crust deforms.

Cashman 0001130位于内华达州西北部-加州东北部的Sierra内华达州- Basin and Range边界带记录了几种构造体制的叠加效应。 在这一地区，新近纪盆地跨越内华达州山脉和盆地与山脉之间的地质/自然地理边界，以及它演变的时间跨度，从而提供了更好地了解沿着这一造山边界的古地形和构造的机会。 研究结果将有助于回答几个长期存在的区域问题，也将涉及有关大陆地壳如何以及为什么变形的基本问题。
