Foreland basins adjacent to long-lived orogenic belts evolved in response to sporadic or continued crustal deformation. This evolution is recorded in the stratigraphic record and reflects the spatial and temporal variation in uplifts, the development of intrabasinal folds and faults, and basin subsidence. This study will examine the Late Paleozoic foreland in Nevada by focusing on a network of long sections along the axis of the basin and the included unconformities, structures and distinctive stratal packages that record how the foreland responded to the long-lived tectonism. Results should help delineate differences in style of orogenic processes along the foreland and through time and should provide the basis of developing a rigorous stratigraphic approach to the assessment of the tectonic histories for long-lived foreland basin systems.

与长期存在的造山带相邻的前陆盆地是在零星或持续的地壳变形作用下形成的。这一演化过程记录在地层记录中，反映了隆升的时空变化、基底内褶皱和断裂的发育以及盆地的沉降。本研究将考察内华达州的晚古生代前陆，重点关注沿盆地轴线的长剖面网络，以及包括不整合面、结构和独特的地层包体，这些记录了前陆如何对长期构造运动做出反应。研究结果将有助于描述沿前陆和各时期造山过程的风格差异，并为发展一种严格的地层学方法来评估长期前陆盆地系统的构造历史提供基础。
