Continental basins resulting from extension are complex, being influenced by the style of normal faulting, reactivation of older features and local climatic conditions. This project will examine in some detail the depositional and structural evolution of the Great Salt Late Basin at the eastern edge of the Basin and Range Province. The work will integrate seismic, stratigraphic and paleoecologic data with three-dimensional basin depositional modeling in order to produce a detailed interpretation of how this basin developed through the Neogene. Results will add to the understanding of the interaction of tectonics, climate and deposition in a continental extensional environment.

伸展作用形成的陆相盆地是复杂的，受正断层样式、老地貌的重新激活和当地气候条件的影响。该项目将较详细地研究位于盆地和山脉省东部边缘的大盐湖晚期盆地的沉积和构造演化。这项工作将把地震、地层和古生态数据与三维盆地沉积模拟结合起来，以详细解释该盆地是如何在新近纪发育的。这些结果将有助于理解大陆伸展环境中构造、气候和沉积的相互作用。
