Understanding the dynamics of continental extension requires a three-dimensional perspective of the timing, magnitude, and rate of extension over broad regions, however many studies have assumed plane strain and considered processes of extension in only two dimensions. This project will examine across-strike and along- strike variations in the amount of extension, relations between extension and magmatism and features adjacent to accommodation zones by study of Miocene growth-fault basins in the northern Colorado River extensional corridor. These data are expected to be useful in development of three-dimensional models for continental extension.

了解大陆扩展的动力学需要对广泛区域的时间，幅度和延伸速率的三维视角，但是许多研究都假定了平面应变并仅在两个维度中考虑了扩展过程。 该项目将通过研究北科罗拉多河扩展走廊的中新世生长型盆地的研究，研究延伸量，延伸与岩浆之间的关系，扩展与岩浆之间的关系以及与住宿区相邻的特征的跨撞差异。 预计这些数据将在开发大陆扩展的三维模型中很有用。
