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.

要了解大陆伸展的动力学，需要从三维的角度来了解伸展的时间、幅度和速度，然而许多研究假设了平面应变，只考虑了二维的伸展过程。该项目将通过对北科罗拉多河伸展走廊中新世生长断陷盆地的研究，研究跨走向和沿走向伸展程度的变化，伸展和岩浆作用之间的关系，以及与调节带相邻的特征。这些数据有望用于开发大陆伸展的三维模型。
