Phil Resor, associate professor of earth and environmental sciences, and Gus Seixas ’10 are co-authors of “Constraints on the evolution of vertical deformation and Colorado River incision near eastern Lake Mead, Arizona, provided by quantitative structural mapping of the Hualapai Limestone,” published in the February 2015 issue of Geosphere, Vol. 11, pages 31-49. The paper includes research from Seixas’s honors thesis at Wesleyan.
In this study, the authors quantify the structural geometry of Hualapai Limestone, which was deposited in a series of basins that lie in the path of the Colorado River. The limestone was deformed by by a fault pair known as the Wheeler and Lost Basin Range faults.
