| Abstract: | During Cenozoic time, the Colorado Plateau was raised about 2km above sea level. The most-recent and best-documented uplift of the plateau (~1km) has been concentrated at its southwest margin between 6 and 1 Ma, whereas the eastern Colorado Plateau may have been at high elevations since Eocene time. To better understand the recent tectonic activity at the southwest margin of the Colorado Plateau, we compile detailed crustal thickness and density information from seismic and gravity data for a region that includes northwest Arizona and the southern tip of Nevada. This information is used to isolate the mantle contribution to uplift. We speculate that uplift may result from subduction-related thinning of the continental lithosphere. -from Authors |
