Research Statement

It is increasing clear that the mantle underlying continents is much more varied than the surface topography, crustal province boundaries, or active tectonics would suggest. Most of the mantle structure underlying tectonic mountain ranges is three-dimensional in form even though the mountain ranges are dominantly two dimensional chains. Often, post-orogenic uplift of these mountain ranges, in excess of that predicted by simple crustal thickening models, is required by geologic data (thermocron, river incision, sediments). This requires post-orogenic mechanisms that can create dynamic surface adjustments such as: the removal or retrograde metamorphism of eclogite; convective removal or delamination of over thickened thermal lithosphere; or diapiric invasion of the lithosphere by an upwelling asthenosphere (e.g., diapirs from a 410 km discontinuity partially molten layer). Constraining the relative effects of these different geodynamic processes is crucial to understanding continental orogens and continental evolution in general.
