Research in Structural Geology & Tectonics

Overview

The Structure & Tectonics Program at TTU is a diverse, vibrant, and collaborative association of faculty, researchers, & students who explore questions relating to the nature of magma migration and emplacement in the lithosphere, geomorphic signals of recent uplift in active mountain ranges, and the application of kinematic and dynamic analysis to geologic structures on Earth and in the solar system.

We provide a multi-disciplinary approach to structural analysis and utilize collaborations with petrologists, geochemists, and geomorphologists within the Department as well as colleagues at other institutions around the world.
