Requires the equivalent of the Bachelors degree with a major in geosciences or allied discipline.
The Department of Geosciences, University of Arizona, focuses on research and education in the nature, genesis, and history of the Earth and its crust, and the evolution of the environment and biota at the Earth's surface.
Our faculty, graduate, and undergraduate students are active in biogeochemistry; climate dynamics; geoarchaeology; geochemistry; geochronology; geomorphology; geophysics; mineral resources; mineralogy; paleolimnology; palynology; paleontology; petrology; sedimentology and stratigraphy; structure; and tectonics.
We encourage interdisciplinary approaches to research in the geosciences, both within the department and through interdepartmental programs.
US National Research Council Rankings - We are one of nine programs, and one of only four in public institutions, to rank in the top 10 in both "survey" and "regression" rankings.
The Department of Geosciences at the University Of Arizona is ranked #3 In Geology, #8 In Earth Sciences, And #11 In Geochemistry Iin the most recent U.S. News and World Report National Survey of Graduate Programs.
