Geoscience is an all-encompassing term used to refer to the earth sciences. The Department of Geosciences offers programs at the undergraduate and graduate levels where students can learn about topics such as earth processes; the origin and evolution of our planet; the chemical and physical properties of minerals, rocks, and fluids; the structure of our mobile crust; the history of life; and the human adaptation to earthquakes, volcanoes, landslides, and floods.

The owner of a uranium mine near the Grand Canyon wants state regulators to allow a higher level of arsenic in groundwater under the facility. Two scientists, however, object to the proposal, arguing regulators shouldn’t approve it until a more robust investigation into the elevated arsenic levels takes place. Energy Fuels Resources, the owner of the Pinyon Plain Mine, says its investigation was thorough and that operators aren’t at fault.
