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.

Geoscience In The News

USA Today

Less than 1% of NASA’s workforce are astronauts. The majority of professionals have carved out unique — if less public — roles supporting our nation’s space goals. Here are some of NASA's most interesting earthbound personnel.

New York Times

Minerals in the space rock provide hints about the early history of the red planet, when water was flowing on the surface.

Scientific American

Blasted off Mars by a giant impact long ago, the meteorite Teghaza 001 eventually fell to Earth in the Sahara Desert. Now it’s revealing previously hidden chapters of Mars’s deep past

The nonprofit Grand Canyon Trust says its new analysis of monitoring wells in the Grand Canyon region shows wells within a nearby uranium mine have unusually high arsenic levels compared to other groundwater sources in the area.

Inside Climate News

Pinyon Plain Mine representatives argue that the toxic metal is naturally occurring, not contamination from the mining operation.

Scienceline

Arizona recently raised an arsenic limit at one monitoring well at Pinyon Plain Mine, where scientists are still trying to understand how water moves underground.

Thomas Lamont (Geology) had a paper titled, "Porphyry copper formation driven by water fluxed crustal anatexis during flat-slab subduction," published on Nov. 4 in Nature Geoscience. It has long been recognized that many of the worlds largest porphyry copper deposits (copper ore formed by magmatic-hydrothermal fluids associated with granitic…
Krishnakumar Nangeelil, Peter Dimpfl, Zaijing Sun (all Health Physics and Diagnostic Sciences), Shichun Huang (currently faculty at UTK, a former member of the department of geosciences at UNLV), and Mayir Mamtimin (Halliburton) published an article titled, "Preliminary Study on Forgery Identification of Hetian Jade with Instrumental Neutron…
Simon Jowitt and Brian McNulty (Geoscience) recently published a paper in Renewable and Sustainable Energy Reviews on critical metals – often discarded as a byproduct of mining operations – that are vital components in the global push for low-carbon energy generation, storage, and transport. Researchers explored the current global…
Amanda Ostwald and Arya Udry (both Geoscience) and their collaborators, Valerie Payré (NAU), Esteban Gazel (Cornell), and Peiyu Wu (Cornell) published a paper, “The Role of Assimilation and Factional Crystallization in the Evolution of the Mars Crust”, in the journal Earth and Planetary Science Letters. Ostwald is geoscience graduate student, and…
Shichun Huang (Geoscience), Min Li (Physics and Astronomy) and their colleagues published an article, Sulfur Isotopic Signature of Earth Established by Planetesimal Volatile Evaporation, in Naure Geoscience. Using sophisticated ab initio and thermodynamics calculations, they showed that the Earth's sulfur, an important volatile element, budget is…
