The figure above symbolizes the teaching and research scope of the Earth & Environmental Sciences Department and its faculty. Like the Earth and its spheres, the department consists of groups of faculty who interact and collaborate within and between groups representing the 5 aspects of the global Earth system. Those concerned with the Geosphere are geoscientists who study the solid Earth and consist of geophysicists, geochemists, structural geologists/tectonophysicists, sedimentologists and geomorphologists; Those concerned with the Biosphere are ecologists, zoologists, botanists and paleontologists whose interests range from microbes to large flora and fauna and from extant to extinct species; Atmospheric scientists are concerned with climate, and atmospheric dynamics and chemistry; The Hydrospheric faculty study both ground and surface water including lakes, rivers and oceans and their physics and chemistry; Faculty interested in the Anthroposphere study the interaction of the human population with all aspects of the Earth system.
Biostratigraphy Research

Biostratigraphic data sets are compiled with the use of foraminifers, conodonts, and radiolarians present in strata of the Bell Canyon Formation (late Middle Permian) and its stratigraphic equivalents in the Guadalupe and Apache mountains. Integration of a conodont biostratigraphy of the Lower Permian of Kansas are done in collaboration with other universities (Oklahoma State) and the USGS.

Climate Research Group

Comprehensive climate models in collaboration with the National Center for Atmospheric Research are applied to predict climate and marine carbon cycle for the past, present and future. Current UTA research projects focuses on paleoclimatic changes during hothouse climates, e.g. the Paleocene Eocene Thermal Maximum (55 million years before present), the Permian-Triassic boundary (250 million years before present), and climate and carbon cycle changes during the last deglaciation.

Environmental Geochemistry Research

Current work is focused on methods of converting the environmentally hazardous element lead (Pb), often found in soils in high concentrations, to a less hazardous form. Easily bio-accessible lead in urban soils poses a toxicological threat to pediatric populations, converting the Pb in situ to a sparingly soluble form reduces that threat. Current efforts by the group are focused the cost-effective addition of phosphates to soil to facilitate the formation of highly insoluble Pb-phosphate phases.

Geochemistry Research

Field- and laboratory-based research program that concentrates on reconstructing paleoenvironmental changes and identifying the underlying climate forcing mechanisms responsible for the changes. Currently funded projects include 1) development of Holocene/Pleistocene records of climate change preserved in stalagmites from the south-central Appalachians of West Virginia and Tennessee, and 2) development of Permo-Triassic paleoceanographic records that help resolve the underlying cause(s) of one o

Geomechanics Research

Geomechanics research in EES is grounded in field work, laboratory rock and fracture mechanics, and theoretical mechanical modeling, all of which are applied to problems related to earthquake hazards, the architecture of petroleum fields, and the design of underground mines. Current research is focused on experimental investigation of rock friction at fast slip rates and large normal stress, field-based study of the mechanics of kilometer-scale clastic intrusions, and numerical investigation of roof stability problems in mines related to topographic stress perturbations.

Hydrogeology Research

Focus on the studies of chemical processes in the intersection of the hydrosphere, geosphere, and biosphere, particularly on the nexus of environment, energy, and water resources. In particular, the coupling of physical, chemical, and biological processes, and the application of hydrology and aqueous geochemistry to critical issues of groundwater contamination and energy security such as nuclear waste disposal and carbon sequestration.

Neotectonics-Geodesy Research

Neotectonics ,a subdiscipline of tectonics, studies the motions and deformations of the Earth's crust at recent geological time. Research initiatives at UTA focuses on the plate movement and boundaries of the North American and Caribbean plates using seismic and marine geophysical survey data, together with the global positioning system (GPS).
Paleoceanography Research

Research in paleoceanography uses geochemical tracers in the modern environment and on ancient samples to test our understanding of biogeochemical cycling in the ocean with the ultimate goal of better constraining these processes and understanding records of the past. Current research employs non-traditional stable isotopes (Ca, Sr) in combination with more traditional paleoclimate proxies.

Sedimentology Research

Sedimentary rocks provide the most continuous record of mountain building process, climate change, and paleogeography. Current research focuses on describing sedimentary structures and stacking patterns, collecting quantitative proxy data, interpreting the processes involved in sediment transport, determining topographic, climatic and diagenetic influence on sediment isotopic record, and subsidence modeling of forming accommodation space. These works constrain the mechanisms creating sedimentary basins, and the climatic and environmental changes associated with the accommodation.

Structural Geology and Tectonics Research

Research highlights the measurement of natural strain and its relationship to folds and faults. Geometric and numerical modeling of geologic deformation is utilized. Research has been conducted on fracturing and fracture density studies as well as regional structural geology particularly in the areas of the Ouachitas, Arbuckles, Appalachians, U.S. Rocky Mountains, California Coast Ranges and theTaiwan Foldbelt.
