Undergraduate Studies [back to top]

The undergraduate program in the Department of Geological Sciences is designed to provide an understanding of the materials that constitute the earth and the processes that have shaped the earth from deep in its interior to the surface environment. Geology is a science that applies all the basic sciences—biology, chemistry, mathematics, and physics—to understanding earth processes in the historical context of geologic time. It is a science that explores problems by combining field investigations with laboratory experiments and theoretical studies.

Geology addresses many natural hazards—earthquakes, flooding, and volcanic eruptions—that affect humans. It also addresses the impact of humans in degrading the earth’s surface environment, where we pollute rivers and ground water, cause rapid erosion and landslides, or attempt to re-engineer rivers and shorelines.

Preparation. High school students planning to major in geological sciences should include in their high school program algebra, geometry, trigonometry, geography, and science (physics, chemistry, biology, or earth science).

Students who transfer to the department after two years of college work elsewhere should have completed a year of general chemistry, a year of general physics, and a year of calculus. If available to the student, a year of general geology with laboratory is recommended. In addition, transfer students should have completed as many as possible of the university requirements for undergraduate degrees.

Careers. Career opportunities for geologists are best for students holding advanced degrees. Professional positions that are open to students with master of science degrees include work in applied geology with petroleum and mining companies, environmental consulting firms, and state and federal agencies. Geologists and geophysicists with doctor of philosophy degrees have opportunities in university and college teaching as well as research positions in federal agencies and private industry. Students are therefore advised to earn a graduate degree for most professional positions. Graduates with bachelor’s degrees can qualify for positions as laboratory technicians or field assistants and for limited professional positions as junior geologists or geophysicists.

Geological Sciences Curriculum

The Department of Geological Sciences offers a bachelor of science (B.S.) or a bachelor of arts (B.A.) degree with a major in geological sciences.

Introductory Sequences. The department offers two introductory sequences. The recommended sequence for majors is Earth’s Interior Heat and Dynamics (GEOL 201), Earth Surface and Environmental Geology (GEOL 202), Evolution of the Earth (GEOL 203). The 100-level sequence—Earth’s Dynamic Interior (GEOL 101), Environmental Geology and Landform Development (GEOL 102), The Evolving Earth (GEOL 103)—may be substituted if the three courses are passed with grades of mid-B or better.

Grade Options and Standards. Undergraduate majors must take for letter grades (the pass/no pass option is not acceptable) all the courses required in their degree program. Required courses must be completed with grades of C– or better. Exceptions for honors students are noted under Honors in Geological Sciences.

Major Tracks. Earth science is an unusually broad subject. It addresses everything from the chemical processes that make rocks and minerals to the physics behind plate tectonics and the travel of earthquake shock waves through the planet. It explores the history of the evolution of life revealed in fossils, and it probes the earth processes that affect how humans can survive on the surface of the planet. To address this breadth, the department offers four curricular tracks for a major in geological sciences: geology, geophysics, environmental geoscience, and paleontology.

All of the tracks require a common core of general chemistry, calculus, general geology, and physics, except that paleontology-option students may take biology in place of physics.

Every track includes an introductory geology sequence. See Introductory Sequences above. The courses in each track are divided into three categories: core, additional requirements, electives.

Undergraduate Research. Up to 4 credits of research can be counted toward electives in any of the tracks. To receive such credit, students must (1) submit a short letter, written by the faculty research adviser and addressed to the head undergraduate adviser in geological sciences, stating the nature of the research and asserting that there is faculty supervision; and (2) submit a final written report to the faculty adviser describing the results of the research. Students may earn credit in this category by registering for any of the following: Research (GEOL 401), Field Studies (GEOL 406), Laboratory Projects (GEOL 408). Students who complete an honors thesis may not apply this option toward elective credits.

Graduate Studies [back to top]

The Department of Geological Sciences offers programs of graduate study leading to master of science (M.S.), master of arts (M.A.), and doctor of philosophy (Ph.D.) degrees with opportunity for research in a wide variety of specialty fields. Course work is designed to meet individual needs, and students may pursue independent research in geobiology, geochemistry, geodesy, geomechanics, geomorphology, geophysics, mineralogy, petrology, volcanology, paleontology, stratigraphy, sedimentary petrology, structural geology, and ore deposit geology. The master’s degree program requires two years or more for completion.

Admission to the graduate program is competitive and based on academic records, scores on the Graduate Record Examinations (GRE), and letters of recommendation. Nonnative speakers of English must also submit scores for the Test of English as a Foreign Language (TOEFL) and the Test of Spoken English (TSE). Applications are welcome from students who are interested in using their background in related fields, such as physics, chemistry, and biology, to solve geologic or geophysical problems.

Responsibility for advising graduate students lies with a guidance committee consisting of three faculty members. This committee meets with each student shortly after he or she arrives on campus and as often thereafter as necessary for planning purposes.

Requirements

Basic university requirements for graduate degrees are described in the Graduate School section of this catalog. The department sets additional examination, course work, seminar, and thesis requirements. Applicants should write to the Department of Geological Sciences for details.

Programs

Graduate study in geological sciences is offered in five broad areas: volcanology-petrology-geochemistry, stratigraphy–surface processes, paleontology-paleopedology-geobiology, structural geology–geophysics, and economic geology (mineral deposits).

Volcanology-Petrology-Geochemistry

The department has excellent analytical and other research facilities for studies in these subdisciplines, and the volcanic and metamorphic terranes of the Northwest offer unsurpassed opportunities for field studies. Active research programs are diverse and include studies of eruption dynamics, magma volatile inventories, and magma rheology; experimental studies of igneous phase equilibria and trace element partitioning; calculations of multicomponent equilibria in aqueous systems and volcanic gases; and studies of igneous protogenesis.

Stratigraphy-Surface Processes

The stratigraphic record of tectonically active sedimentary basins indicates the dynamic interactions among basin subsidence, sediment input from eroding sources, evolution of depositional systems, and active faulting and folding that govern these processes. Research in this area combines field-based stratigraphic, sedimentologic, and geomorphic analysis with provenance studies and concepts derived from theoretical models to decipher the complex structural and climatic controls on the filling histories of active basins.

Surface processes regulate how tectonics and climate affect landscape evolution. Field observations, numerical simulations, topographic analyses, and experimental facilities are used to study sediment transport processes over a range of spatial and temporal scales. Projects incorporate links between active tectonics and structural geology, biology, geomechanics and surface processes to address problems such as landsliding and hill-slope evolution, biological contributions to soil creep and landscape lowering, and the geomorphic implications of seismic-induced landsliding.

Paleontology-Paleopedology

Studies of fossil soils, plants, and vertebrates aim to reconstruct life on land and its role in global change. Global changes of interest include Neogene paleoclimate and paleoenvironment of ape and human evolution in East Africa, environmental effects of terminal Cretaceous impact and dinosaur extinction in Montana, consequences of mass extinction and methane clathrate degassing at the Permian-Triassic boundary, and the effect of early land plants and forests on weathering and atmospheric composition during the early Paleozoic.

Geobiology focuses on the interaction of microorganisms with the geologic environment and the ways life forms affect geological processes, such as weathering and mineralization.

Structural Geology-Geophysics

Graduate work in the structural geology-geophysics area involves the study of the earth’s dynamic processes

Seismic imaging techniques using regional arrays provide tools for understanding regional tectonics. Studies of upper-mantle and lithospheric structure beneath the Rocky Mountains and in the Pacific Northwest subduction zone are providing essential constraints, unavailable from surface geology, for detailed dynamical models of plate-lithospheric deformation.

Structural geology focuses on applying modern field and analytical techniques to solving problems in Cenozoic tectonics and active faulting. Detailed field mapping, trench logging, and geomorphic analysis are combined with seismic array data, land- and space-based geodetic data, and theoretical modeling to address problems including Oregon’s Basin and Range province and coastal deformation, active tectonics of the San Andreas Fault system, and seismic risk along the Pacific margin of the United States and southeast and central Asia.

Geophysical experiments conducted at sea investigate the nature of sea-floor spreading including the segregation, transport, and storage of melt; the rifting of oceanic lithosphere; and the spatial and temporal connectivity between magmatic, tectonic, and hydrothermal processes.

Mineral Deposits

Current research on ore deposits includes studies of porphyry copper deposits, epithermal veins, sediment-hosted base metal deposits, and active geothermal systems. These research efforts combine field mapping, petrography, and chemical analyses with theoretical chemical modeling of processes of ore fluid generation, alteration, and mineralization (e.g., red bed-brine reaction, boiling epithermal solutions, effects of cooling hydrothermal solutions).

Related Research Activities

The Condon Collection, administered by the geological sciences department and overseen by the Museum of Natural and Cultural History, contains an extensive collection of vertebrate fossils, paleobotanical specimens, and recent vertebrates that are available to interested researchers for study.

Research Facilities

Students may use a variety of analytical facilities and equipment including a three-component broadband (0.03–50Hz) seismic array, an electron microprobe, a scanning electron microscope with image analysis, x-ray diffraction, FTIR spectroscopy, stable isotope mass spectroscopy, and a geobiology laboratory.

An experimental petrology laboratory covers a range of crustal temperatures and pressures and includes equipment for doing experiments in controlled atmospheres. Two piston-cylinder apparatus with pressure-temperature capability to 35 kilobars and 1500° C may be used to study crystalline, partially molten, and molten silicates under mantlelike conditions.

Computers are used for much of the research in the department including acquisition and processing of seismic and gravity data and numerical modeling of geophysical processes and geochemical reactions. A geochemistry laboratory is equipped with sophisticated computer programs for thermodynamic calculations of gas-liquid-solid equilibria and reaction processes important in metamorphic, volcanic gas, hydrothermal, and diagenetic systems. The Internet can be accessed through the UONet fiber-optic link. A student computer facility, equipped with PC and Macintosh computers and laser printers, is also connected to the networks.

The sedimentological and paleontological laboratories have, in addition to standard laboratory equipment, an electronic particle-size analyzer, an x-radiography unit, photomicroscopes, a Leitz Aristophot unit, a fully maintained catalog of foraminifera, an acid room, and a conodont-processing laboratory.

Financial Aid for Graduate Students

The department provides support to a limited number of graduate students through graduate teaching fellowships. Other students receive research assistantships from individual faculty members whose research is supported by grant funds.

Most of the department’s graduate students are fully or partially supported through teaching and research assistantships. More information about financial assistance and department policies for awarding and renewing teaching and research fellowships may be obtained by writing to the department.
