GS 102: Earth Materials: Introduction to Mineralogy

The minerals and materials that comprise the earth and their uses in modern society. How to identify, classify, and interpret rock-forming minerals. Emphasis is on information provided by common minerals about the nature of the Earth's interior and processes such as magmatism and metamorphism that operate there, as well as the major processes of weathering and erosion that link plate tectonics to earth cycles. Required lab section. Prerequisite: introductory geology course. Recommended: introductory chemistry.
Terms: Aut | Units: 4 | UG Reqs: GER: DB-NatSci, WAY-SMA | Grading: Letter or Credit/No Credit

GS 106: Sedimentary Geology and Depositional Systems

Topics: weathering, erosion and transportation, deposition, origins of sedimentary structures and textures, sediment composition, diagenesis, sedimentary facies, tectonics and sedimentation, and the characteristics of the major siliciclastic and carbonate depositional environments. Required Lab Section: methods of analysis of sediments in hand specimen and thin section. There is a required field problem trips to the field site(s) during the quarter, data collection and analysis, and preparation of a final written and oral report. Prerequisites: 1, 102, 103.

GS 110: Structural Geology and Tectonics (GS 294)

Theory, principles, and practical techniques to measure, describe, analyze, and interpret deformation-related structures on Earth. Collection of fault and fold data in the field followed by lab and computer analysis; interpretation of geologic maps and methods of cross-section construction; structural analysis of fault zone and metamorphic rocks; measuring deformation; regional structural styles and associated landforms related to plate tectonic convergence, rifting, and strike-slip faulting; the evolution of mountain belts and formation of sedimentary basins. Prerequisite: GS 1, calculus. Recommended: 102.
Terms: Spr | Units: 3-5 | UG Reqs: GER: DB-NatSci | Grading: Letter (ABCD/NP)
Instructors: Hoiland, C. (PI)

GS 115: Engineering Geology and Global Change (CEE 196)

The application of geology and global change to the planning, design, and operation of engineering projects. Case histories taught in a seminar setting and field trips emphasize the impact of geology and global change on both individual engineering works and the built environment by considering Quaternary history and tectonics, anthropogenic sea level rise, active geologic processes, engineering properties of geologic deposits, site exploration, and professional ethics. Prerequisite: GS 1 or consent of instructor.
Terms: not given this year | Units: 3 | UG Reqs: GER: DB-NatSci | Grading: Letter or Credit/No Credit

GS 123: Evolution of Marine Ecosystems (BIO 119, EARTHSYS 122, GS 223B)

Life originally evolved in the ocean. When, why, and how did the major transitions occur in the history of marine life? What triggered the rapid evolution and diversification of animals in the Cambrian, after more than 3.5 billion years of Earth's history? What caused Earth's major mass extinction events? How do ancient extinction events compare to current threats to marine ecosystems? How has the evolution of primary producers impacted animals, and how has animal evolution impacted primary producers? In this course, we will review the latest evidence regarding these major questions in the history of marine ecosystems. We will develop familiarity with the most common groups of marine animal fossils. We will also conduct original analyses of paleontological data, developing skills both in the framing and testing of scientific hypotheses and in data analysis and presentation.

Topics: precipitation, evapotranspiration, infiltration and vadose zone, groundwater, surface water and streamflow generation, and water balance estimates. Current and classic theory in soil physics and hydrology. Urban, rangeland, and forested environments.
Terms: not given this year | Units: 3 | UG Reqs: GER: DB-NatSci, WAY-SMA | Grading: Letter (ABCD/NP)

GS 131: Hydrologically-Driven Landscape Evolution

Materials of the Earth and hydrologically driven landscape processes. Topics: hillslope hydrology, weathering of rocks and soils, erosion, flow failures, mass wasting, and conceptual models of landscape evolution. Current and classic theory in geomorphology.
Terms: not given this year | Units: 3 | UG Reqs: GER: DB-NatSci, WAY-SMA | Grading: Letter (ABCD/NP)

GS 170: Environmental Geochemistry (EARTHSYS 170, GS 270)

Solid, aqueous, and gaseous phases comprising the environment, their natural compositional variations, and chemical interactions. Contrast between natural sources of hazardous elements and compounds and types and sources of anthropogenic contaminants and pollutants. Chemical and physical processes of weathering and soil formation. Chemical factors that affect the stability of solids and aqueous species under earth surface conditions. The release, mobility, and fate of contaminants in natural waters and the roles that water and dissolved substances play in the physical behavior of rocks and soils. The impact of contaminants and design of remediation strategies. Case studies. Prerequisite: 90 or consent of instructor.
Terms: not given this year | Units: 4 | UG Reqs: GER: DB-NatSci | Grading: Letter (ABCD/NP)

GS 171: Geochemical Thermodynamics

Introduction to the application of chemical principles and concepts to geologic systems. The chemical behavior of fluids, minerals, and gases using simple equilibrium approaches to modeling the geochemical consequences of diagenetic, hydrothermal, metamorphic, and igneous processes. Topics: reversible thermodynamics, solution chemistry, mineral-solution equilibria, reaction kinetics, and the distribution and transport of elements by geologic processes. Prerequisite: GS 102.

GS 185: Volcanology (GS 285A)

For juniors, seniors, and beginning graduate students. Eruptive processes that create volcanic deposits and landforms; shield, stratocone, and composite volcanoes, lava dome fields; calderas. Control of magma viscosity and water content on eruptive style. Fluid dynamic controls on the characteristics of lavas and pyroclastic flows. Submarine and subglacial eruptions and interaction of magma with groundwater. Rhyolitic supereruptions and flood basalts: effects on climate and atmospheric chemistry, relation to extinction events.
