GS 4: Coevolution of Earth and Life (EARTHSYS 4)

Earth is the only planet in the universe currently known to harbor life. When and how did Earth become inhabited? How have biological activities altered the planet? How have environmental changes affected the evolution of life? Are we living in a sixth mass extinction? In this course, we will develop and use the tools of geology, paleontology, geochemistry, and modeling that allow us to reconstruct Earth¿s 4.5 billion year history and to reconstruct the interactions between life and its host planet over the past 4 billion years. We will also ask what this long history can tell us about life¿s likely future on Earth. We will also use One half-day field trip.

GS 40N: Diamonds

Preference to freshmen. Topics include the history of diamonds as gemstones, prospecting and mining, and their often tragic politics. How diamond samples provide clues for geologists to understand the Earth's deep interior and the origins of the solar system. Diamond's unique materials properties and efforts in synthesizing diamonds.

GS 42: Landscapes and Tectonics of the San Francisco Bay Area (EARTH 42)

Active faulting and erosion in the Bay Area, and its effects upon landscapes. Earth science concepts and skills through investigation of the valley, mountain, and coastal areas around Stanford. Faulting associated with the San Andreas Fault, coastal processes along the San Mateo coast, uplift of the mountains by plate tectonic processes, and landsliding in urban and mountainous areas. Field excursions; student projects.

GS 55Q: The California Gold Rush: Geologic Background and Environmental Impact

Preference to sophomores. Topics include: geologic processes that led to the concentration of gold in the river gravels and rocks of the Mother Lode region of California; and environmental impact of the Gold Rush due to population increase, mining operations, and high concentrations of arsenic and mercury in sediments from hard rock mining and milling operations. Recommended: introductory geology.

GS 90: Introduction to Geochemistry (EARTHSYS 90)

The chemistry of the solid earth and its atmosphere and oceans, emphasizing the processes that control the distribution of the elements in the earth over geological time and at present, and on the conceptual and analytical tools needed to explore these questions. The basics of geochemical thermodynamics and isotope geochemistry. The formation of the elements, crust, atmosphere and oceans, global geochemical cycles, and the interaction of geochemistry, biological evolution, and climate. Recommended: introductory chemistry.

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.

GS 103: Earth Materials: Rocks in Thin Section (GS 203)

Use of petrographic microscope to identify minerals and common mineral associations in igneous, metamorphic, and sedimentary rocks. Crystallization histories, mineral growth and reaction relations, deformation textures in metamorphic rocks, and provenance of siliciclastic rocks. Required lab section. Prerequisite 102.
Terms: Win | Units: 3 | UG Reqs: WAY-SMA | Grading: Letter (ABCD/NP)
Instructors: Miller, E. (PI)

GS 105: Introduction to Field Methods

Two-week, field-based course in the White Mountains of eastern California. Introduction to the techniques for geologic mapping and geologic investigation in the field: systematic observations and data collection for lithologic columns and structural cross-sections. Interpretation of field relationships and data to determine the stratigraphic and deformational history of the region. Prerequisite: GS 1, recommended: GS 102.
Terms: Aut, Spr | Units: 3 | UG Reqs: 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.
Terms: Win | Units: 4 | UG Reqs: GER: DB-NatSci, WAY-SMA | Grading: Letter or Credit/No Credit

GS 110: Rock Deformation 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 zones 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, 105.
