GS 5: Living on the Edge (EARTH 15)

A weekend field trip along the Pacific Coast. Tour local beaches, geology, and landforms with expert guides from the School of Earth, Energy & Environmental Sciences. Enjoy a BBQ dinner and stay overnight in tents along the Santa Cruz coast. Get to know faculty and graduate students in Stanford Earth. Requirements: Two campus meeting and weekend field trip (Fall Quarter: October 14-15 OR October 21-22) to Pacific Coast. Enrollment limited to 25. Freshman have first choice. If you are interested in signing up for the course, complete this form: http://web.stanford.edu/~aferree/GS5.fb. The form will open August 1st.
Terms: Aut, Spr | Units: 1 | Grading: Satisfactory/No Credit

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
Instructors: Grove, M. (PI)

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 135: Sedimentary Geochemistry and Analysis (GS 235)

Introduction to research methods in sedimentary geochemistry. Proper laboratory techniques and strategies for generating reliable data applicable to any future labwork will be emphasized. This research-based course will examine how the geochemistry of sedimentary rocks informs us about local and global environmental conditions during deposition. Students will collect geochemical data from a measured stratigraphic section in the western United States. These samples will be collected during a four-day field trip at the end of spring break (attendance encouraged but not required). In lab, students will learn low-temperature geochemical techniques focusing on the cycling of biogeochemical elements (O, C, S, and Fe) in marine sediments throughout Earth history. The focus will be on geochemistry of fine-grained siliciclastic rocks (shale) but the geochemistry of carbonates will also be explored. This is a lab-based course complemented with lectures.
Terms: Spr | Units: 4 | Grading: Letter or Credit/No Credit
Instructors: Sperling, E. (PI)

GS 135A: Sedimentary Geochemistry Field Trip

Field trip to a sedimentary succession of geobiological interest. Students will measure the stratigraphic section, describe any fossils and trace fossils, and collect samples for geochemical analysis. Offered over spring break.
Terms: Spr | Units: 1 | Grading: Satisfactory/No Credit
Instructors: Sperling, E. (PI)

GS 167: Technology and National Security (GS 267, MS&E 193, MS&E 293)

Explores the relation between technology, war, and national security policy from early history to modern day, focusing on current U.S. national security challenges and the role that technology plays in shaping our understanding and response to these challenges. Topics include the interplay between technology and modes of warfare; dominant and emerging technologies such as nuclear weapons, cyber, sensors, stealth, and biological; security challenges to the U.S.; and the U.S. response and adaptation to new technologies of military significance.
Terms: Spr | Units: 3 | UG Reqs: WAY-SI | Grading: Letter or Credit/No Credit

GS 180: Igneous Processes (GS 280)

For juniors, seniors and beginning graduate students in Earth Sciences. Structure and physical properties of magmas; use of phase equilibria and mineral barometers and thermometers to determine conditions of magmatic processes; melting and magmatic lineages as a function of tectonic setting; processes that control magma composition including fractional crystallization, partial melting, and assimilation; petrogenetic use of trace elements and isotopes. Labs emphasize identification of volcanic and plutonic rocks in thin section and interpretation of rock textures. Prerequisite 102, 103, or consent of instructor.
Terms: Spr | Units: 4 | Grading: Letter (ABCD/NP)
Instructors: Stebbins, J. (PI)

GS 184: Field Trip to Volcanoes of the Eastern Sierran Volcanism

Four-day trip over Memorial Day weekend (involving light hiking and camping) to study silicic and mafic volcanism in the eastern Sierra Nevada: basaltic lavas and cinder cones erupted along normal faults bounding Owens Valley, Long Valley caldera, postcaldera rhyolite lavas, hydrothermal alteration and hot springs, Holocene rhyolite lavas of the Inyo and Mono craters, subaqueous basaltic and silicic eruptions of Mono Basin, floating pumice blocks. If snow-level permits, granites of Yosemite and/or silicic volcanism associated with the Bodie gold district. Recommended: 1 or equivalent. Limited enrollment; preference to frosh, sophs, and undergraduates and graduates majoring in SE3.
Terms: Spr | Units: 1 | Grading: Satisfactory/No Credit
