Industrial pollution, agricultural pesticides and fertilizers, and fossil fuel waste-products are major sources of biotoxic and phytotoxic heavy metals (e.g., As, Cd, Cu, Hg, Mo, Ni, Pb, Sb, Sc, Tl) in the environment. The mobilities and pathways of these elements into-and-through soil and groundwater are examined. Analytic methods and sampling strategies for tracing the historical trends of heavy metal fluxes in specific geographic regions are explored. Prerequisite: Permission of the instructor. To be offered every-other year. Fall semester.

Prerequisite: Permission of Instructor.
Geo 528 (Bio 528) Origins and Extinctions (3)
Detailed consideration of the data, interpretations and controversies associated with the evolution of the Earth and its biosphere, including cosmochemistry, planetary accretion, plate tectonics, biological evolution, and mass extinctions. Preparation and submission of a graduate-level literature research paper required. Prerequisite: Graduate standing and consent of instructor.
Geo 535 Surficial Applied Geohydrology (3)
Classification, origin, and properties of surficial materials; sampling and exploration methods; determination of groundwater and hydrologic properites; groundwater flow systems and introduction to modeling, hydrochemistry, geological factors in environmental studies with respect to remediation and regulatory policy, exercises in surficial well logging, pump test analysis, and brief research papers. Three lectures each week. One or two optional half-day field trips. Spring Semester.
Geo 541 Structural Geology II (3)
Introduction to selected topics in mechanics including stress, strain, and stress-strain relations.
Geo 545 Structural Geology III (4)
Structural analysis, mechanisms of rock fracture and flow, interpretation of regional stress and strain history from structural features. A term paper and oral presentation required. Prerequisite: Consent of instructor.
Geo 550 Climate Change (3)
This class is designed to introduce the field of Paleoclimatology and will specifically focus on the use of sediments and biological and geological archives to reconstruct environmental, climatic, and oceanographic change over a range of time scales with focus on the latest Pleistocene and Holocene In the process we will cover a range of topics in lecture that will provide an introduction to climatology, age dating techniques, climatic proxies (tracers), micropaleontology, and time-series analysis. In addition to lectures, the class will involve review of current scientific studies, a class presentation by each student, and a review paper on a relevant topic of choice. 3 lectures each week
Geo 566 Marine/Estuary Systems (3)
This class is designed as an in-depth study of marine and estuary systems with a focus on marine/estuary sedimentology and biogeochemistry. Additional study of lacustrine systems will be integrated into the class. In addition to lectures, the class will involve review of current scientific studies, a class presentation by each student, and a review paper on a relevant topic of choice. 3 lectures each week.

Use of chemical compositions and isotope abundances to acquire an understanding of the provenance and tectonic setting of sedimentary rocks. Prerequisite: Geo 512.
Geo 620 Tectonics II (3)
Study of the tectonic evolution of the earth's crust from the Mesozoic to Recent. Prerequisite: Geo 517 or consent of instructor.
Geo 640 Cosmochemistry (3)
Cosmic abundances (elemental and isotopic) and their usefulness in constraining the origins of major chemical systems on planets. Specific topics include core/mantle equilibrium within the earth; origin of atmosphere/hydrosphere on Venus, Earth, and Mars; origin of the earth's moon; and origin of differentiated meteorites. Prerequisite: Consent of instructor.
Geo 650 Isotope Geochemistry (3)
Chemical evolution of the earth, including nucleosynthesis, nebular condensation, and development of the crust/mantle/core. Emphasis on evidence from trace-element and isotope geochemistry. Prerequisite(s): Geo 510 and 515, or consent of instructor.
