4.00 Credits
This course entails the study of the composition and texture of sedimentary rocks, with particular emphasis on thin section petrography. The primary focus of the course is analysis of the mineral composition, texture and porosity of sedimentary rocks. Chemical and physical weathering, erosion, deposition, compaction, lithification and diagenesis are discussed in detail. Laboratory work stresses thin section observation of sandstone and carbonate rocks, as well as making thin sections from hand specimens. Prerequisite: Geology 216.

4.00 Credits
Micropaleontology is the branch of the earth sciences that deals with fossil organisms too small to resolve in detail with the unaided eye. This course introduces students to the broad range of micropaleontological techniques and to the numerous groups of fossils on which these are practiced. Microfossils are the basis for most synthesis of global climate change, biostratigraphy of ocean basins and regional and global rock correlation. The modern time scale is built on them. Both light and scanning electron microscopy are employed by students in the course. Prerequisite: Geology 206 or permission of the instructor.

4.00 Credits
A major responsibility of all scientists, regardless of their employment, is to convey the technical results of their work to any of several audiences in a factual, informative and accurate manner. Most of this process requires particular writing skills. In geology these are combined with a wide range of graphics techniques around which text is often formed, with unique methods of reference citation and the need for careful attention to the ethics of ideas and their attribution.

4.00 Credits
This course provides an introduction to the movement and storage of water on the Earth's surface (hydrology) and in the subsurface (hydrogeology). We discuss the fundamentals of the water cycle and hydrologic processes at the surface, the transfer of water in and out of the subsurface and the processes of groundwater flow. Human impacts upon water are also examined, including water resources, contamination, changing land use and climate change. Prerequisite: Geology 103. Also offered as Environmental Studies 319.
-
4.00 Credits
Field-based studies form the core of geological inquiry. The purpose of this course is to enrich students' understanding of the process of conducting geological research in the field. The course consists of on-campus trip preparation and data analysis and reporting, and a field trip lasting approximately two weeks. Field trip locations and topics vary. Students may be responsible for some costs. Prerequisite: Geology 103 or permission of instructor.
-
4.00 Credits
Geochemistry is the study of the distribution, concentration and cycling of the elements in Earth materials. The course explores the composition and origin of the solar system and Earth's lithosphere, hydrosphere and atmosphere. It focuses on the tools utilized by geochemists, including major, trace and rare earth element analyses, stable and radiogenic isotopes, geochronology, and sampling methods and retrospective studies, and introduces new and emerging concerns in environmental geochemistry. The use, misuse and presentation of chemical analyses are explored in detail. Prerequisites: Geology 203, Chemistry 103 and 104 or 105, or the permission of the instructor.
-
4.00 Credits
The deformation of rocks through brittle and ductile processes is the focus of structural geology. This course examines how forces such as those associated with plate tectonics and mountain- building are recorded in rocks on the regional, outcrop and microscopic scale. The genesis, recognition and classification of structures such as folds, faults, joints and microstructures as well as the mechanical behavior of rocks, and stress and strain are studied as important components in deciphering the tectonic and deformational history of an area. The laboratory emphasizes application of theory to field problems. Prerequisite or co-requisite: Geology 203 or permission of instructor. Also offered through Outdoor Studies.
-
4.00 Credits
Semester-long studies in appropriate areas of the earth sciences may be designed in consultation with an individual instructor in the geology department. May use seminar format when appropriate. Permission of instructor and junior standing are required.
-
0.50 - 3.00 Credits
Detailed instruction in the use of a scanning electron microscope (SE M) and support techniques such as critical point drying, specimen coating (standard vacuum and sputter coating), specimen fixation, black and white photographic techniques and computer image acquisition and analysis. The theory and practice of energy dispersive x-ray analysis (EDAX) for determining atomic element makeup and element mapping will also be learned. Prerequisite: any 200- or 300-level science course or permission of the instructor. Also offered as Biology 391.
-
4.00 Credits
This course places dual emphasis on stratigraphic principles and practices. Major accent is given to stratigraphic nomenclature, interpretation of sedimentary facies and sequences, evaluation of geologic contacts and the use of stratigraphic indices. These concepts are applied through laboratory work to field descriptions of stratigraphic sections, correlation techniques in practice, production of derivative maps from surficial and subsurface data and the use of stratigraphy as a tool by the economic geologist. Labs employ modern computer graphics and plotting methods whenever possible. Prerequisite: senior standing.
