3.00 Credits
This course provides an overview of the Earth for the past 4.6 billion years. Students explore the concept of geologic time as they delve into the vast past of our evolving planet. Major emphasis is placed on tracking the evolution of life, from the simplest single-celled organisms of the ancient Earth to today's diverse floras and faunas. Another major focus is the linkage among abiotic and biotic systems-the lithosphere, atmosphere, hydrosphere, and biosphere did not and do not evolve independently. The laboratory component of this course is designed to familiarize students with the rocks and fossils that archive the history of Earth. The class includes a fossil-collecting field trip. Required for geology majors. Three hours lecture and two and a half hours lab per week. No prerequisites. Every spring. (4 credits) 200 FIELD EXCURSION SEMINAR The geology and geography of a region will be studied during a geologic field excursion to a selected destination. The excursion will be preceded by a seminar course that includes readings and oral presentations. A student may take the seminar more than once for credit. Prerequisite: Geology 150 or 155 or permission of instructor. Alternate years. (2 credits)

3.00 Credits
This course focuses on the geology of a foreign country or a region of the U.S. It also includes a study of the geography and culture of the region. It is designed as a January course. Participants meet prior to departure in order to learn necessary background information. The field excursion generally spans two to three weeks. The region to be studied will be different each year and a student may take the course more than once for credit. This course is offered on a pass/fail basis. Prerequisite: Permission of instructor(s). Offered occasionally. (2 credits)

3.00 Credits
This course examines the relationships between symmetry, chemistry, physical and optical properties, and occurrence of minerals. General cosmochemistry, geochemistry and crystal growth will also be discussed. Laboratory projects include crystal morphology and symmetry, optical mineralogy, x-ray diffraction, wet chemistry, and the identification of common rock-forming minerals. Three hours lecture and three hours lab per week. Field trips. Prerequisites: Geology 150 and one course in chemistry or permission of instructor. Fall semester. (4 credits)
-
3.00 Credits
This course focuses on the primary and secondary structures of rocks, the mechanics of rock deformation, and global tectonics. Discussions focus on the origins and interpretations of major rock features using hand samples and thin sections. Problem sets use graphical techniques to solve structural problems. This course also provides an introduction to map interpretation and mapping techniques. Three hours lecture and three hours lab per week. Field trips. Prerequisites: Geology 150 and 155. Spring semester. (4 credits)

3.00 Credits
Geomorphology is the study of physical, chemical, and biological processes that occur on the surface of a planetary body. We will be examining the processes that turn solid rock into transportable material, the transport mechanisms themselves (whether beneath glaciers, down hillslopes, or in rivers), and the patterns of deposition, many of which are unique to the processes that created them. These processes range from the very large (volcanism and mountain-building) to the microscopic (frost cracking of rock, soil creep, and chemical weathering along mineralogic grain boundaries). Some processes occur frequently across geographic boundaries and throughout geologic time (like rainsplash), while others are stochastic in nature and dramatic in their geomorphic signature (like glacial outburst floods). We will focus on the roles of rivers, glaciers, and mass movements in shaping landscapes, but will examine wide-ranging landscapes such as arid environments and coastal regions. The study of current surface processes on the Earth will be examined with an eye toward understanding the evolution of landscapes over geologic timescales. Prerequisite: Geology 150 or permission of instructor. Fall semester. (4 credits)
-
3.00 Credits
This course focuses on sedimentary rocks and the stratigraphic record. Topics covered include the origin and classification of sediments and sedimentary rocks (siliciclatic and carbonate), sedimentary structures (physical and biogenic), diagenesis, and basin analysis. Students are introduced to the principles and practice of stratigraphy (including the latest applications of sequence stratigraphy). Emphasis is placed on the interpretation of ancient sedimentary environments. Three hours lecture and three hours lab per week. Field trips. Prerequisite: Geology 155 or permission of the instructor. Spring semester. (4 credits)
-
1.00 - 3.00 Credits
This course surveys the long history of life, as recorded by the fossil record. Students are introduced to the morphology and paleoecology of the major fossil groups (invertebrates and vertebrates) through discussions, labs, and readings. Students also learn the methods used to study the paleobiology and evolution of extinct organisms. Three lectures and one three-hour lab per week. Local field trips. Prerequisite: Geology 155 or permission of the instructor. Fall semester. (4 credits)
-
4.00 Credits
Lecture and reading topics will include comparative planetary evolution, earth's physical fields (gravitational, magnetic, electrical), seismology, seismic interpretation, the geoid, rock magnetism and paleomagnetics, heat flow, earth structure and a discussion of exploration geophysical methods. Lab and lab project. Fall semester. (4 credits)
-
3.00 Credits
This course focuses on the classification, occurrence, and origin of igneous, metamorphic, and sedimentary rocks. Emphasis will be placed on the relationships between lithology, geochemistry, and tectonic setting. Laboratory exercises include hand specimen identification, thin-section interpretation, textural analysis, major and trace element modeling, SEM/EDS and XRF analysis. Students participate in a semester-long research project on a local geological feature. Three hours lecture and three hours lab per week. Field trips. Prerequisite: Geology 250. Spring semester. (4 credits)
-
3.00 Credits
Senior geology majors will participate with faculty and staff in readings, presentations, and discussions of pertinent geological topics (e.g. plate tectonics, global change, mass extinction). The historical and philosophical roots of geology will be examined. Potential field trips. Prerequisite: senior standing in geology or permission of instructor. Spring semester. (1 credit)
