Course Descriptions
100. Principles of Geology (1). Introduction to the study of the Earth, including its structure, composition, and processes that act upon it. Focus is placed on how scientific methods can be used to decipher complex interactive processes, developing skills for observation and analysis in the field and laboratory. Lecture, laboratory, field study. One Saturday or Sunday field trip. Students who have credit for Geology 110 may not take this course for credit. Offered yearly.
105. Evolution of the Earth (1). The recent revolution in geologic thinking that was brought about by the ideas of sea-floor spreading, heat flow through the Earth's crust, reversals of the Earth's magnetic field, and earthquake studies allows a synthesis of the Earth's evolution. Information from rock associations, fossils, stratigraphic correlations, and radioactive-age determinations forms a logical picture of the co-evolution of the Earth's lithosphere, hydrosphere, atmosphere, and biosphere. The human dimension of historical geology is revealed in tracing the development of the concept of time. Lecture, discussion, laboratory, field study. One Saturday or Sunday field trip. Offered each spring.
110. Environmental Geology and Geologic Hazards (1). Application of geologic principles to help in understanding the response of our environment to natural and anthropogenic forces of change, and proper constraints we should exercise in being good stewards of the Earth. Natural resources, floods, volcanic activity, earthquakes, landslides, coastal processes, and pollution are among topics considered, with emphasis on current events. Lecture, discussion, laboratory, field study. One Saturday or Sunday field trip. Students who have credit for Geology 100 may not take this course for credit. Offered yearly.
171. Field Excursion Seminar (1/4, 1/2). The geology, geography, history, and environment of a region to be studied during an extended field excursion. A student may take the seminar for credit more than once. Graded credit/no credit at discretion of instructor. Prerequisite or co-requisite: Geology 100 or 105 or 110.
200. Mineralogy (1). The study of minerals, including their composition, properties, occurrence, and classification. Lectures and laboratory include discussion of basic crystallography and crystal chemistry, and introduction to optical mineralogy and the properties and occurrences of common rockforming minerals. Lecture, laboratory, field study. Offered each fall. Prerequisite or co-requisite: Geology 100 or 110.
205. Petrology (1). The study of rocks, including their composition, classification, and tectonic setting. Lectures and laboratory focus on the processes that control the formation of rocks in the context of plate tectonics and planetary evolution. Lecture, laboratory, field study. Offered each spring. Prerequisite: Geology 200.
210. Paleontology (1). The history of life from its origins to the present. The preservation, distribution, and identification of invertebrate fossils and of selected vertebrate and plant fossils. Competing evolutionary theories are evaluated in the perspective of geologic time. Fossils are studied as once-living organisms adapting to changing ecosystems. Lecture, discussion, laboratory, field study. (Also listed as Biology 210.) Offered even years, fall semester. Prerequisite: Geology 105 or Anthropology 120 or one course in biology. Geology 100 or 110 recommended.
215. Field Geology (11/2). Techniques of collecting, recording, and presenting geologic data. The use of the Brunton compass, magnetometer, GPS, surveying techniques, and surface and groundwater hydrogeology field meth ods. The interpretation of data as plotted on maps, sections, and aerial photographs. Field observations and measurements are synthesized with maps and cross-sections in written reports. Lecture, laboratory, field study. Sixweek course offered odd years, summer. Prerequisite: Two units in geology.
220. Structural Geology (1). Mechanical principles applied to folds, faults, joints, igneous plutons, and secondary structural features of the Earth. Laboratory study of deformative processes by models and experiments, and analysis of structures by graphical, mathematical, and computer techniques. Lecture, laboratory, field study. Offered odd years, spring semester. Prerequisite: Geology 100 or 110 and 200.
230. Sedimentology (1). The origin, distribution, deposition, and lithification of common rock-forming sediments. Lectures, laboratories, and field work consist of collecting and analyzing data and determining the geologic history and significance of sediments and sedimentary rocks by means of the binocular and petrographic microscopes and various mechanical and computer techniques. (WL) Offered even years, fall semester. Prerequisite: Geology 100 or 110; Geology 105 and 200 highly recommended.
235. Geomorphology (1). This course focuses on the origin and development of landforms created by fluvial, glacial, eolian, and karst processes. In addition, the relationships of landforms to underlying geologic structures and the history of geologic and climate changes as recorded by surface features are explored. Landscapes and surface processes are analyzed using air photos and topographic maps as well as fieldmapping techniques and geographic information systems. (WL) Offered each fall. Prerequisite: Geology 100 or 110.
240. Hydrogeology (1). An introduction to the components of the hydrologic cycle with an emphasis on the movement of water through geologic media. Field-monitoring methods and analysis of hydrogeologic data through graphical, mathematical, and computermodeling techniques. Applications to issues of water quality, water supply, and water resources management. Lecture, laboratory, field study. Offered even years, spring semester. Prerequisite: Geology 100 or 110; Mathematics 110 highly recommended.
250, 251. Advanced Topics in Geology (1/2, 1). Topics of current interest or of special importance in the field of geology chosen to take advantage of the expertise of either the regular faculty or of visiting lecturers. Topics course. Prerequisite: Dependent upon subject matter.
325. Tectonics (1). The structural and chemical evolution of the continental lithosphere from the Archean to present. Lectures and laboratory focus on the kinematics of plate motions, continental growth, geochronology, geothermobarometry, and thermal modeling. Mountain belts from Earth, Venus, and Mars are used as case studies. Basic computer and mathematical skills, including calculus, are expected. (WL) Offered occasionally. Prerequisite: Geology 205, 220; Mathematics 110; or consent of instructor.
