Geology (GEO)
Paul Garvin, Benjamin Greenstein, Peter Thompson (chair)
Adjunct Faculty/Academic Staff: Thelma Thompson
Major: A minimum of 11 courses, including GEO 111, 112, 212, 215, 217, 316, 319, 324; plus three elective courses at or above the 200 level, one of which must be taught in the field, as GEO 255, 321, 329, or an accredited summer field camp. Supporting coursework in chemistry, physics, and mathematics is strongly recommended. Students planning to pursue geology at the graduate level should also take GEO 312, 315, an accredited summer field camp; CHE 121-122 (Chemical Principles I and II); MAT 141-142 (Calculus I and II); and PHY 111-112 (General Physics I and II), or 101-102 (Introductory Physics I and II); also an intermediate-level course in a foreign language.
Teaching Major: GEO 111, 112, 212, 215, 217, and three additional Geology courses at or above the 200 level; and PHY 221 (Astronomy) or 228 (Energy Alternatives). Supporting work in the other sciences and mathematics is strongly recommended. In addition to the foregoing requirements, prospective teachers must also apply for admission to the Teacher Education Program (preferably at the start of their sophomore year) and complete a second major in Secondary Education, as described under Education.
Minor: A minimum of seven course credits in Geology which include GEO 111, 112, 212, 215, 217, and two electives which must be at or above the 200 level. Supporting coursework in other sciences and mathematics is recommended. Environmental Studies majors may receive a minor in Geology only if the two elective Geology courses are not counted toward the Environmental Studies major.

105. Marine Science
An introduction to the global marine environment, with emphasis on sea
floor dynamics, submarine topography and sediments, the nature and
circulation of oceanic waters, coastal processes, marine biologic
productivity, coral reefs and pollution, and exploitation of the oceans
by humans. One field trip to the Shedd Aquarium, Chicago. (Science)
GREENSTEIN
111. Physical Geology
The earth as a dynamic body whose materials and structures are continually being modified by the interactions of the geological processes, emphasizing interrelationships between geological processes and human activity. Field trips. (Laboratory Science) GARVIN or THOMPSON
112. Historical Geology
Origin
and evolution of the solid earth, atmosphere, and ocean; the origin of
life; and the succession of life through geologic time. Prerequisite:
either GEO 101, 111, or 114. (Laboratory Science) GREENSTEIN
114. Investigations in Geology
Elementary-level field- and laboratory-based investigations of rocks,
minerals, and fossils. The information obtained will be used to
interpret their histories. Not open to students previously enrolled in GEO
111. (Laboratory Science) GARVIN
212. Mineralogy I: Principles
Principles and processes of mineral growth; mineral chemistry and structure; physico-chemical stabilities of minerals; the foregoing leading to an understanding of the origins of minerals. Laboratory problems and mineral identification. Prerequisites: CHE 121 and GEO 111. (Laboratory Science) GARVIN
215. Structural Geology I
Descriptive analysis of rock structures: faults, joints, folds, unconformities, and intrusive igneous contacts. Trigonometric solutions to three-dimensional problems. Use of the Brunton compass. Prerequisites: GEO 111 and 112. (Laboratory Science) THOMPSON
217. Paleontology
Principles of
paleontology, paleoecology, and taxonomy, with an introduction to major
fossil invertebrate groups. Prerequisite: GEO 112. (Laboratory Science) GREENSTEIN
220. Resources and Land Use
Mineral resource acquisition and utilization in relation to land use. Competing land use issues, such as: mining vs. wilderness preservation; soils and agriculture vs. urban encroachment; coastal resources vs. urban encroachment. The role of geology in comprehensive land use planning. Prerequisite: either GEO 101, 111, or 114. Alternate years. (Science) GARVIN
255. Modern and Ancient Carbonate Systems of the Bahamas
Field course on the geologic and biologic processes occurring in a modern carbonate system and the responses preserved in Pleistocene limestones. Days spent in the field investigating modern shallow marine environments (coral reefs, tidal flats, lagoons, beaches, dunes) and ancient analogs preserved in rock outcrops, caves and sink-holes. Follow-up lectures and laboratory sessions in the evening. Snorkeling experience desirable but not essential, SCUBA diving opportunities will be made available. Taught at the Bahamian Field Station, San Salvador Island, Bahamas. May entail additional costs. (Laboratory Science) GREENSTEIN
