Geology (GEO)
Paul Garvin (chair), Ray Rogers, Peter 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 300 level, one of which must be taught in the field, as GEO 321 (Field Geology), GEO 329 (Geology of a Region), 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, MAT 141, 142, and PHY 111, 112 (or 101, 102); 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 300 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.

Global pattern of volcanic activity, eruption types, volcanic products, form and structure of volcanoes, and interaction with humankind, including effects on climate and agriculture, relation to ore deposits, eruption prediction, and hazard mitigation. (Science) THOMPSON
104. Dinosaurs: A Case Study of Controversy in Science
The evolution, paleobiology, and paleoecology of the dinosaurs and their contemporaries, with an emphasis on current debates and controversies. Alternate years. (Science) ROGERS
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) ROGERS
114. Investigations in Geology
Elementary investigation of selected processes and phenomena in physical geology, emphasizing ``hands-on'' experience in combined field and laboratory settings. Not open to students previously enrolled in GEO 111. (Laboratory Science) GARVIN
211. Cartography
History and principles of map making, including projections. Maps as a measure of our changing global perspective. Practical work includes surveying, map design, drafting, and computer techniques. Limited enrollment. Alternate years. THOMPSON
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, 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) ROGERS
280. 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
308. Vertebrate Evolution
Five-hundred-million years of vertebrate evolution culminating in the origin of humans, tracing the geologic record of the generally accepted phylogeny of humans through fish, amphibians, reptiles, early mammals, and primates. Prerequisites: GEO 111, 112. Alternate years. (Science) ROGERS
312. Mineralogy II: Applications
Methods of mineral analysis. Applications of principles of mineralogy to an understanding of mineral properties, minerals as gems, mineral resources, and minerals and human health. Practical exercises in x-ray powder diffraction. Field-and-laboratory-based comparative study of mineral deposits in eastern Iowa. Prerequisite: GEO 212. (Laboratory Science) GARVIN
315. Structural Geology II
Descriptive, kinematic, and dynamic analysis of faults, joints, folds, foliation, and lineation. Mechanics of rock deformation. Geologic map interpretation and cross-section construction. Four-day field trip to Wisconsin or Missouri may entail some additional costs. Prerequisite: GEO 215. (Laboratory Science) THOMPSON
