51-109 - Evolution of the Earth, 4 credits, Fall-Spring. Historical geology with emphasis on global geologic processes (such as plate tectonics, geochemical cycles, paleoclimate, sea levle change etc.) and the geologic history of North America. History of life as revealed in the geologic record. A field trip to the Devil's Lake area is required. Satisfies general education requirements in laboratory science. Prerequisite: Geology 102, 110 or 150. Syllabus; Lecture and Lab schedule, Study Guides, Baraboo field trip.
51-309 - Paleontology, 3 credits, Fall. Morphology, classification, life environment, and stratigraphic distribution of invertebrate fossils. Fossil preservation and nature of the fossil record. Mechanisms of organic evolution and extinction. Application of paleontologic principles (such as biostratigraphy, paleoecology) to the study of earth history. Prerequisite: Geology 109. Syllabus, Course field trip to Northeast Iowa.
51-311 - Stratigraphy and Basin Analysis, 3 credits, Spring-odd years. Application of stratigraphic concepts to the study of basin evolution and the genesis and architecture of sedimentary rock successions. Discussion of the tectonic evolution of basins, principles of stratigraphic correlation, interpretation of terrestrial and marine depositional systems, sequence stratigraphy, event stratigraphy, stratigraphic modeling, and hydrocarbon systems. Laboratory experiments with outcrop sample suites, core and subsurface geophysical data sets. Field trips to describe and interpret local sedimentary rock succession. Prerequisite: Geology 206. Syllabus, Course field trip to Door County.
51-360 - Field Course in Geology, Arbuckle and Ouachita Mountains of Oklahoma, 2 credits, Spring Break. Study of a wide variety of igneous, metamorphic, and sedimentary rock types, stratigraphic and structural features that record the Precambrian and Phanerozoic evolution of the southern margin of the north American continent. Students prepare and present research presentations on a wide variety of topics relating to the geologic history, economic resources, and environmental issues. Field mapping exercises. This is an upper level course open to geology and earth science majors who have completed Geology 205. Consent of instructor. Syllabus, Photos.
51-360- Field Course in Geology, St. Francois and Ozark Mountains of Missouri and southern Illinois, 2 credits, Spring Interim. This course integrates field skills instruction and examples of applied geoscience in the economic and environmental industry (hydrocarbons, mining, groundwater protection) into a synthesis of the geological history revealed in the rock record of Missouri and southern Illinois. Students prepare and present research presentations on a wide variety of topics relating to the geologic history, economic resources, and environmental issues. This is an introductory course, open to geology majors and students interested in geology as a major. Consent of instructor. Syllabus, Photos.
51-360 - Field Course in Geology, Guadalupe, Sacramento and Franklin Mountains of West Texas and New Mexico, 3 credits, Fall Interim or Spring Interim. Students investigate a wide range of geological topics such as: analysis of Paleozoic reef systems, basin analysis and sequence stratigraphy, petroleum geology, igneous and metamorphic geology of the Precambrian basement rocks, textures in Holocene lava flows, cave processes, and modern eolian sedimentation. Field mapping exercises. This is a combined level course. Both beginning geology students and upper level majors are encouraged to apply. Students must have completed at least one course in geology. Consent of instructor.Syllabus, Photos.
51-360 Field Course in Geology, Geological Corridor of the Ordos Basin and Qinling Mountains, North China, 4 credits, Summer Odd Years. This course provides students an opportunity to practice and sharpen their skills in field observations by traversing the geological corridor from Ordos Basin to Qinling Orogen in north-central China. Geological records spanning the Archean to Holocene ages are observed and studied. The fields of sedimentary, igneous, and metamorphic petrology, stratigraphy, tectonics, structural geology, paleontology, paleoclimatology, and mineral resources in diverse geological settings are covered. The history of plate collision of the north and south china plates and consequent impact on lacustrine and fluvial depositional systems of the Ordos basin are explored. A secondary goal of this course is to learn about ancient and modern Chinese history and culture, and to relate and compare them to western culture. This is a combined level course. Both beginning geology students and upper level majors are encouraged to apply. Students must have completed at least one course in geology. Consent of instructor. Syllabus, Photos.
51-360/560 - Field Course in Geology, Evolution of Ancient Seas, Tropical Reefs, and Life in the Nanpanjiang Basin of Guizhou South China, 4 credits, Summer Odd Years. An integrative course that allows students to investigate the full spectrum of carbonate platform and basin facies and to employ advanced techniques of sequence stratigraphy, chronostratigraphy, and basin analysis. Several platform to basin transects highlight lateral variability in platform architecture and provide a basin-wide perspective on carbonate platform and basin evolution. Students evaluate the influences of tectonics, subsidence history, sea level change, and environmental factors on carbonate platform evolution. The history of marine life in the shallow-marine reef ecosystems as well as the causes and effects of the end-Permian mass extinction and subsequent biotic recovery are also examined. A secondary goal of this course is to learn about ancient and modern Chinese history and culture, and to relate and compare them to western culture. This is a combined level course. Both beginning geology students and upper level majors are encouraged to apply. Students must have completed at least one course in geology. Consent of instructor. Syllabus, Photos.
