A. Introductory Courses and Courses for Non-concentrators

G.S. 100-115 are short (half-term) courses. They consist of detailed examinations of restricted geologic topics. The department lists the specific courses from this series in the Time Schedule for the terms they are offered (fall and winter terms only). Each course, when offered, meets twice weekly for half of the term (first half or second half), and the specific dates for each course are printed in the Time Schedule. These courses are designed primarily for students with no prior geologic training and they are open to all interested persons. G.S. 100-115 are offered on the graded pattern (optional pass/fail).

112. Geological History of Michigan. (1). (NS).

Michigan has not always been a land of upland temperate forests surrounded by the Great Lakes. During major intervals of time, what is now Michigan lay under broad tropical seas or was beset by extensive volcanism. At other times, vast ice sheets a mile thick sculpted the surface of Michigan. Remains of animal and plant life from these times are distinctly different from those of the present day. This course presents an introduction to the evidence from which this changing geological panorama has been inferred. Topics to be considered include the nature of the Precambrian world and its life; Early Paleozoic coral reefs and associated salt deposits; Late Paleozoic coal swamps; major hydrocarbon deposits in Michigan; glacial geology of the recent past, the geologic development and history of the Great Lakes; and the rise and fall of the diverse Pleistocene megafauna of mammoths and mastodons. There will be an opportunity to examine some excellent fossil specimens in the collection of the Museum of Paleontology, and oil well cores from the Subsurface Laboratory. Grades will be based on a final examination. [Cost:1] [WL:4] (Budai)
