Courses in Geological Sciences (Division 377)

A. Introductory Courses and Courses for Non-concentrators

G.S. 100 114 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. 100-114 are offered on the graded pattern (optional pass/fail).

100. Coral Reefs. (1). (NS).

Coral Reefs will be an in-depth tour of the biological and physical processes active in modern reef systems to provide a detailed understanding of the ecology of the individual organisms and the complex nature of their interactions within the reef community. Evolution of the reef community will be examined, ranging from the crude framework structures formed over one billion years ago by primitive algae to the luxuriant and diversified reefs of the modern-day oceans, to define the evolutionary strategies of reef building organisms. By tracking these evolutionary strategies through geologic time, the implications of man's intervention with the Earth's hydrosphere and atmosphere on the character of future reef communities will be considered. (Lohmann)

102. Energy from the Earth. (1). (NS).

A survey of the principal non-nuclear energy resources of the earth: oil (petroleum), natural gas, coal, tar sands, oil shale. Includes discussions of the geology of these materials, their composition and/or mineralogy, types of deposits, recovery, utilization and technology, and ecological problems. No prerequisites, except that a course in elementary chemistry (high-school or university) is highly desirable. Lectures only profusely illustrated with slides. Grade based solely on final examination. Text: Buedisili & Firebaugh (Eds.), Perspectives on Energy (3rd ed.) published by Oxford University Press, 1982. (Wilson)

103. Dinosaurs and Other Failures. (1). (NS).

This course will provide an introduction to our current understanding of dinosaurs and certain other reptilian groups of the Mesozoic Era. It is intended for students with an interest in geology, paleontology, or evolution, but does not require prior training in these fields. The course will deal with broad features of the evolutionary history of dinosaurs, methods of reconstructing dinosaur behavior and ecology, new developments in our interpretation of the biology of dinosaurs, and possible causes for the extinction of dinosaurs. There will be two lectures each week and a single exam at the end of the course. (Fisher)

104. Ice Ages, Past and Future. (1). (NS).

This course looks at the effects of past glaciations on the landscape and on life, man in particular. Concurrent climatic and paleogeographic changes, both in continental and oceanic realms, are also reviewed. The causes of the ice ages that have dominated the Earth for the past two million years and predictions of future ice ages based on current geological research are examined. The course consists of lectures and one (final) exam. (Farrand)

105. Continents Adrift. (1). (NS).

The seemingly stable land masses of the world are actually in motion. Continental collisions and fragmentation, formation of new ocean floor, and specific patterns of earthquakes and volcanoes are some of the events caused by earth motions. This course presents the modern view of plate tectonics and continental drift, their suspected causes, and the predictable consequences of such a dynamic system. (Bogen)

107. Volcanoes and Earthquakes. (1). (NS).

The course is a study of the earth in action and includes the following topics: geography of earthquakes and volcanoes; catastrophic events in historic times; size and frequency of occurrence of earthquakes and volcanic eruptions; the products of volcanism; volcanic rocks; volcanic activity through geologic time; volcanic exhalations and the evolution of the earth's atmosphere and oceans; relationship of earthquakes and volcanoes to plate tectonics and the internal dynamics of the earth; volcanism on other planets; volcanism and geothermal energy; manmade earthquakes; and earthquake prediction and control. Instruction by lecture, evaluation on basis of final exam. (Pollack)

108. Minerals in the Modern World. (1). (NS).

Lectures provide insights into the character, distribution, utilization, economics, politics, and deleterious side effects of mineral resources. The geology, including how a resource occurs, how it originates, and how much exists receive the most emphasis. The course centers around metals, such as iron, aluminum, and copper, essential to modern industrial society, fertilizers, and water, rather than energy, which is covered in Geological Sciences 102. Current events related to minerals and national or international affairs are always incorporated as they arise. Grading will be based on one half hour exam and a one hour final. Texts: Kesler, Our Finite Material Resources, McGraw-Hill, 1976; G.S. Course Pack, Dollar Bill Copying. (Cloke)

112. Nuclear and Other Future Energy Resources. (1). (NS).

A survey of the geology, mineralogy, present and future developments, and ecological implications of nuclear energy, fusion, tar sands, and oil shales. (Cloke)

117. Introduction to Geology. Credit is not granted for G.S. 117 to those with credit for an introductory course in geology. (5). (NS).

This course provides a one term, introductory level survey of the field of geology. No previous science background is assumed. The general themes of Geology 117 are the evolution of the earth, and life on earth, and the processes responsible for the observed changes. Emphasis is on historical geology, but physical geology is introduced briefly early in the course. The course provides the essential educational background for a greater appreciation of the geological world. There are three lectures and one discussion session each week and an auto tutorial laboratory. The laboratory is open about 25 hours per week, and students may come in at any time it is open. Approximately three to four hours each week are required to complete the laboratory work. Course evaluation is based on two lecture examinations, discussion section quizzes on reading assignments, a final examination, and several short laboratory quizzes, and graded assignments. This course may be elected, without the laboratory, as Geological Sciences 119. (Dorr)

119. Introductory Geology Lectures. Credit is not granted for G.S. 119 to those with credit for an introductory course in geology. (4). (NS).

This course consists of Geology 117 without the laboratory. There are three lectures and one discussion per week. Course evaluation is based upon two lecture examinations, a final examination, and short weekly quizzes in discussion sections. See Geology 117 for the description. (Dorr)

121(111). Physical Geology. Credit is not granted for G.S. 121 to those with credit for an introductory course in geology. (4). (NS).

This course emphasizes the physical and chemical processes that affect the earth. It first considers the minerals and rocks which make up the planet and the many processes which break them down and through erosion, transportation, and deposition both continually change the earth's surface and create new rocks. Then the major processes that act internally to form mountain chains and new ocean basins and to move the relatively few large plates which comprise the earth's surface are brought together through the hypothesis of plate tectonics. The course ends with a short survey of the mineral and energy resources of the earth. The format consists of three illustrated lectures, a three-hour laboratory session utilizing exercises designed to supplement the information from the lectures and text, and a one-hour discussion section each week. An optional field trip is held in the middle of the term. Evaluation is based on class examinations and laboratory performance. The course presumes no prior knowledge of the geological sciences. (Farrand)

122. Introduction to Physical Geology. Credit is not granted for G.S. 122 to those with credit for an introductory course in geology. (3). (NS).

This course consists of the three weekly lectures associated with Geology 121 plus a one-hour discussion each week designed to help the student integrate and clarify the material covered in the lectures and text. See the Geology 121 description for further details about the material covered. There will be one optional field trip about midway through the course. Evaluation of the student will be primarily based on the individual's exam grades and participation in the discussion section. The course presumes no prior knowledge of the geological sciences. (Farrand)

201/Geography 201. Introductory Geography: Water, Climate, and Man. (4). (NS).

This course is a basic introduction to the field of physical geography and emphasizes various topics including maps, seasons, time, the atmosphere, radiation and heat balance, circulation, moisture and precipitation, air masses (fronts), and water supply. Students also study ground and surface water, climate classification, hot climates, transitional climates, cold climates, permafrost and changes in climate (glaciers). Students in this lecture-laboratory course are evaluated by midterm and final examinations with satisfactory completion of the laboratory work a prerequisite to this final course evaluation. The text is Strahler, Introduction to Physical Geography while the laboratory workbook is Strahler, Exercises in Physical Geography. (Outcalt)

281/Environ. Studies 350. Environmental Geology. (4). (NS).

Because of the absence of course prerequisites, an effort is made to introduce essential geologic material either through lectures or text readings or both before the course moves on to a consideration of environmental concerns. A special effort is made to limit the coverage of geology to those elements which are of particular significance in a discussion of man's physical environment. Since the general course emphasis is on environmental geologic topics, discussion of other environmental issues is generally avoided unless these issues are at least peripherally related to geology. Course topics include rocks and minerals of economic importance; surface and ground water; the origin, distribution, and nature of soils; metallic and nonmetallic ore deposits; the environmental aspects of the action of streams, winds, rivers, glaciers, and shoreline processes; mass movement such as landslides and similar processes; and construction problems involving geological subjects. Although questions are encouraged, the course is not intended to provide an opportunity for extensive, seminar-type discussion. Attendance and participation in lectures and examinations are required. There are three hours of lecture each week. One term exam and a final examination are required. The examinations are noncumulative. The text is Keller's Environmental Geology. The discussion sections meet for one hour each week, but an additional hour of work each week may be required during the latter half of the term. The discussion sections are devoted to group project work leading to a final oral presentation focusing on geologic environmental problems of towns and adjacent areas in the vicinity of Ann Arbor. This course cannot be used as part of a concentration plan in geology and mineralogy. (Dorr)

282/Environ. Studies 349. Environmental Geology. (3). (NS).

This course consists of the lecture portion only of Geology 281/Environmental Studies 350. (See description for Geology 281.) Students who elect this course do not complete the group project study of the environmental geology of an area. Lecture, reading, and examinations are the same. (Dorr)

417/A&OS 417. Geology of the Great Lakes. Permission of instructor. (2). (Excl).

This is a course that presents the general physical science and geology of the world's largest freshwater system, the North American Great Lakes. Topics to be covered include introductions to lake circulation and sedimentology, the relevant aspects of the North American glaciations, the sediments and geologic history of each lake, and a section on the various research efforts now being conducted on various Great Lakes topics, including pollution. This course is intended for those persons, especially aquatic scientists, with only a limited background in geology (introductory physical geology or permission of instructor) but who are interested in learning about the physical and chemical aspects of natural freshwater systems. Evaluation will be based upon a midterm and final exam and a short term paper. (Rea)

231. Elements of Mineralogy. Prior or concurrent enrollment in the first term of elementary inorganic chemistry. (4). (NS).

This course is a comprehensive introduction to the nature, properties, structures, and modes of occurrence of minerals. The first three-fourths of the course (three lectures per week) considers the general features of minerals and includes topics such as introductory crystallography, crystal chemistry, and introductory phase equilibria. During the last portion of the course, the principal rock-forming minerals such as feldspars, proxenes, and olivines are individually reviewed with respect to properties, structures, genesis, and other characteristics. The laboratory (one three-hour laboratory each week) is divided into three sections: (1) three weeks of morphological crystallography plus x-ray diffraction, (2) six weeks of systematic mineralogy during which students become familiar with the properties and associations of approximately seventy-five significant minerals, and (3) four weeks of introduction to the use of the polarizing microscope as applied to both crushed mineral fragments and rock thin sections. There is one required field trip. Optical mineralogy is covered in a separate recitation. Geology 231 is a prerequisite to the professional concentration program in the Dept of Geological Sciences. (Peacor)

305. Sedimentary Geology. An introductory geological sciences laboratory course; or permission of the instructor. (4). (NS).

Geological Sciences 305 is one of several geology core courses, required of all concentrators in the Department of Geological Sciences. The rigorous course format consists of three lectures and one scheduled two-hour laboratory session each week, in addition to 4-6 hours of evening laboratory work each week that can be carried out individually at the student's own pace. In addition, four one-day field trips are required, and are scheduled from September to November during the Fall Term. The laboratory portion of the course material consists of in-depth familiarization with terrigenous clastic and non-clastic rocks, both in hand-sample and in thin-section, their fabrics, compositions, and classifications. The lecture portion of the course deals with the principles and processes of sedimentation, a survey of modern sedimentary environments, diagenesis of sedimentary rocks, and the general tectono-sedimentological evolution of the phanerozoic North American continent. Evaluation of students is based on three lecture exams, a final exam, laboratory quizzes and assignments, and field trip projects. Sedimentary Geology is intended only for the serious student of the earth sciences. (Wilkinson)

415. Introductory Economic Geology (Metals). G.S. 310, 351, or permission of instructor. (4). (Excl).

This is a survey economic geology course whose main emphasis is on gaining an understanding of how we study and describe ore deposits as well as studying specific examples of each major type. Fossil fuels and most non-metallic ore deposits are left to other courses in the department. Such a study of the processes, controls on and extent of different kinds of ore deposits will allow the student to better understand the problems in locating concentrations of natural resources as well as the technical, practical, environmental and monetary considerations that decide whether or not an elemental concentration is an ore. The course is directed toward the senior/first-year graduate student who has completed the core courses in geology and as such is an elective outside the required departmental sequence. The method of teaching will combine lecture and discussion with a one hour per week lab session which will be devoted to problem solving the first half of the term and small lab exercises the second half. There will be a midterm and final as well as a term paper on a subject of the students' choosing. No text books are required but Ore Petrology by Stanton is recommended. (Kelly)

418. Paleontology. G.S. 117 (or the equivalent), or Biol. 105 or 114. (3). (Excl).

This course is an introduction to the principles, methods of analysis, and major controversies within paleontology. It will familiarize the student with the fossil record (primarily, but not exclusively, of invertebrates) and its use in dealing with problems in evolutionary biology, paleoecology, and general earth history. Three lectures weekly and one field trip; midterm, final examination, and term paper. Required text: Raup and Stanley, Principles of Paleontology (2nd edition).

419. Paleontology Laboratory. Prior or concurrent enrollment in G.S. 418. (1). (Excl).

This course is an introductory laboratory in paleontology. It will involve observation, analysis, and interpretation of fossil specimens (primarily invertebrates) and relevant material of living organisms. Its goal is to give the student experience in dealing with paleontological problems and to develop a familiarity with the systematics and morphology of important groups of fossil organisms. Students should be registered concurrently or previously in Geological Sciences 418. One three-hour lab weekly; lab quizzes, exercises, midterm, and final examination. Required text: Moore, Lalicker, and Fischer, Invertebrate Fossils.

420. Introductory Earth Physics. Math. 116. (3). (Excl).

An introduction to the physics of the solid earth. Topics included are: seismology and structure of the earth's interior; geodynamics; gravity and the figure of the earth; isostasy; geomagnetism and paleomagnetism and its implications for plate tectonics; geothermics and the thermal history of the earth. Instruction by lecture; student evaluation on the basis of weekly problem sets and two hour exams. (Ruff)

437. Evolution of Vertebrates. A course in general biology or historical geology. (4). (NS).

The course will cover the fossil evidence of the evolutionary history of the vertebrates. Lectures will describe the diversification, adaptation, and paleoecology of fishes, amphibians, reptiles, and birds from the Cambrian to the recent. Laboratories, one three hour session per week, will be devoted to the study and identification of fossils and characteristics of the vertebrate groups. The grading system will be based on two exams and a term paper. (Smith)

448. Pleistocene Geology. An introductory geological sciences laboratory course or permission of instructor. (4). (NS).

This course begins with the study of glaciers, their origin and mechanics of movement, as a background to investigation of the depositional and erosional effects of glaciers on the landscape, with Michigan as a prime example. Moraines and outwash landforms and the sediments that compose them are studied in some detail. Glacial-lake shorelines and deposits and the history of the Great Lakes around Michigan are also given much emphasis. Next, phenomena characteristic of periglacial regions such as permafrost, loess and river systems are discussed, and then broad-scale phenomena such as fluctuations of sea level during glaciations and wet periods ("pluvials") in now dry parts of the Earth are reviewed. Finally the still enigmatic causes of ice ages are considered. Geology 448 is intended for students who will utilize its subject matter in their professional activities, primarily in geology, archaeology, life sciences, engineering and natural resources. It is an intensive course requiring at least one introductory course in physical geology as background including the basic skills of rock identification and topographic map reading. The first half of the course is strongly field oriented; there are three or four required field trips, including one weekend trip. The course format includes three lectures per week and several exercises to be done outside of class. In addition to the text there are a number of other readings, as well as a term paper relating Pleistocene geology to the student's field of specialization. (Farrand)

467. Stratigraphy. G.S. 305, 310, and 351. (3). (NS).

This is a course in advanced historical geology and paleotectonics. The structural and stratigraphic evolution of Western Europe, North Africa, Middle East, and North America is discussed in lectures. The approach is stratigraphic. Within the historical framework, specific rock sequences are examined. In the course of this the student should become familiar with many of the classic stratigraphic sections of North America and Europe. These include sheet quartz arenites, geosynclinal clastics and euxinic siliceous sediments of basins, paralic sediments, red beds, black shales, sheets of shelf carbonates, cyclic sedimentation, starved basins and shelf marginal carbonates, various types of reefs and carbonate buildups, and evaporites. Background needed: a course in historical geology or regional stratigraphy and a course in petrography (preferably sedimentary petrography, and structural geology). (Wilson)

478/A&OS 478. Chemical Oceanography. Chem. 365 or the equivalent. (3). (Excl).

This course will review present knowledge concerning the chemistry of the oceans, identify the areas where this knowledge is limited, and examine conditions and processes that have a significant bearing on the ocean and man's activities. The course begins with a brief synopsis of the chemical composition of seawater. This is followed by a discussion of the physical factors and chemical principles which govern the system and therefore form the theoretical framework of marine chemistry. Finally, important aspects of marine chemistry are examined in detail. These include dissolved gases, carbon dioxide/carbonate equilibria, nutrient cycling, organic materials, primary and secondary productivity, sediments and sedimentary processes, and geochemical models of the oceans. Selected topics of general interest such as marine pollution and chemical resources are also discussed. The interaction of the atmosphere, the biosphere, and sediments with the hydrosphere is stressed throughout the course. Course requirements include a midterm, the final examination and a term paper. Study guides consisting of problems and discussion questions are issued for each major topic in the course. Text: Broecker and Peng, Tracers in the Sea. (Meyers)
