Courses in Geological Sciences (Division 377)

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).

101. Waves and Beaches. No credit granted to those who have completed or are enrolled in GS 276. (1). (NS). (BS).

This short course approaches the subject of "waves and beaches" by combining relevant topics in both oceanography and geology, although no previous background in these subjects is required. We shall attempt to understand this dynamic place where land and sea interact by emphasizing the processes responsible for the major types of coastlines and the geologic/oceanographic phenomena associated with them. Some of the topics which will be considered include: fundamentals of wave and tide theory; the impact of waves and tides upon beaches; coastal geology; coastal processes on a short- and long-term time scale; estuaries; and, the impact of plate tectonics upon coasts. Instruction will be by lecture. Grades will be based on one exam which shall be given at the end of the course. Cost:1 WL:1 (Wilkinson)

103. Dinosaurs and Other Failures. No credit granted to those who have completed or are enrolled in GS 273. (1). (NS). (BS).

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. Cost:1 WL:3 or 4 (Cox)

111. Climate and Mankind. No credit granted to those who have completed or are enrolled in GS 201 or 275. (1). (NS). (BS).

The intent of GS 111 is to give a heightened awareness to students of the nature and fragility of the Earth's climate, and how changes in climate have affected past civilizations and may affect our future. Course topics will include: a description of the climate systems of the Earth, the atmosphere, oceans and polar ice caps; the information we gather to understand the history of those systems; how changes in climate have affected past civilizations, and what may happen to the planet if the predicted "Greenhouse Effect - Global Warming" finally arrives. Cost:1 WL:4 (O'Neil)

113. Planets and Moons. No credit granted to those who have completed or are enrolled in GS 204 or 278. (1). (NS). (BS).

This lecture course provides a current survey of the geology and climates of the various bodies of the solar system in light of the extraordinary advances in planetary exploration during the past two decades. Topics treated include historical development of geological ideas about the solar system, planetary evolution, variability of geological processes throughout the solar system, and individual portraits of the principal members of the solar system family. No previous geological background is required. Course grade will be determined from a single objective-type final examination. Cost:2 WL:4 (Van Keken)

115. Geologic Time. No credit granted to those who have completed or are enrolled in GS 135. (1). (NS). (BS).

Until the middle of the 18th century the Earth was generally thought to be less than 10,000 years old, and according to many, close to its apocolyptic end. We now know that the Earth formed 4.5 billion years ago and that the entire history of mankind is nothing but the latest tiny fraction of Earth history. The formation of rocks, continental drift, volcanoes and earthquakes is evaluated in the framework of geologic time and plate tectonics. The discovery of time from the Renaissance to the latest high tech developments in radioactive dating is reviewed. Finally, the history of planet Earth will be described including its accretion out of dust and giant impacts, the origin of the Moon, the formation of the atmosphere and oceans, the development of life and the building of continents. The course will draw upon examples meaningful to the student to illustrate the principles. Lectures twice weekly for half the term. Course pack provides most of the diagrams. A final one hour examination. Cost:1 WL:3/4 (Mukasa)

117. Introduction to Geology. No credit granted to those who have completed or are enrolled in GS 116, 119, or 120. Those with credit for GS 205 may only elect GS 117 for 4 credits. (5). (NS). (BS).

This course involves a one-hour lecture followed by a two-hour hands-on 'practicum.' It is intended for students interested in environmental issues, in particular the relationship between earth sciences and short-term (on the order of years) human concerns. We will examine a wide range of environmental issues, such as earthquake risks, volcanic hazards, slope stability and mass movement, minerals, fossil fuels (petroleum, natural gas and coal), surface and groundwater pollution, solid toxic and radioactive waste disposal. The class is aimed at all who are interested in everyday environmental concerns and want to have an introductory, hands-on approach to understanding and solving these problems. It is intended for non-science students and there are no prerequisites, except for an interest in the near future of our planet. Because you will get a solid understanding of major environmental issues, the class can serve as a pre-concentration requirement in environmental geology.

The order of major subjects is (1) fluids and their properties, (2) crystal structural and crystal chemical properties of crystalline solid phases, (3) general chemical relationships among phases, (4) systematics of significant mineral groups, especially clay minerals, and (5) minerals and processes among minerals in weathering, diagenetic, sedimentary, igneous, and metamorphic systems. There is a laboratory in which students learn the characteristics and properties of the principal mineral and rock systems. There are two hour exams, a final exam, and occasional quizzes. (Peacor)

266. From Stars to Stones. High school math and science. Those with credit for GS 114 may only elect GS 266 for 2 credits. (3). (NS). (BS).
From Stars to Stones
starts from stellar evolution and the formation of the elements in stars, and ends at the formation of terrestrial planets (especially our Earth) from these elements and the early evolution of these planets. Students will learn cosmochemical and geochemical concepts and methods, and apply them to study several theme topics. The theme topics may include: origin of the elements, lifetime of the sun, abundance of the elements, age of the Earth and solar system, origin of the Earth, internal structure of the Earth, planetary atmospheres, and meteorites. Though factual knowledge is an important part of the course, emphasis is on how scientists study and solve problems and how science progresses using historical examples. (Quantitative reasoning will be an important part of the course.) (Zhang)

269. Evolution of the Earth. No credit granted to those who have completed or are enrolled in GS 135. Those with credit for GS 115 may only elect GS 269 for 2 credits. (3). (NS). (BS).

This seminar course is intended for first and second year students with no previous knowledge of, or experience in, the earth sciences. The material will introduce students to the history of the earth from its formation in the solar nebula, through the development of the continents, oceans, atmosphere and life to its present state as an active planet. The course will explain how various features of the earth "work," including continental drift, volcanoes, and the formation of most rocks, how theories are developed in geology and how the magnitude of time has been determined. The course will be divided into two halves. In the first half the basic concepts will be explained. In the second half students will each make a presentation covering a relevant subject which will be followed by discussion. Assessment will be by two one-hour examinations and an oral presentation that will form the basis for a term paper. Course pack. (Halliday)

270. Plate Tectonics. No credit granted to those who have completed three of GS 105, 107 and 205. Those with credit for one of GS 105 and 107 may only elect GS 270 for two credits. Those with credit for GS 205, or both GS 105 and 107, may only elect GS 270 for one credit. (3). (NS). (BS).

The theory of plate tectonics, called dogma by some and paradigm by others, describes the mobility of continental and oceanic domains of the Earth's crust, as they are in constant motion along plate boundaries with respect to each other. The theory explains earthquakes and volcanoes, the topography of the Earth and the faunal and floral diversity of its living and fossil inhabitants. Lectures about the evidence also explore alternative explanations. The course involves three hours of weekly meeting time, a textbook and selected reading material. No background in Earth science is necessary. Evaluation is based on two exams, a series of student presentations on selected topics and written essays on the same subject. Cost:1 WL:4 (Van der Voo)

271. Natural Hazards. Those with credit for GS 107 or 205 may only elect GS 271 for 2 credits. Those who have credit for both GS 107 and 205 may only elect 271 for 1 credit. (3). (NS). (BS).

This freshman/sophomore seminar examines various types of natural hazard such as earthquakes, volcanoes, hurricanes and tornadoes. We make case studies, explore geological and geophysical background, and discuss the social aspects of natural hazards. Each student is given a project, which will be presented in a class and reported as an essay. Evaluation is based on an exam, the presentation and essay. No science background is required, but active participation of students is expected. Cost:1 WL:4 (Lange)

275. The Ice Ages: Past and Present. Those with credit for GS 104 may only elect GS 275 for 2 credits. (3). (NS). (BS).

Characteristics of the Earth's climate system and how various components of that system operate to produce times when extensive ice sheets covered large parts of the Earth's surface. The role in climate change of the oceans, the atmosphere, the ice sheets themselves, orbital variations, and the movement of the continental and ocean boundaries are presented and discussed. Cost:1 WL:1 (Moore)

277/Environ. Stud. 361. Humans and the Natural World. Those with credit for GS 123 may only elect GS 277 for 1 credit. (3). (NS). (BS).

278. Earthlike Planets. High school science and math recommended. Those with credit for GS 113 may only elect GS 278 for 2 credits. (3). (NS). (BS).

In a small class room setting, Earthlike Planets introduces the undergraduate to the terrestrial planets: Mercury, Venus, Earth, moon, and Mars. Studies of solid planets will be used as a vehicle to better understand our own world and the methodology and limitations of science in the presence of conflicting hypotheses and ambiguous data. Since western society has made a significant commitment of resources toward the exploration of the planets, we must consider not only the scientific merits of the endeavor but also its historical origins. Grades will be based upon class participation, a midterm exam, and a final project. The final project will provide the basis for a written report and an in-class oral presentation. Cost:2 WL:4 (Van Keken)
