Teaching
History of Earth (Geol 202, Spring 2005)
This course explores major events in the past 4 billion years
of earth history, the interaction of earth systems, and the design
and testing of earth science theories. Some topics covered are:
ice ages and greenhouse atmospheres, continental drift, the nature
of the sedimentary rock record, extinctions and radiations of
flora and fauna, the early evolution of earth, and absolute and
relative dating of rocks. Final grades depend on class and field
trip participation, oral presentations, short papers, computer
labs, and quizzes on the geologic time scale. When you complete
this course, you will be able to:
-
Synthesize observations on different time scales
and from different types of data.
-
Evaluate, compare, and formulate hypotheses
about the causes of major earth history events.
-
Evaluate and compare hypotheses about the linkages
between earth systems and processes in the context of deep time.
-
Design tests of earth science hypotheses based
on collection of new data from the rock record and design of
simple analytical models.
Physical
Geology (Geol 100, Spring 2005)
From earthquakes to landscapes, this course introduces the surficial
and internal processes of the earth. Class lectures address plate
tectonics, minerals, rocks, volcanoes, rivers, glaciers, oceans,
geologic time, and landscape evolution. Labs focus on rock identification
and the rich geologic history of both the Grand Canyon and the
Connecticut Valley. Grades depend on four in-class exams and weekly
lab exercises.
Structural
Geology and Orogenesis (Geol 333, Fall
2007)
This course covers the basic techniques of field geology, structural
analysis, and multidisciplinary approaches to mountain building
(orogenesis). Lectures concentrate on field techniques, stress,
strain, faulting, folding, fabric, rock strength, the relation
between rock deformation and metamorphism, and deformation mechanisms.
Of seven labs, five are field trips that involve collection of
original data. Seven short problem sets emphasize quantitative
skills. During the final weeks of the semester, students research
the Pyrenees of Spain. A final paper and two oral presentations
emphasize fluency in the published literature of structural geology.
Class participation constitutes 10% of the final grade.
Plate Tectonics (Geol 210, Spring 2003)
How fast is London moving away from New York?
Plate tectonic theory gained widespread acceptance in the earth
science community only 30 years ago. The theory explains the origins
of volcanoes and earthquakes, and the locations of mountain belts
and oceans. We will explore topics such as continental drift,
earthquake analysis and prediction, the creation and destruction
of the ocean floor, the Pacific "Rim of Fire," and movement
on the San Andreas Fault. Short in-class presentations, one ten
page research paper, and quantitative homework sets are required.
This course is designed for first- and second-year students who
are comfortable with trigonometry, elementary calculus, vectors,
and high school-level earth science.
Seminar: Appalachian Geology (Geol 341, Fall
2003)
This course is a seminar-in-the-field. Through field trips and
student research projects, we will explore: the assembly and break-up
of the super-continent Pangaea; the igneous, structural, and metamorphic
history of the Northern Appalachian Mountains; the Mesozoic history
of faulting, basin growth, and volcanism in the Connecticut Valley;
the Ice Age and regional glacial landforms and deposits; and the
changing course of the Connecticut River. Evaluation is based
on short papers, oral presentations, and participation in the
3-day-long New England Intercollegiate Geological Conference.
