Meeting Time: MW 4:30-7:15 pm
Meeting Place: Room Science C-340
Text: Earth Structure: An Introduction to Structural Geology and Tectonics, by van der Pluijm and Marshak, 2nd Edition 2010, hereafter “PM”
Office Hours: After class, or by appointment, Room C-341
Class Equipment: Each student needs a scientific calculator. The best calculator, by far, is the TI-30XA which costs about $12.
All students also need a ruler, a protractor, a draftsman’s compass, colored pencils, thumbtacks, and 8.5x11 tracing paper
Field Equipment: Rite in the Rain Geological Field Book 540F, backpack, boots or shoes w/ ankle support, water, bug spray, sun screen, + Class Equipment above.
A Map Compass with clear rectangular base and rotating dial. Look in sporting goods stores and Walmart in the camping section.
General Comments In this course we will learn to determine the architecture of rocks observed in the field, and to explain them using a plate tectonic framework.
There will be two Tests, worth 25% each. Quizzes on your homework and labs will be worth a total of 15% of your grade. Weekly field notes from your self-guided field work will be worth 10%. The First Field Trip report will be worth 5%. A report on the Final Field Trip will make up the remaining 20% of your grade. Attendance at both Saturday field trips is required; there are no makeup field trips.
Test Locations: All tests in the normal lecture room.
Attendance Attendance is required. Some portion of each homework and/or lab will be graded. Some of the material discussed in class will not be in the text. Only by coming to class will you be able to get an accurate impression of what will be stressed on the tests and field problems.
Disabilities If you have a disability and need any sort of special accommodations, please see me prior to the first weekly field work.
