Earth Structures ESCI-451 University of South Dakota Lecture Meetings: MW 1:00-1:50;
F 12:00-1:50 in Akeley-Lawrence Science Center

Catalog Description: Nature and origin of earth structures. Geometric and statistical solutions to structural problems. Introduction to rock mechanics and tectonics. Lab component. Lab fee charged.
Course Overview: This is a course in structural geology and plate tectonics. Structural geology is one of the fundamental sub-disciplines in the earth sciences, and has bearing on many others. Structural geology involves the characterization of deformational features in rocks, and the interpretation of the processes responsible for deformation. The study of structural geology is central to unraveling the past tectonic history of the earth. Structural geology is also important in understanding earthquake risks. The occurrence and form of geologic structures is also important in exploration for geologic resources, including hydrocarbon deposits, ore deposits, and even ground water.
Course Structure: This class meets three times a week, 1-hour meetings on Mondays and Wednesdays, and a 2-hour meeting on Fridays. Mondays and Wednesdays are typically lecture days and Friday is a lab day. Some lectures will be oriented toward preparing students for lab exercises (or even starting into the exercises), and some are on other topics. Lab exercises in the lab manual will often be supplemented with small related exercises on actual geologic maps.
Required Texts: Rowland, S.M., Duebendorfer, E.M., and Schiefelbein, I.M., 2007, Structural Analysis & Synthesis, Blackwell Publishing, ISBN 1-4051-1652-8. Additional readings from Structure textbooks on reserve.
Field Trips: There will be two required field trips for this course. The first will be a one-day field trip to the Sioux Falls area to measure joints in the Sioux Quartzite; this will be scheduled for a weekend day on the first weekend with appropriate weather (high ~50 ºF). The second field trip will be a 2.5-day trip to the Black Hills later in the spring.
Office Hours: Formal office hours are M 9-11, W 2-3, Th 12-2, but please feel free to swing by my office any time, or set up an appointment.
Attendance: Daily attendance is essential. Please communicate with me if you are sick or have another reason for an excused absence. Excused absences are handled differently with respect to late work as outlined below.
Cell Phones: Please turn off your cell phones before entering the classroom.
Grading: There will be a midterm exam and a final exam. There will also be in-class labs and possibly homework assignments. Several quizzes will also be offered. Grading will be based on a conventional scale: A=90-100%; B=80-89.9%; C=70-79.9%; D=60-69.9%; F=<60%. A curve may be applied to some exams at the instructor’s discretion, but don’t count on it. The weighting of coursework will be as follows:
|
Labs/Quizzes |
40% |
| Lab 11 report | 10% |
|
Midterm Exam |
25% |
|
Final Exam |
25% |
Late Work: In this class it is particularly important that work be done on time. Unexcused late work will be penalized 10% per day.

Fine Print:
Cheating: Don’t do it! The university policy on cheating is as follows: “No credit can be given for a dishonest assignment. At the discretion of the instructor, a student caught engaging in any form of academic dishonesty may be: (a) given a zero for that assignment; (b) allowed to rewrite and resubmit the assignment for credit; (c) assigned a reduced grade for the course; (d) dropped from the course; or (e) failed in the course.”
Freedom in Learning: Under Board of Regents and University policy student academic performance may be evaluated solely on an academic basis, not on opinions or conduct in matters unrelated to academic standards. Students should be free to take reasoned exception to the data or views offered in any course of study and to reserve judgment about matters of opinion, but they are responsible for learning the content of any course of study for which they are enrolled. Students who believe that an academic evaluation reflects prejudiced or capricious consideration of student opinions or conduct unrelated to academic standards should contact Associate Dean Kurt Hackemer to initiate a review of the evaluation.
Disabilities: Any student who feels s/he may need academic accommodations or access accommodations based on the impact of a documented disability should contact and register with Disability Services during the first week of class. Disability Services is the official office to assist students through the process of disability verification and coordination of appropriate and reasonable accommodations. Students currently registered with Disability Services must obtain a new accommodation memo each semester.
Course Evaluation: You will have an opportunity to evaluate the course and the instructor using the IDEA Diagnostic Form at the end of the semester.
