Course Objectives:
1.
Understand weathering processes and the origin of the components of sedimentary rocks.
2.
Describe, identify and classify sediments and sedimentary rocks.
3.
Interpret depositional environments from sedimentary textures and structures.
4.
Interpret and correlate stratigraphic sequences in terms of paleoenvironments
5.
Understand causes and consequences of eustatic and isostatic sea level changes as preserved in the rock record.
Textbook:
Principles of Sedimentology and Stratigraphy, 5th ed., by Sam Boggs (required)
Recommended:
Sedimentary Rocks in the Field, by Stow ($27 on Amazon)
“Rite in the Rain” all-weather field notebook ($8 at ISU bookstore)
Academic expectations:
Learning is the responsibility of each student, and is facilitated by the instructor. Students are accountable for their own
success in this course and are expected to be present and prepared for all class meetings. Students are expected to alert
Pete or Suzy about expected absences as soon as possible. Unexcused absences will result in no credit for labs, exams or
quizzes missed. Assignments turned in late will result in 25% reduction per weekday unless prior arrangements are
made.
Students with disabilities:
If you have a disability and require accommodations, please contact Pete early in the semester so that your learning
needs may be appropriately met. You will need to provide documentation of your disability to the Disability Resources
(DR) office, located on the main floor of the Student Services Building, Room 1010; 515-294-7220.
Grading:
3 exams at 15% each
Labs & report at 45%
10 quizzes at 1% each
