READING ASSIGNMENTS MUST BE COMPLETED BEFORE THE CLASS FOR WHICH THEY ARE ASSIGNED!

GRADING:  The course is divided into two units.  The first section deals with igneous rocks, then metamorphic rocks will be covered.  The homework assignments and lecture exams will constitute about 60% of your final grade.  The laboratory grade is worth approximately 40% of the final grade. 
Letter grades and +/- grades will be given.

COURSE DESCRIPTION:

Petrology and Petrography (Geosciences  214) covers the origin, occurrence, and classification of igneous and metamorphic rocks.  The format involves 2 hours of lecture per week, largely devoted to more theoretical aspects of these topics, while laboratory work (6 hours per week) involves hand lens identification and thin section examination of representative igneous and metamorphic rocks.  

Disability Services:  The Office of Disability Services implements the Americans with Disabilities Act (ADA) and insures that UAF students have equal access to the campus and course materials.  This class will work with the Office of Disabilities Services (203 WHIT, 474-7043) to provide reasonable accommodation to students with disabilities.  Make sure to let the instructor know if there are concerns of this type.
