Class 2007
Geology 330, Spring 2007. (l–r) Melissa Hage, Steven Jaret, Josh Roberts, Stephanie Nicoll, Tyler Roy, Laura Stair, David Gaines, Meagan Smith

Purpose:
Become familiar with common igneous and metamorphic rocks that comprise the Earth’s crust and interior. Learn how geologists use petrographic observations, geochemical analyses, experiments, and field relationships to understand the origin of crystalline rocks. Class will focus on understanding igneous and metamorphic processes and their relationship to global tectonics.
Skills:
Make and interpret petrographic observations in hand specimen and thin section
Learn the vocabulary used to describe igneous and metamorphic rocks
Use field observations and relationships
Become familiar with experimental methods and geochemical data
