Learning Goals
Students should be able to:
- Describe the modal mineralogy and texture of a rock.
- Classify (assign complete names to) rocks, using published schemes employed by professionals.
- Use fundamental petrographic observations to identify minerals and rock textures in thin section.
- Describe rock-forming processes.
- Evaluate the petrogenesis of rocks and rock associations in a plate tectonic context.
- Assess or evaluate how petrology transfers to other fields of study.
