Comprehensive through semester, but with emphasis on second half
Crystallography — crystal systems, angles, axial lengths
Crystal chemistry — Pauling's rules and application
Optical mineralogy — nature of light, modes of interaction with solids, principal
features and origin, relationship to crystallography
 Reflected light — phenomena observed
 Mineral stability — principles
 Mineral stability in different environments (rock-forming settings, tectonic, P-Tredox)
 Mineral occurrence in different rock groups
 Main families of rock-forming minerals and their (very) general structures
 Relationship of key physical properties to structure and composition
 Structural formulas of main rock-forming mineral groups and possible formulas
 Major elements in the Earth and the lithosphere and where they go in minerals
