Given a basic understanding of symmetry operations (Chapter 11) we now examine symmetry using stereographic projections. Two types of symmetry are discussed: point symmetry and space symmetry. Point symmetry relates to mineral shapes (morphology) while space symmetry relates to the atomic arrangement of minerals.
Topics covered in Chapter 12 include:
Stereographic Projections
Point Symmetry Operations
Groups of Point Symmetry Operations
Relating Point Symmetry Operations to Crystal Systems
Naming Point Groups
The 32 Point Groups: Organizing Collections of Point Groups into Crystal Systems
Unit Cells
Bravais Lattices
Naming Planes and Lines in Crystals
Space Symmetry
Space Groups
