This chapter is an introduction to the science of crystallography, which is a symbolic language for describing repeating patterns in 2-D, 3-D, or any dimension of space one wants. The crystal structures of minerals are repeating patterns in 3-D, and we can take advantage of all the work that has been done to study patterns to help us understand minerals. Representations of the six crystal systems are animated to help visualize the orientations of the three crystallographic axes. The relationships between the spherical and stereographic projections are also shown.
Topics covered in Chapter 4 include:
• Two-Dimensional Space
• Symmetry Operations
• Three-Dimensional Space
• Isometric System
• Tetragonal System
• Orthorhombic System
• Hexagonal System
• Monoclinic System
• Triclinic System

The Mineralogy and Optical Mineralogy Series is specifically designed to take full advantage of digital media technology to empower students and teachers of mineralogy. Using color photographs, illustrations, movies, 3D models that can be rotated, interactive diagrams, and review questions, this series makes a challenging subject approachable. Also, each chapter in the series is available separately allowing the reader to pick and choose only those chapters they need for their specific course.
