Environments of Mineral Formation This chapter explores why groups of minerals frequently coexist. A chemical equilibrium of pressure, temperature, and composition defines the conditions under which rocks form and determines which minerals are present. Quantitative understanding of mineral associations became possible in the 20th century when it became feasible to approximate geological conditions in the laboratory. Phase diagrams are used to determine which minerals form under which conditions.
Topics covered in Chapter 20 include:
• Introduction to Chemical Equilibrium
• Binary Phase Diagrams
• Ternary Phase Diagrams
• Mineral Associations
• A Quick Journey to the Center of the Earth
• The Rock Cycle, Mineralogy-Style
This 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.
