“When a planet is born from interstellar dust it has about twelve refractory minerals, those resistant to decomposition by heat, pressure, or chemical attack. By the time it is complete with asteroid accretion and finally volcanic activity, about 1,500 different minerals are present. The earth has at least 4,300 species of mineral. This high number is unique in the solar system, a function of biological processes such as photosynthesis that releases oxygen which chemically bonds with almost every element, creating new minerals.” — Craig Childs
