Part 6: Rock Recipes
Rocks are complicated collections of mineral particles. Four silicate mineral groups make up 90% of the crustal rocks: mafic minerals, quartzes, feldspars, and micas. Rocks come in three basic varieties: ingenous, sedimentary, and metamophic. These are the ingredients of the rock cycle.
