What is a mineral? • “A naturally occurring, inorganic solid that possesses an orderly crystalline structure and a definite chemical composition” 1. Naturally occurring—NOT man made • Synthetic materials (such as cubic zirconia) don’t count 2. Inorganic—plant and animal products don’t count • For example, coal is NOT a mineral Read more…
