Question Description
minerals are basic building blocks in geology. Composed of chemical elements bonded together, they in turn are the ingredients for the rocks that compose our planet. Geologists define a mineral very precisely; it must be an inorganic, naturally occurring solid at normal temperatures, with a well-defined chemical composition and an orderly crystalline structure. Despite these rigid requirements, there are actually over 4000 minerals, from common ones like quartz, calcite, halite and hematite to less common examples like joesmithite and pseudo-ixiolite. Some are collected as gemstones, while others have various uses, from industry to cosmetics.
