Answered by GPT-5 mini AI
Do you mean minerals in geology (natural inorganic solids like quartz or mica) or dietary minerals (nutrients like calcium and iron)? Brief definitions of both:

Geological minerals
- Definition: Naturally occurring, inorganic, crystalline solids with a definite chemical composition (or limited range) and an orderly internal structure.
- Key properties used to identify them: chemical composition, crystal form, hardness (Mohs scale), cleavage/fracture, luster, color, streak, and density.
- Examples: quartz (SiO2), feldspar, calcite (CaCO3), pyrite (FeS2), halite (NaCl).
- How they form: crystallization from magma, precipitation from solutions, metamorphism, or biological processes.
- How they differ from rocks: a rock is an aggregate of one or more minerals (e.g., granite = quartz + feldspar + mica).
- Uses: building materials, metal ores, electronics, ceramics, jewelry, industrial minerals.

Dietary minerals
- Definition: Inorganic elements the body needs to function, obtained from food or water.
- Major (macrominerals): calcium, phosphorus, magnesium, sodium, potassium, chloride — needed in larger amounts.
- Trace minerals (microminerals): iron, zinc, copper, selenium, iodine, manganese — needed in small amounts.
- Roles: bone and tooth structure, enzyme cofactors, fluid balance, nerve and muscle function, oxygen transport.
- Sources: dairy, meat, vegetables, grains, fortified foods, supplements (if needed).

Tell me which type you want more detail about (identification, formation, economic importance, or nutrition and recommended intakes).
