This is a list of minerals which have Wikipedia articles.. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.
Epidotes are built around the structure [(SiO 4)(Si 2 O 7)] 10− structure; for example, the mineral species epidote has calcium, aluminium, and ferric iron to charge balance: Ca 2 Al 2 (Fe 3+, Al)(SiO 4)(Si 2 O 7)O(OH). The presence of iron as Fe 3+ and Fe 2+ helps buffer oxygen fugacity, which in turn is a significant factor in petrogenesis ...
Use of old mineral names is also discontinued, for example when a name is no longer considered valid. Therefore, a list of recognised mineral species is never complete. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.
Earth materials include minerals, rocks, soil and water. These are the naturally occurring materials found on Earth that constitute the raw materials upon which our global society exists. Earth materials are vital resources that provide the basic components for life, agriculture and industry .

Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present in vast amounts in Earth's crust, and their extraction by humans only occurs where they are concentrated by natural geological processes (such as heat, pressure, organic activity, weathering and other processes) enough to become economically viable to extract.
Iron ore (banded iron formation) Manganese ore – psilomelane (size: 6.7 × 5.8 × 5.1 cm) Lead ore – galena and anglesite (size: 4.8 × 4.0 × 3.0 cm). Ore is natural rock or sediment that contains one or more valuable minerals, typically including metals, concentrated above background levels, and that is economically viable to mine and process.
This information can be valuable in various settings, such as geological surveys and mineral resource assessments. [8] A rare earth element is categorized into sixteen metallic elements. [8] There are over 160 rare earth minerals and only four of these minerals are mined. [9] Most rare earth minerals occur in primary and secondary deposits. [10]
