  • How did minerals form in our earth? - UCSB Science Line

    The process of mineral formation during the cooling of magmas and lavas is the most important process of mineral formation on the Earth. Finally, some minerals are formed by a very complicated combination of changes in pressure and temperature. Some chemicals are very sensitive to even small changes in temperature and pressure.

    A rock is composed of one or several minerals. Metals are present in most rocks, but far from all rocks are considered valuable enough to mine. Rocks may contain mineralisations, which is the occurrence of valuable minerals in a large quantity. Mineralisations or mineral deposits are formed by many complex geological processes.
