  • Magmatic Segregation - Mining Fundamentals

    Some of the commonly formed mineral deposits formed due to magmatic segregation are iron, granite, aluminum, diamond, chromite, and platinum. The different temperatures and basicity zones that prevail in magma cause the concentration of the ore, thereby resulting in the segregation of various minerals.

  • Ore genesis - Wikipedia

    Magmatic ore deposits are those which are formed during crystallization of a magma, deep underground. The host rock for the mineralization can range from ultramafic to felsic. The deposit can consist of massive ores in some cases, a nd disseminations of rare minerals in others.
