formation of ore minerals

    Iron Ore: Sedimentary Rock

    The preferred ore minerals of both geochemically abundant and geochemically scarce metals are native metals, sulfides, oxides, hydroxides, or carbonat In a few cases, silicate minerals have to be used as ore minerals because the metals either do not form more desirable minerals or form desirable minerals that rarely occur in large deposits.

    Rock and Mineral Resources

    Ore Genesis The various theories of ore genesis explain how the various types of mineral deposits form within the Earth’s crust Ore genesis theories are dependent on the mineral or commodity Ore genesis theories generally involve three components: source, transport or conduit, and trap.

    How Are Minerals Formed?

    Minerals are found in the earth's crust and mantle, and many were created when feldspar and quartz reacted with other materials during the formation of the planet Igneous rocks come from magma underneath the surface of the earth.

    Veins and Hydrothermal Deposits

    Veins are mineral deposits which form when a preexisting fracture or fissure within a host rock is filled with new mineral material The deposition of minerals is typically performed by circulating aqueous solutions Many ore deposits of economic importance occur in veins Vein deposits are believed.

    Iron Ore ~ Learning Geology

    The iron ore formation started over 18 billion years ago when abundant iron was dissolved in the ocean water which then needed oxygen to make hematite and magnetite The oxygen was provided when the first organism capable of photosynthesis began releasing oxygen into the waters.

    When the heated waters reach cooler rocks at shallower depths, metallic minerals precipitate to form veins or blanket-like ore bodi Another hypothesis suggests that gold-bearing solutions may be expelled from magma as it cools, precipitating ore materials as they move into cooler surrounding rocks.
