  • Nickel mining in New Caledonia Wikipedia

    Nickel mining in New Caledonia is a major sector of the New Caledonian economy. The islands contain about 7,100,000 tonnes of nickel which is about 10% of the world's nickel reserves [citation needed].With the annual production of about 107,000 tonnes in 2009, New Caledonia was the world's fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000).

  • Laterite Wikipedia

    Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which produces

  • Photos of rocks and minerals

    The rock is of Ordovician age. Turbidity sequence is typically composed of many alternating layers of siltstone (very fine sandstone) and mud. Silt settles faster than clay minerals do and therefore every current is composed of two distinct layers (there may be even more). These samples are from a turbidity current from Spain.

  • Rock (geology) Wikipedia

    A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks, metamorphic rocks and sedimentary rocks.Rocks form the Earth's outer solid layer, the crust.

  • Ultramafic rock Wikipedia

    Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). The Earth's mantle is composed of ultramafic rocks.

    Rocks and minerals. The most widespread rock is the harzburgite, a rock consisting in olivine and pyroxen (bronzite) the later often in large cristals.Harzburgite is the major rock forming the ultrabasic massifs of New Caledonia.Dunite is another important rock consisting almost entirely in olivine. Serpentines, or more correctly serpentinites, are hydrated.

  • Laterite Sedimentary Rocks

    Iron-rich variety consists of hematite and goethite. These minerals give reddish color to the soil/rock and sometimes such deposits are mined for their iron and nickel content (in Cuba and New Caledonia). Aluminous laterite (bauxite) is mostly composed of aluminum hydroxides gibbsite, diaspore, and boehmite. Not all bauxites are laterites, though.
