    Carbonatite-Associated Deposits Geology of Canadian

    Carbonatite-associated deposits include a variety of mineral deposits that occur both within and in close spatial association with carbonatites and related alkalic silicate rocks. Carbonatite-associated deposits are mined for rare- earth elements (REEs), niobium, iron, copper, apatite, Vermiculite, and fluorite.

    Carbonatite Wikipedia

    Carbonatite is a type of intrusive or extrusive igneous rock defined by mineralogic composition consisting of greater than 50% carbonate minerals. Carbonatites may be confused with marble and may require geochemical verification. Carbonatites usually occur as small plugs within zoned alkalic intrusive complexes, or as dikes, sills, breccias, and veins. They are almost exclusively associated with

    The Anatomy And Circulation Of Mine Water In Carbonatite

    Ground water occurrence and movement around and in Carbonatite mines, speci˝ cally diamond pipes, are dominated by three types of structures; ˝ rst is the weak zone which allowed the carbonatite to be emplaced; second are the structures that opened when the emplacement occurred and third are the relaxation structures created by mining the ore

    01-02-2018· Alkaline and carbonatite complexes are often associated with high concentrations of economically important minerals, enriched in REE, Nb and phosphate (Wall, 2014, Goodenough et al., 2016). These rocks also host many non-critical resources such as iron, copper, titanium, fluorite, uranium, thorium and vermiculite, some of which have been mined since 770 AD ( Heinrich, 1966,Mariano,

    Geochemistry of Monazite within Carbonatite Related

    The three most important REE minerals in carbonatite related deposits are bastnasite, monazite, and xenotime [ 2 ], and are also the only REE bearing minerals that have been extracted on a commercial scale [ 4 ]. Monazite is similar to bastnasite as a LREE ore mineral, but with slightly more HREE [ 5 ].
