Carbonatites - igneous carbonate-silicate rocks - host the world's major resources for niobium, phosphorous and REE (rare earth elements).Carbonatites represent the least common products of mantle and igneous processes and their emplacement is principally controlled by lithospheric domes and rift structures. Intrusive carbonatites frequently comprise carbonate-amphibole-apatite-pyrocWore assemblages, occur as plugs, cores, dykes, sills sheets, veins, pipes and irregular bodies, are gecichemically anomalous (Ba, Ca, Cl, F, Hf, Mg, Nb, P, REE, S, Sc, SO4, Sri Tb, Ti, D, V, Zr), are associated with alkaline silica-undersaturated igneous rocks forming carbonatite complexes, and display large, intensive alteration haloes. Also carbonatites are similar to limestones, prone to weathering, and may form thick laterite profiles.Magmatic ores (pyrocWore, apatite, bastnaesite, monazite, magnetite, baddeleyite, phlogopite, fluorite, calcite) and weathering related residual and supergene ores (pyrochlore, apatite, magnetite, anatase, vermiculite) are currently being mined on all continents except Australia. Australia is underexplored for carbonatite associated primary magmatic and especially residual-supergene ore deposits. Chances are very high for the finding of new carbonatite, occurrences and associated ores.
