    The estimated average concentration of the rare earth elements in the Earth's crust, which ranges from around to parts per million (table 1), exceeds that of many other metals that are mined on an industrial scale, such as copper (55 parts per million) and zinc (70 parts per million).

The Carb Lake Carbonatite Complex is the most northerly located carbonatite in Ontario which has been tested for its mineral content and confirmed to be a carbonatite intrusion. Some aeromagnetic anomalies caused by Geology of the Carb Lake Carbonatite Complex book lying beneath the younger rocks of the Hudson Bay lowlands lying north of Carb Lake could be interpreted as.

The Carb Lake carbonatite complex has been dated by K-Ar isotope methods at ±97 Ma (Sage, ) and intrudes the Oxford-Stull Domain (Stott, ). The Ashram Zone, which is host to the Ashram Rare Earth Element (REE) Deposit, occurs within the Eldor Carbonatite Complex, Québec, Canada.

The complex is located within the Paleoproterozoic New Québec Orogen (Labrador Trough), and has been subjected to greenschist metamorphism and folding during the Hudsonian Orogeny at Ga.

The Prairie Lake complex can also be seen to fall within the North American Mid-Continent gravity high and the major regional Carb Structure which includes several carbonatite complexes and extends for a distance of at least km (see Erdosh,).

Both magnetic and radiometric positive anomalies super. The complex contains a unique, very high grade residual phosphate deposit associated with a well-developed karst topography now buried under glacial lake clays.

During karst development carbonates were dissolved from the carbonatite, and residual minerals, mainly apatite, were concentrated in sink holes and troughs. Carb Lake carbonatite complex, Carb Lake Area, Kenora District, Ontario, Canada: A remote, unexposed carbonatite complex consisting of sovite and silicocarbonatite rocks, delineated by aeromagnetic survey is estimated to cover an area of 8 km².

Some exploratory drilling was done. O’Brien, in Mineral Deposits of Finland, Introduction. Carbonatite is a unique igneous rock type, in that it formed predominantly of carbonate minerals (of which it must contain >50 modal % by definition) along with lesser silicates, phosphate minerals, and oxides.

The term carbonatite was introduced by Brøgger in in his studies of the Fen complex in Norway (Brøgger, Spine title: Carbonatite-alkalic rock complexes, Killala Lake.

The Amba Dongar carbonatite complex has been actively mined for fluorite since The Mt deposit at 30 wt% CaF 2 is hosted in fenite veins and fractures formed by the interaction of carbonatite-derived fluids and surrounding Cretaceous sandstones (Deans et al.,Mariano,Palmer and Williams-Jones, ).
