"Magnesiocarbonatite - A type of carbonatite. In the Rock Classification Scheme, this term may be used when a chemical classification is necessary because the rock is too fine grained for an accurate mode to be determined, or if the carbonate minerals are complex Ca-Mg-Fe solid solutions. The definition of magnesiocarbonatite is as shown in British Geological Survey Research Report RR/99/06, section 6.1 and figs. 25, 26. See also: dolomite-carbonatite."@en . .
