BGS Rock Classification Scheme
Calcite-carbonatite - A type of carbonatite. In the Rock Classification Scheme, this term may be used when a modal classification is possible. In a calcite-carbonatite more than 90% of the carbonate is calcite. British Geological Survey Research Report RR/99/06, section 6.1 and fig. 25. See also: calciocarbonatite.

CAVEAT
"Thumbnail" definitions attached to some of the table entries are an interim attempt to provide simple short descriptions of the "unqualified" rock types presented within the BGS Rock Classification Scheme. Every effort has been made to ensure accuracy and consistency but minor contradictions or omissions might be present. The BGS welcomes any feedback pointing out such minor imperfections and/or providing constructive comment and suggestions for improvement of the definitions. In the first instance such feedback should be directed to Dr Tim McCormick.
