BGS Rock Classification Scheme

Metasedimentary rock composed largely of calcsilicate and/or carbonate minerals - A class within metasedimentary rock based on modal composition. In the Rock Classification Scheme, these are metamorphic rocks containing more than 50% calcsilicate and/or carbonate minerals. This class includes calcsilicate-rock, and metacarbonate-rock. British Geological Survey Research Report RR/99/02, section 3.2 and figs. 6, 7.

"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.
