BGS Rock Classification Scheme

Lime-framestone - A type of limestone, classified on the basis of its biogenic texture. It is a type of reef rock consisting of a rigid framework of colonies, shells or skeletons. Internal cavities are filled with fine sediment. British Geological Survey Research Report RR/99/03, section 3.1, table 3 and fig. 6.

"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.
