BGS Rock Classification Scheme
Silicate-claystone - A type of silicate-mudstone. In the Rock Classification Scheme, it is a silicate-mudstone consisting of greater than 50% clay-grade particles. The rock is extremely fine-grained with a homogeneous appearance. British Geological Survey Research Report RR/99/03, section 2.3 and table 1.

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.
