DIC_ROCK_ALL (3677 rows)
Dictionary table based on the entire version 3 of the BGS Rock Classification Scheme and is populated directly from the 3 supplying tables (BGS.ROCK_NAME_V3, BGS.ROCK_COMPOSITE and BGS.DIC_ROCK_DUMMY). It contains both the base rock names and addditional codes required for specific application, eg. composite names for use on digital geological maps. It is formally approved as the official source of ALL database codes to be used in BGS corporate databases and MUST be followed.

369 CAT  RN  Cataclasite - A type of cataclastic-rock. In the Rock Classification Scheme, it is one in which fragments significantly coarser than the matrix comprise 10 - 50% by volume of the rock. British Geological Survey Research Report RR/99/02, section 7.2 and table 4.  Cataclasite  C  GRBA  24-FEB-00  TMCM  22-FEB-19    R 
370 CATR  RN  Cataclastic-rock - A type of unfoliated mechanically broken rock with primary cohesion. These rocks are formed at higher confining pressures than those without cohesion. The nature of the rocks depends on factors such as confining pressure, original lithology, amount and duration of movement, and the availability of fluids. Cataclastic rocks exhibit grain size reduction by fragmentation of grains during deformation. In the Rock Classification Scheme, they are classified as protocataclasite, cataclasite, and ultracataclasite on the relative proportions of fragments and matrix.
