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.

638 DLMSPT  RN  Dolomite-microsparstone - A type of dolostone, classified on the basis of its diagenetic texture. It is similar to dolomite-sparstone but with 4 - 32 µm crystal size. Crystals are resolvable under an optical microscope.

645 DLPSPT  RN  Dolomite-pseudosparstone - A type of dolostone, classified on the basis of its diagenetic texture. It is a dolostone composed almost totally of a divergent radial fibrous calcite cement in which grains or in-situ biogenic material do not constitute a framework.

655 DMTN  RN  Diamicton - A type of siliciclastic sediment and sedimentary rock. Sediments that are poorly sorted and contain a wide range of clast sizes can be given this root name. The strict descriptive definition relates to range of particle size and not to relative abundance of any or all size classes. These sediment types therefore traverse the boundary of siliciclastic rudaceous, arenaceous and argillaceous sediments. This is the unconsolidated equivalent of diamictite.
