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.

| 2816 | PYRBRC | RN | Pyroclastic-breccia - A type of pyroclastic-rock. In the Rock Classification Scheme, it is a pyroclastic-rock in which more than 75% of the pyroclastic fragments exceed 64 mm in size. Agglomerate and pyroclastic-breccia are separated according to the relative proportion of blocks (angular fragments exceeding 64 mm) and bombs (rounded fragments exceeding 64 mm): if blocks dominate over bombs the rock is pyroclastic-breccia. It is the consolidated equivalent of block-tephra or bomb-block-tephra.
