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.

| 262 | BGCCOL | RN | Boghead-cannel-coal - A type of sapropelic-coal. It is a transitional stage between cannel-coal and boghead-coal in which miospores dominate over alginite. British Geological Survey Research Report RR/99/03, section 6.2 and fig. 10. | Boghead-cannel-coal | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |
| 263 | BGCOL | RN | Boghead-coal - A type of sapropelic-coal. It is similar to cannel-coal but browner and rich in alginite with very few miospores. It appears unstratified on macroscopic examination. Microscopic examination shows that boghead-coal consists of alginite and very finely dispersed inertinite and vitrinite. The proportion of alginite can vary widely. Boghead-coal is sometimes referred to as torbanite. This term is not recommended for usage.

| 269 | BIOR | RN | Biological rock - A type of biological deposit. In the Rock Classification Scheme, it is the consolidated equivalent of biological sediment. | Biological rock | C | GRBA | 24-FEB-00 | TMCM | 13-MAR-19 | A | |
| 270 | BIOSD | RN | Biological sediment - A type of biological deposit. In the Rock Classification Scheme, it is the unconsolidated equivalent of biological rock. | Biological sediment | C | GRBA | 24-FEB-00 | TMCM | 13-MAR-19 | A | |
| 271 | BIOSND | RN | Bioclastic sand deposit - A type of biological sediment. It consists of sand composed of broken and fragmental remains of organisms including shells, coral and lithothamnium algae.

| 272 | BITCOL | RN | Bituminous-coal - A type of coal. It is a member of the pure humic coal series. The members of the pure humic coal series can be ranked in order as peat (the unlithified form), lignite, bituminous-coal, and anthracite (the lithified forms) based on increasing carbon content and decreasing volatile content. Bituminous-coal is a black, hard and bright coal which typically breaks into rectangular lumps. The bituminous coals can be subdivided in two ways. The first scheme is based on lithotypes which are macroscopically recognisable bands of coal seams. This scheme can be used for describing individual specimens or discrete horizons within a coal seam. Using this scheme, bituminous-coal can be subdivided into vitrain, clarain, fusain, and durain. The second scheme describes the brightness of the coal, and should be used in the field to describe megascopically distinct layers of coal seams. Using this scheme, bituminous-coal can be subdivided into bright-coal, banded-bright-coal, banded-coal, banded-dull-coal, and dull-coal.

| 277 | BLBTPH | RN | Block-bomb-tephra - A type of pyroclastic-sediment. In the Rock Classification Scheme, it is a pyroclastic-sediment in which the average size of more than 75% of the pyroclastic fragments exceeds 64 mm. Block-tephra, bomb-block-tephra, block-bomb-tephra, and bomb-tephra are separated according to the relative proportion of blocks (angular fragments exceeding 64 mm) and bombs (rounded fragments exceeding 64 mm): if between 25% and 50% of all pyroclastic fragments bigger than 64 mm are blocks the sediment is block-bomb-tephra. It is the unconsolidated equivalent of agglomerate. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4. | Block-bomb-tephra | C | AWEL | 17-DEC-04 | TMCM | 15-FEB-19 | I | R |
