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.

| 2498 | NSLSD | RN | Non-clastic siliceous sediment - In the Rock Classification Scheme, these are sediments which are composed of more than 50% silica of biogenic or chemical origin. This is the unlithified equivalent of siliceous rock.

| 2500 | NSY | RN | Nepheline-syenite - A foid-syenite in which the dominant feldspathoid mineral is nepheline. British Geological Survey Research Report RR/99/06, section 5.1 and fig. 9. | Nepheline-syenite | C | AWEL | 02-JUL-01 | TMCM | 22-FEB-19 | R | |
| 2501 | NUMELR | RN | Non-ultramafic-melilitic-rock - A type of melilitic rock. In the Rock Classification Scheme, ultramafic-melilitic-rock and non-ultramafic-melilitic-rock are distinguished using colour index M: non-ultramafic-melilitic-rock has M less than 90%.

| 2502 | OAMPHB | RN | Ortho-amphibolite - A type of metamafic-rock. In the Rock Classification Scheme, it is one composed largely of hornblende and feldspar. This mineralogy reflects amphibolite facies conditions. Note the ortho- prefix indicates a rock that is thought to have an igneous protolith, in contrast with para-amphibolite which has a sedimentary protolith, and amphibolite where the nature of the protolith is not defined.

| 2504 | OBS | RN | Obsidian - A type of glassy-igneous-rock. It is a glassy, fresh, igneous rock. The term has no compositional inference. British Geological Survey Research Report RR/99/06, section 8.3. | Obsidian | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | A | |
| 2505 | OCHERT | RN | Opaline-chert - A type of chert in which the silica includes amorphous silica (opal-A), opal CT, low-cristobalite and tridymite. British Geological Survey Research Report RR/99/03, section 8.2 and fig. 12. | Opaline-chert | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |

| 2516 | OGNOF | RN | Orthogranofels - A type of meta-igneous rock based on textural attributes. It lacks any obvious foliation and layering and is commonly characterised by a granoblastic texture. A granofels can occur at any metamorphic grade with a range of lithologies. Note the ortho- prefix indicates a rock that is thought to have an igneous protolith, in contrast with paragranofels which has a sedimentary protolith, and granofels where the nature of the protolith is not defined.
