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.

| 3339 | TUF | RN | Tuff - A type of pyroclastic-rock. In the Rock Classification Scheme, it is a pyroclastic-rock in which the average size of more than 75% of the pyroclastic fragments is less than 64 mm. Lapillistone, lapilli-tuff, and tuff are separated according to the relative proportion of lapilli-grade (2 - 64 mm) and ash-grade (<2 mm) fragments: if less than 25% of the fragments are lapilli the rock is tuff. It is the consolidated equivalent of ash. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4. | Tuff | C | GRBA | 24-FEB-00 | TMCM | 15-FEB-19 | R | |
| 3340 | TUFA | RN | Tufa - A type of chemical deposit (natural superficial). It is a sedimentary rock composed of calcium carbonate or silica, formed by evaporation as a thin, surficial, soft, spongy, semifriable encrustation around the mouth of springs, seeps or along streams carrying calcium carbonate in solution, and exceptionally as a thick deposit along lake shores. Travertine is a hard, dense variety of tufa; it also occurs in caves as stalactites and stalagmites. British Geological Survey Research Report RR/99/03; RR/99/04, appendix 2 and tables 5, 17. Synonyms: sinter, travertine. | Tufa | C | GRBA | 24-FEB-00 | TMCM | 13-MAR-19 | R | |
| 3341 | TUFBRC | RN | Tuff-breccia - A type of pyroclastic-rock. In the Rock Classification Scheme, it is a pyroclastic-rock which contains more than 25% of each of the main pyroclastic fragment size divisions: blocks and bombs (>64 mm), lapilli (2 - 64 mm), and ash (<2 mm). It is the consolidated equivalent of ash-breccia. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4. | Tuff-breccia | C | GRBA | 24-FEB-00 | TMCM | 15-FEB-19 | R | |

| 3345 | TUFIST | RN | Tuffisite - A type of intrusion-breccia. It comprises brecciated and lithified country-rock fragments found in intrusive pipes which are formed by the explosive release of gas.

| 3347 | TUFT | RN | Tuffite - A type of volcaniclastic igneous rock and sediment. In the Rock Classification Scheme, tuffite is a general term for volcaniclastic rocks and sediments which consist of 25 - 75% by volume pyroclastic fragments. The class includes tuffaceous-sedimentary-rock, and tuffaceous-sediment.
