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.

| 2918 | RYT | RN | Rhyolite (TAS) - A type of rhyolitic-rock, classified using the total alkali silica (TAS) classification. The TAS classification may be used if the mineral mode of a normal fine-grained crystalline rock cannot be determined due either to the presence of glass or to the fine-grained nature of the rock. The definition of rhyolite (TAS) is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20. | Rhyolite (TAS) | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |

| 2922 | S | RN | Sand [Unlithified Deposits Coding Scheme] - A type of natural superficial deposit. The Unlithified Deposits Coding Scheme was developed as a way of coding unlithified deposits (also commonly referred to as superficial deposits, unconsolidated deposits, or engineering soils) that is consistent with civil engineering industry usage (BS5930). | Sand [UDCS] | C | AWEL | 09-JAN-02 | TMCM | 13-MAR-19 | R | |

| 2933 | SANN | RN | Sannaite - A type of lamprophyre. In the Rock Classification Scheme, it is a lamprophyre in which orthoclase is the dominant feldspar, feldspar dominates over feldspathoids, and the predominant mafic minerals are amphibole, Ti-rich augite, olivine, and biotite.

| 2935 | SAPEL | RN | Sapropelite - A type of sedimentary-rock rich in organic matter. Sapropelite and cannel-mudstone are both derived from the unlithified fine organic mud termed sapropel. These sapropels contain more inorganic matter and plant matter than the sapropels that form sapropelic coals. Inorganic sedimentary rocks rich in sapropel are classified according to their type of organic matter. Sapropelite is rich in alginite, whereas cannel-mudstone is rich in miospores. The total organic carbon content (TOC) can vary from less than 1% to as much as 81% in a sapropelite from Tasmania, although most sapropelites fall in the range of 8 to 55% TOC. In the Rock Classification Scheme, it is recommended that the lower limit for sapropelite should be 8% TOC and the upper limit 50% TOC. A sapropelite can be recognised in hand specimen by its bituminous smell and by the curled sliver of rock produced when it is scraped with a pen knife. Sapropelites can be subdivided into lamalginite and telaginite by reference to the properties of the organic matter. British Geological Survey Research Report RR/99/03, section 6.3, table 18 and fig. 10. Synonym: oil shale. | Sapropelite | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | A | |
| 2936 | SAPRO | RN | Saprolite - A type of regolith. It consists of highly to completely weathered materials derived from the in situ alteration and decomposition of parent rock mainly by chemical weathering processes, but which retain evidence of the original rock texture, fabric and structure. It may be classified as engineering soils falling into rock weathering grades IV (highly weathered) and V (completely weathered); that is, those weathering grades where more than 50% of the parent rock material is decomposed or disintegrated to soil.

| 2937 | SARCST | RN | Silicate-claystone - A type of silicate-mudstone. In the Rock Classification Scheme, it is a silicate-mudstone consisting of greater than 50% clay-grade particles. The rock is extremely fine-grained with a homogeneous appearance.
