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.

| 2681 | PN | RN | Phonolite - A type of phonolitic-rock. In the Rock Classification Scheme, this name is used for a fine-grained crystalline igneous rock when the modal mineralogy is available, and the mineral mode plots in field 11 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17a, 19. | Phonolite | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 2682 | PNBSN | RN | Phonolitic-basanite - A type of tephritic-rock. In the Rock Classification Scheme, this name is used for a fine-grained crystalline igneous rock when the modal mineralogy is available, and the mineral mode plots in field 13 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. Phonolitic-basanite and phonolitic-tephrite are distinguished by the amount of olivine in the CIPW norm: if normative olivine exceeds 10% the rock is phonolitic-basanite.

| 2684 | PNLUC | RN | Phonolitic-leucitite - A type of leucitite. In the Rock Classification Scheme, this rock plots in field 15a on the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram; foids constitute 60 to 90% of light-coloured constituents; alkali feldspar is dominant over plagioclase.

| 2685 | PNR | RN | Phonolitic-rock - A type of mafite. In the Rock Classification Scheme, this class includes phonolite and similar rocks. The term may be used as a field classification when an accurate mineral mode from thin section examination, or a chemical analysis, is not available.

| 2687 | PNT | RN | Phonolite (TAS) - A type of phonolitic-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 phonolite (TAS) is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20. | Phonolite (TAS) | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |

In the Rock Classification Scheme, this name is used for a fine-grained crystalline igneous rock when the modal mineralogy is available, and the mineral mode plots in field 13 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. Phonolitic-basanite and phonolitic-tephrite are distinguished by the amount of olivine in the CIPW norm: if normative olivine is less than 10% the rock is phonolitic-tephrite.

| 2689 | PNTEPT | RN | Phono-tephrite - A type of tephritic-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 phono-tephrite is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20. | Phono-tephrite | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 2690 | PORCEL | RN | Porcellanite - A type of siliceous rock. It usually has a porosity of 15 to 30%. Porcellanites have the texture, lustre and conchoidal fracture of porcelain. They can be further classified as opaline-porcellanite and quartzose-porcellanite according to the type of silica. It may not be possible to accurately use this classification without X-ray analysis.
