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.

| 721 | FDIR | RN | Foid-dioritic-rock - A type of coarse-grained normal crystalline rock. In the Rock Classification Scheme, this class includes nepheline-diorite and similar rocks. The term may be used as a field classification when an accurate mineral mode from thin section examination is not available. British Geological Survey Research Report RR/99/06, section 5.1 and figs. 9, 10. | Foid-dioritic-rock | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | A | |
| 722 | FDIT | RN | Foidite (TAS) - A type of foiditic-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 foidite (TAS) is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20. | Foidite (TAS) | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 723 | FDO | RN | Foidolite - A type of foidolitic-rock. In the Rock Classification Scheme, it is a coarse-grained crystalline igneous rock whose mineral mode plots in field 15 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. This field contains rocks in which the light-coloured minerals are almost entirely feldspathoids. The fine-grained equivalent is foidite.

| 725 | FDOR | RN | Foidolitic-rock - A type of coarse-grained normal crystalline rock. In the Rock Classification Scheme, this class includes leucitolite and nephelinolite. The term may be used as a field classification when an accurate mineral mode from thin section examination is not available. British Geological Survey Research Report RR/99/06, section 5.1 and figs. 9, 10. | Foidolitic-rock | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | A | |
| 726 | FDSY | RN | Foid-syenite - A type of foid-syenitic-rock. In the Rock Classification Scheme, it is a coarse-grained crystalline igneous rock whose mineral mode plots in field 11 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. British Geological Survey Research Report RR/99/06, section 5.1 and figs. 9, 11, 12. | Foid-syenite | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 727 | FDSYR | RN | Foid-syenitic-rock - A type of coarse-grained normal crystalline rock. In the Rock Classification Scheme, this class includes nepheline-syenite, nepheline-monzosyenite and similar rocks. The term may be used as a field classification when an accurate mineral mode from thin section examination is not available. British Geological Survey Research Report RR/99/06, section 5.1 and figs. 9, 10. | Foid-syenitic-rock | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | A | |
| 728 | FEBST | RN | Iron-boundstone - A type of ironstone, classified on the basis of its biogenic texture. It is an ironstone in which the original components were bound and encrusted together by the action of plants and animals in the position of growth. British Geological Survey Research Report RR/99/03, section 5.2, table 14 and fig. 9. | Iron-boundstone | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |
| 729 | FECRTE | RN | Ferricrete - A type of duricrust. It is a conglomerate consisting of surficial sand and gravel cemented into a hard mass by iron oxide derived from the oxidation of percolating solutions of iron salts. British Geological Survey Research Report RR/99/03, section 13.6; RR/99/04, appendix 2. Synonyms: iron laterite, iron pan. | Ferricrete | C | GRBA | 24-FEB-00 | TMCM | 13-MAR-19 | R | |
| 730 | FEFBT | RN | Ferroan-carbonatite - A type of carbonatite. In the Rock Classification Scheme, this term may be used when a modal classification is possible. In a ferroan-carbonatite, the main carbonate mineral is ferroan dolomite, ankerite or siderite. These can be distinguished from other carbonates by stain tests. British Geological Survey Research Report RR/99/06, section 6.1 and fig. 25. See also: ferrocarbonatite. | Ferroan-carbonatite | C | AWEL | 10-JUN-02 | TMCM | 22-FEB-19 | R | |

| 733 | FEGV | RN | Iron-gravel - A type of iron-sediment. In the Rock Classification Scheme, it is one in which over 25% of clasts are larger than 2 mm. The grain size classes are defined in the same way as the siliciclastic sediments. British Geological Survey Research Report RR/99/03, section 5.1, table 13 and fig. 9.
