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.

| 1041 | KALI | RN | Kalsilitite - A type of kalsilitic rock. Kalsilitite is the general name for fine-grained kalsilitic rocks. At present, only one true kalsilitic rock is known, namely olivine-pyroxene kalsilitite, known formerly as mafurite, from Uganda. No coarse-grained rocks containing more than 10% modal kalsilite have been found so far, but if such a rock is found, it should be called a kalsilitolite following the convention used in melilitic rock.

| 1042 | KALO | RN | Kalsilitolite - A type of kalsilitic rock. No coarse-grained rocks containing more than 10% modal kalsilite have been found so far, but if such a rock is found, it should be called a kalsilitolite following the convention used in melilitic rock.

| 1043 | KALR | RN | Kalsilitic rock - A type of exotic crystalline igneous rock. In the Rock Classification Scheme, it is defined as a rock that contains more than 10% modal kalsilite. Kalsilite is a very rare mineral, and its presence is sufficiently important to merit defining rocks with notable kalsilite as a separate group. In the present scheme a threshold value of 10% modal kalsilite has been adopted, the same as the threshold for melilitic rock and leucitic rock. Kalsilite behaves metastably and only rarely survives slow cooling, so virtually all rocks containing kalsilite are fine- or very fine-grained lavas. Coarse-grained rocks containing kalsilite (e.g. kalsilite-bearing syenite and kalsilite-bearing-biotite pyroxenite) have been reported from Russia; however they are extremely rare.

| 1044 | KAOCLY | RN | Kaolinite-clay - A type of monomineralic aluminium-silicate sediment in which the aluminium-silicate mineral is kaolinite. It is the unlithified equivalent of kaolinite-claystone.

| 1045 | KAOCST | RN | Kaolinite-claystone - A type of monomineralic aluminium-silicate sedimentary rock in which the aluminium-silicate mineral is kaolinite. It is the lithified equivalent of kaolinite-clay. British Geological Survey Research Report RR/99/03, section 9.1 and table 19. Synonym: china clay. | Kaolinite-claystone | C | GRBA | 24-FEB-00 | TMCM | 13-MAR-19 | R | |
| 1046 | KERNST | RN | Kernite-stone - A type of non-carbonate salt that is composed of particles of the borate mineral kernite. British Geological Survey Research Report RR/99/03, section 7.1 and fig. 11. | Kernite-stone | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |
| 1047 | KERS | RN | Kersantite - A type of lamprophyre. In the Rock Classification Scheme, it is a lamprophyre in which plagioclase is the dominant feldspar, and the predominant mafic minerals are biotite and diopsidic augite (with/without olivine). British Geological Survey Research Report RR/99/06, section 6.7 and figs. 31, 32. | Kersantite | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 1048 | KIEST | RN | Kieserite-stone - A type of non-carbonate salt that is composed of particles of the sulphate mineral kierserite. British Geological Survey Research Report RR/99/03, section 7.1 and fig. 11. | Kieserite-stone | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |
| 1049 | KMB | RN | Kimberlite - A type of exotic crystalline igneous rock. Kimberlites are currently divided into two groups. Group-1-kimberlite corresponds to archetypal rocks from Kimberley, South Africa that formerly were termed basaltic kimberlites. Group-2-kimberlite corresponds to micaceous or lamprophyric kimberlites. Recent studies have demonstrated that these two groups are mineralogically different and petrogenetically separate rock types.
