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.

1138 LPDLRM  RN  Lamproite, diopside-leucite-richterite-madupitic - A type of lamproite. The term madupitic indicates that the rock contains poikilitic groundmass phlogopite, as opposed to a phlogopite lamproite in which the phlogopite occurs as phenocrysts.

1144 LPST  RN  Lapillistone - 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 more than 75% of the fragments are lapilli the rock is lapillistone. It is the consolidated equivalent of lapilli-tephra. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4.  Lapillistone  C  GRBA  24-FEB-00  TMCM  15-FEB-19    R 
1145 LPTPH  RN  Lapilli-tephra - A type of pyroclastic-sediment. In the Rock Classification Scheme, it is a pyroclastic-sediment in which the average size of more than 75% of the pyroclastic fragments is less than 64 mm. Lapilli-tephra, lapilli-ash, and ash are separated according to the relative proportion of lapilli-grade (2 - 64 mm) and ash-grade (<2 mm) fragments: if more than 75% of the fragments are lapilli the sediment is lapilli-tephra. It is the unconsolidated equivalent of lapillistone. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4.  Lapilli-tephra  C  GRBA  24-FEB-00  TMCM  15-FEB-19    R 
1146 LPTUF  RN  Lapilli-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 between 25% and 75% of the fragments are lapilli the rock is lapilli-tuff. It is the consolidated equivalent of lapilli-ash. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4.  Lapilli-tuff  C  GRBA  24-FEB-00  TMCM  15-FEB-19    R
