|---|---|
| Mineral-type-clay (specified mineral) - A type of monomineralic aluminium-silicate sediment. British Geological Survey Research Report RR/99/03, section 9.1 and table 19. | MINCLY |
| Metalimestone and calcsilicate-rock | MLMC |
| Monomineralic meta-aluminium-silicates | MMALS |
| Monomineralic aluminium-silicate metasedimentary rock | MMNORC |
| Monomineralic aluminium-silicate sediment - These sediments take the form of clays. This is the unlithified equivalent of monomineralic aluminium-silicate sedimentary rock. British Geological Survey Research Report RR/99/03, section 9.1 and table 19. | MNASSD |
| Monomineralic aluminium-silicate sedimentary rock - These rocks take the form of claystones. This is the lithified equivalent of monomineralic aluminium-silicate sediment. British Geological Survey Research Report RR/99/03, section 9.1 and table 19. | MNOROC |
| Micaceous psammite, semipelite and calcsilicate-rock | MPSC |
| Metasedimentary rock composed largely of calcsilicate and/or carbonate minerals - A class within metasedimentary rock based on modal composition. In the Rock Classification Scheme, these are metamorphic rocks containing more than 50% calcsilicate and/or carbonate minerals. This class includes calcsilicate-rock, and metacarbonate-rock. British Geological Survey Research Report RR/99/02, section 3.2 and figs. 6, 7. | MRCCBM |
| Metasilicate-conglomerate | MSICOG |
| Metasilicate-mudstone | MSIMST |
| Metasilicate-siltstone | MSISLT |
| Metasilicate-sandstone | MSISST |
| Metasilicate-mudstone, dolomitic | MSMSTD |
| Metasilicate-mudstone, fissile | MSMSTF |
| Metasilicate-claystone | MSRCST |
| Metasilicate-sandstone, dolomitic | MSSDTD |
| Metasilicate-sandstone, coarse | MSSSTC |
| Metasilicate-sandstone, calcite-cemented | MSSTCC |
| Mineral-type-claystone (specified mineral) - A type of monomineralic aluminium-silicate sedimentary rock. British Geological Survey Research Report RR/99/03, section 9.1 and table 19. | MTCST |
| Para-amphibolite - A type of calcsilicate-rock. In the Rock Classification Scheme, it is one composed largely of hornblende and plagioclase. This mineralogy reflects amphibolite facies conditions. Note the para- prefix indicates a rock that is thought to have a sedimentary protolith, in contrast with ortho-amphibolite which has an igneous protolith, and amphibolite where the nature of the protolith is not defined. British Geological Survey Research Report RR/99/02, section 3.2. | PAMPHB |
