| Clinopyroxene-micronorite - A type of microgabbro. In the Rock Classification Scheme, it is the medium-grained equivalent of clinopyroxene-norite. British Geological Survey Research Report RR/99/06, section 5.1. | MCCPXN |
| Foid-bearing-microgabbro - A type of microgabbroic-rock. In the Rock Classification Scheme, it is the medium-grained equivalent of foid-bearing gabbro. British Geological Survey Research Report RR/99/06, section 5.1. | MCFBGB |
| Foid-bearing-micromonzogabbro - A type of microgabbroic-rock. In the Rock Classification Scheme, it is the medium-grained equivalent of foid-bearing-monzogabbro. British Geological Survey Research Report RR/99/06, section 5.1. | MCFBMG |
| Foid-microgabbro - A type of foid-microgabbroic-rock. In the Rock Classification Scheme, it is the medium-grained equivalent of foid-gabbro. British Geological Survey Research Report RR/99/06, section 5.1. | MCFDGB |
| Foid-microgabbroic-rock - A type of medium-grained normal crystalline rock. In the Rock Classification Scheme, it is the medium-grained equivalent of foid-gabbroic-rock. The class includes analcime-microgabbro, nepheline-micromonzogabbro 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. | MCFGBR |
| Foid-micromonzogabbro - A type of foid-microgabbroic-rock. In the Rock Classification Scheme, it is the medium-grained equivalent of foid-monzogabbro. British Geological Survey Research Report RR/99/06, section 5.1. | MCFMGB |
