| 2766 | ULMYL | Ultramylonite - A type of mylonitic-rock. In the Rock Classification Scheme, it is one in which porphyroclasts comprise less than 10% by volume of the rock. British Geological Survey Research Report RR/99/02, section 7.3 and table 5. | R | Ultramylonite | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | Deformed (ductile), intensely foliated rock (protolith unidentifiable) with primary cohesion, containing <10% porphyroclasts (commonly lensoid with tails indicating shearing sense) in a finer grained dynamically recrystallised matrix | C | |||||
| 2767 | UMFT | Ultramafitite - A type of mafite. In the Rock Classification Scheme, it is the fine-grained equivalent of ultramafic-rock. The term may be used as a field classification when an accurate mineral mode from thin section examination, or a chemical analysis, is not available.

| 2768 | UMMER | Ultramafic-melilitic-rock - A type of melilitic rock. In the Rock Classification Scheme, ultramafic-melilitic-rock and non-ultramafic-melilitic-rock are distinguished using colour index M: ultramafic-melilitic-rock has M greater than 90%. British Geological Survey Research Report RR/99/06, section 6.2 and figs. 27, 28. | A | Ultramafic-melilitic-rock | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | Exotic crystalline intrusive/extrusive rock, CI M>90%; >10% modal melilite, <90% clino-pyroxene, <90% olivine of Mel+Cpx+Ol; includes all known melilitic rock types | C | |||||
| 2769 | UMR | Ultramafic-rock - A type of coarse-grained normal crystalline rock. In the Rock Classification Scheme, a rock is ultramafic if the proportion of mafic minerals (M) is greater than 90%. They are classified according to their mafic mineral content, namely olivine, orthopyroxene, clinopyroxene and hornblende. The class includes peridotite, pyroxenite, and hornblendite. The term may be used as a field classification when an accurate mineral mode from thin section examination is not available.

| 2773 | UPRO | Metamorphic rock with unknown protolith - In the Rock Classification Scheme, a rock is classified within this category if the nature of the protolith is not known. The class includes metamorphic rock with unknown protolith based on textural attributes, and metamorphic rock with unknown protolith based on modal composition.
