2208	PDT	Peridotite - A type of ultramafic-rock. In the Rock Classification Scheme, it is a coarse-grained ultramafic rock with more than 40% olivine.

2212	PEAT	Peat - A type of sediment rich in organic matter. It is the unlithified end-member of the pure humic coal series. The members of the pure humic coal series can be ranked in order as peat (the unlithified form), lignite, bituminous-coal, and anthracite (the lithified forms) based on increasing carbon content and decreasing volatile content. Peat is an unconsolidated deposit of semi-carbonised plant remains, with individual plant remains commonly seen with the unaided eye. Peat has a yellowish brown to brownish black colour, is generally of a fibrous consistency and can be plastic or friable. In its natural state it can be cut and has a very high moisture content (> 75%, generally > 90%). It can be distinguished from lignite by the fact that the greater part of its moisture content can be squeezed out by pressure (e.g. in the hand). British Geological Survey Research Report RR/99/03, section 6.1, table 16 and fig. 10.	R	Peat				GRBA	24-FEB-00	TMCM	08-MAR-19		Unlithified heterogeneous mixture of a wide range of semi-carbonised plant debris, individually discernable. Brown to black, plastic/friable/cut by knife, 75 to >90% water. Hand squeezing releases water, <60% carbon , dry, ash-free. Volatiles >63%.	C

2214	PEG	Pegmatite - A type of coarse-grained normal crystalline rock. In the Rock Classification Scheme, the term pegmatite is used for veins comprised of coarse or very coarse crystals. The term is used with qualifiers to describe component minerals in increasing abundance, for example biotite-quartz-feldspar pegmatite. British Geological Survey Research Report RR/99/06, section 8.1.

2222	PEL	Pelite - A type of metasedimentary rock composed largely of quartz, feldspar and mica. In the Rock Classification Scheme, it is one with mica component >40%, and quartz + feldspar <60% of quartz + feldspar + mica. The mica component includes all minerals other than quartz and feldspar, with the exception of calcsilicate and carbonate minerals. British Geological Survey Research Report RR/99/02, section 3.2, table 1 and fig. 5.	R	Pelite				GRBA	24-FEB-00	TMCM	22-FEB-19		Meta-sedimentary rock (grain size & protolith undefined); modal composition <10vol% calc-silicate/carbonate minerals, <60% Q+F, >40% other minerals (micas/chlorite/garnet/cordierite/staurolite/Al-silicate minerals (andalusite/kyanite/sillimanite))	C
