2306	PSAMM	Psammite - A type of metasedimentary rock composed largely of quartz, feldspar and mica. In the Rock Classification Scheme, it is one with mica component <20%, and quartz + feldspar 80 - 100% 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	Psammite				GRBA	24-FEB-00	TMCM	22-FEB-19		Metasedimentary rock (grain size & protolith undefined); modal composition <10% calc-silicate/carbonate minerals, >80% Q+F, <20% other minerals (mica/chlorite/garnet/cordierite/staurolite/Al-silicate minerals)	C

2309	PSCH	Paraschist - A type of metasedimentary rock based on textural attributes. In the Rock Classification Scheme, it is defined as a medium-grained strongly foliated rock that can be readily split into flakes or slabs due to the well-developed preferred orientation of the majority of the minerals present, particularly those of platy or prismatic habit. Schists occur characteristically in areas of medium-grade metamorphism and can encompass a wide range of lithologies. Note the para- prefix indicates a rock that is thought to have a sedimentary protolith, in contrast with orthoschist which has an igneous protolith, and schist where the nature of the protolith is not defined. British Geological Survey Research Report RR/99/02, section 3.3.	R	Paraschist				GRBA	24-FEB-00	TMCM	22-FEB-19		Medium-grained (av. 0.25-2mm) strongly foliated meta-sedimentary rock; (protolith undefined) splits into < 5mm slabs/flakes defined by well-developed planar orientation of platy/prismatic minerals	C
