| 2186 | OSCH | Orthoschist - A type of meta-igneous 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 ortho- prefix indicates a rock that is thought to have an igneous protolith, in contrast with paraschist which has a sedimentary protolith, and schist where the nature of the protolith is not defined. British Geological Survey Research Report RR/99/02, sections 3.3, 5.3 and fig. 1. | R | Orthoschist | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | Medium-grained (av. 0.25-2mm) strongly foliated meta-igneous rock; (protolith undefined) splits into < 5mm slabs/flakes defined by well-developed planar orientation of platy/prismatic minerals | C | |||||

| 2188 | P | Peat [Unlithified Deposits Coding Scheme] - A type of natural superficial deposit. The Unlithified Deposits Coding Scheme was developed as a way of coding unlithified deposits (also commonly referred to as superficial deposits, unconsolidated deposits, or engineering soils) that is consistent with civil engineering industry usage (BS5930). See also: peat. | R | Peat [UDCS] | AWEL | 09-JAN-02 | TMCM | 13-MAR-19 | Not Available | C | |||||

| 2191 | PAMPHB | 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. | R | Para-amphibolite | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | Crystalloblastic commonly foliated meta-sedimentary rock (grain size & protolith undefined); 35-90% mafic minerals hornblende+plagioclase dominant +/-garnet/biotite/quartz | C | |||||

| 2198 | PCR | Picritic-rock - A type of mafite. Picritic rocks are high-Mg fine-grained crystalline rocks. They are classified using an extension of the total alkali silica (TAS) classification.
