2438	REGOL	Regolith - A type of residual deposit. It is a general term used to describe the in situ or nearly in situ weathered products (including disintegrated rock, rock fragments and mineral grains) overlying fresh or relatively fresh rock (the weathered mantle). It can be subdivided into weathered rock and saprolite, and classified according to engineering geological weathered rock grades. British Geological Survey Research Report RR/99/04, appendix 2.

2443	RODT	Rodingites - A type of metasomatic-rock. They are rocks associated with serpentinites comprising Ca-rich minerals, for example Ca-pyroxene, grossular, hydrogrossular. They represent the Ca-rich fraction expelled during serpentinisation. British Geological Survey Research Report RR/99/02, section 8.	R	Rodingites			GRBA	24-FEB-00	TMCM	22-FEB-19		Metamorphic rock (grain size & protolith undefined) with significant chemically/mineralogy alteration, typically associated with serpentinite; Ca-rich minerals common, including Ca-pyroxene/grossular/hydro-grossular; a metasomatic rock	C
2444	RRM	Rock of restricted mineralogy - A type of coarse-grained normal crystalline rock. Igneous rocks of unusual composition can be formed by extreme versions of magma differentiation and fractionation. British Geological Survey Research Report RR/99/06, section 8.2.	A	Rock of restricted mineralogy			AWEL	09-OCT-01	TMCM	22-FEB-19		Not Available	C
2445	RY	Rhyolite - A type of rhyolitic-rock. In the Rock Classification Scheme, this name is used for a fine-grained crystalline igneous rock when the modal mineralogy is available, and the mineral mode plots in field 3 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. It is the fine-grained equivalent of granite. British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17a, 19.
