375	CNMST	Cannel-mudstone - A type of sedimentary-rock rich in organic matter. Sapropelite and cannel-mudstone are both derived from the unlithified fine organic mud termed sapropel. These sapropels contain more inorganic matter and plant matter than the sapropels that form sapropelic coals. Inorganic sedimentary rocks rich in sapropel are classified according to their type of organic matter. Sapropelite is rich in alginite, whereas cannel-mudstone is rich in miospores. In the Rock Classification Scheme, it is recommended that total organic content (TOC) for cannel-mudstone should be between 8% and 50%. British Geological Survey Research Report RR/99/03, section 6.3, table 18 and fig. 10.	R	Cannel-mudstone				GRBA	24-FEB-00	TMCM	08-MAR-19		Sedimentary rock, particles >50% or predominantly mud-grade, <0.032mm. Organic component sapropelic miospores > aliginite.

379	COLLW	Colliery waste - A type of artifical deposit. It consists of heterolithic waste material produced from the mining of coal or associated ironstone and fireclay. It is commonly a mixture of mudstone, siltstone, sandstone, carbonaceous shale and coal, with minor amounts of ironstone. It may contain secondary minerals such as pyrite and sulphur. British Geological Survey Research Report RR/99/04, appendix 1. Synonyms: spoil, tip, bing (Scotland).	R	Colliery waste				GRBA	24-FEB-00	TMCM	13-MAR-19		Not Available	C
