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%.
