Cannel Coal


a variety of sapropelic fossil coal that is black with a grayish or slightly brown cast and a dull satiny luster. The fracture is flat-conchoidal and smooth, and the structure is massive. Because of the considerable density and viscosity of cannel coal, it can be used as a material for artistic and household items. Under a microscope, cannel coal is an aggregate chiefly of microspores and sparse fragments of megaspores in a brown basic mass without fusite or larger plant remains. The basic mass is sapropelic with an admixture of humus matter. Cannel coal has a high hydrogen content (6–9 percent) and can be lit by a match. It is found in coal seams in the form of intercalations or lenses.
