clarite

A coal microlithotype that contains a combination of vitrinite and exinite totalling at least 95%. The proportions of these two macerals may vary widely, but each must be greater than the proportion of inertinite, and neither must exceed 95%. Distinction may be made between spore clarite, cuticular clarite, and resinous clarite. Clarite is widely distributed and very common, particularly in clarain-type coals and occurs in fairly thick bands. Compare: clarain.
