Retinite

Retinite is resin, particularly from beds of brown coal which are near amber in appearance, but contain little or no succinic acid. It may conveniently serve as a generic name, since no two independent occurrences prove to be alike, and the indefinite multiplication of names, no one of them properly specific, is not to be desired.[1][2]

Retinite resins contain no succinic acid and oxygen from 6% to 15%.[3]
