System:AmorphousColour:black


A widespread hydrocarbon mineraloid of variable composition. Differs from asphalt by being brittle, infusible and relatively insoluble. Formed by polymerization of petroleum over geological time periods, therefore being related to petroleum the same way that amber is related to tree resin. May be relatively enriched in N, S, and sometimes rare elements like U, V, Pt, etc.
