Asphaltic pyrobitumen

The heavy, viscous petroleum substances impregnating the tar sands are called asphaltic oils. Other names used to describe these oils include maltha, brea, and chapapote. Asphaltic petroleums are most commonly confused with, but are not related to asphaltites (gilsonite, glance pitch, and grahamite) the asphaltic pyrobitumens (elaterite, wurtzilite, albertite, and impsonite) the native mineral wax (ozokerite) and the pyrogenous distillates of bituminous substances (tar and pitch). 

Asphaltic pyrobitumens n. Include elaterite, impsonite, and wurtzlite. They are characterized by their hydrocarbon nature, infusibility, and insolubility in carbon disulfide. Oxygen-containing compounds are present only in small amounts. Usmani AM (1997) Asphalt science and technology. Marcel Dekker, New York. 

Elaterite i- la-t3r- rit [Gr Elaterit, fr. Gk elater] (1826) n. Infusible asphaltic pyrobitumen of petroleum origin, sometime described as mineral rubber or mineral Caoutchouc.
