Grahamite
From Wikipedia, the free encyclopedia
Grahamite, also known as Pyrobitumen or Anthraxolite,[1] is a bitumen-impregnated rock (asphaltite). It is a naturally occurring solid hydrocarbon bitumen with a relatively high fixed carbon rate of 35–55% and high temperature of fusion.[3] It occurs in Cuba, Mexico, and in West Virginia and Oklahoma, United States. Grahamite found in the Impson Valley of southeastern Oklahoma is known as impsonite.
