Grahamite

Grahamite is a bitumen-impregnated rock (asphaltite). It is a naturally occurring solid hydrocarbon bitumen with relatively high fixed carbon rate of 35–55% and high temperature of fusion.[1] 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.

Grahamite was named by Henry Wurtz after James Lorimer Graham, who was interested of commercial development of this mineral resource in West Virginia.[2]
