[a′sfȯl‚tīt]
(geology)
Any of the dark-colored, solid, naturally occurring bitumens that are insoluble in water, but more or less completely soluble in carbon disulfide, benzol, and so on, with melting points between 250 and 600°F (121 and 316°C); examples are gilsonite and grahamite.

South-Eastern region of Turkey has a relatively large asphaltite potential [1-7].
Asphaltite is a solid petroleum fuel with a high softening point.
As the pyrolysis reaction runs, the coke aggregates and accumulates on the solid surface of the asphaltite. It is formed by several related mechanisms including dehydrogenation, polymerization and condensation of both light olefinic and heavy aromatic compounds.
Asphaltite is a petroleum-originated substance formed by metamorphism.
According to the World Energy Council and Turkish National Committee (1998), the total reserve of asphaltic substances which are found in southeastern Turkey is about 82 million tonnes, with Silopi and Sirnak reserves together comprising the major part of the asphaltite deposits.
These resources include a wide variety of bituminous coal, lignite, oil shale, asphaltite, and peat deposits and vary in reserve quality and physical characteristics [4].
