asphaltite

[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].
There is a reason to believe that detailed examination of asphaltite deposits may offer rich information about possible oil pools which are also of continuously growing interest of scientists and practicians.
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.
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].
In Turkey, asphaltite is one of the large sources of energy in the southeastern part of the country, in the provinces of Siirt, Sirnak and Mardin.
Low oxygen content (< 2%) of asphaltite shows that asphaltite is of petroleum origin and has been formed through metamorphism.
