The microscopically recognizable organic material consists mainly of liptinite, huminite and prebitumen [12, 13].
Palynofacies analysis also indicated that Datta shales are rich in kerogen macerals, including inertinite, vitrinite, amorphinite ( Amorphous Organic Matter) with minor liptinite (i.
Liptinite in coal and oil source rocks in northern Thailand.
Liptinite macerals rarely exceed 15% and vanish with increasing depth (Kcdzior and Jelonek, 2013).
Generally, softness of coal increases with increasing vitrinite content and decreasing micronite and liptinite macerals.
Vitrinite can be separated by flotation process by taking advantage of differences in its hidrophobicity compared to liptinite and inertinite macerals, Sun (1954).
The Tertiary coals are humic and generally dominated by vitrinite, with significant amounts of liptinite and low amounts of inertinite macerals.
Petrographically these coals are rich in vitrinite and conspicuously deficient in liptinite macerals.
It has been reported that liptinite does not contribute significantly to char formation, but contributes to liberation volatile rate [Cloke, 1994; Valentim, 2004] and to the flame stability [Shibaoka, 1969], while the vitrinite and inertinite are considered precursors of the formed char type [Shibaoka, 1985].
GOS consists of more than 50% liptinite, 20-50% huminite, and 0-20% inertinite maceral groups and is characterized by high organic content.
