ABSTRACT

This study was carried out in Halifan (Bingol) region (East of TURKEY), which owns a
unique coal formation in the region. Chemical, petrographic analysis and organic
geochemical evaluations of the Tertiary aged coals were taken into consideration. Coal
quality investigation along with proximate (moisture, volatile matter, fixed carbon, ash)
and elemental analyses (C, H, O, S, N) were performed and revealed. The huminite
reflectances of organically abundant matter and coal levels were found to be between
0.368 and 0.573% which refer to lower maturity levels. This parameter is compatible
with fluorescence colors, calorific (average 2736 (original) – 3727 (dry) Kcal/kg) and
average Tmax (417oC) values. Organic matters of the investigated coals exhibit
predominantly medium grade transformation, due to the extensively effective main
faults in the region. Halifan coals show low-medium grade maturity and own subbituminous
and lignite coalification ranks.
Rock Eval analysis results show that TYPE II/III and III kerogen, with average Tmax
values is 417oC and corresponding to the immature and premature rank for hydrocarbon
generation. The coals are characterised with their abundance of huminite maceral group
and gelinite maceral, with small amount of inertinite and liptinite macerals. The coals
were deposited in a lake environment. Mineral matters of the Bingol Karliova coals are
clays, quartz and feldspar minerals..
