ABSTRACT

This study was carried out in Hazro-Diyarbakir region (SW of Turkey), which owns a
very unique coal formation. Aside from Zonguldak region (NW of Turkey), Paleozoic
coal formations are very rare in Turkey. Hazro region comprises the oldest units of the
region which was outcropped due to a considerably spectacular form of an anticline.
Diyarbakır-Hazro occurrences are outcropped within the Hazro anticline. The anticline
was emerged through a vast Tertiary Basin in the area. Gomaniibrik Formation, of
Upper Permian age, is the main formation of the region. The formation which contains
of shale, sandstone succession and is of lacustrine type formation comprises of two
important coal levels.
Chemical and petrographic analyses of the coals were taken into consideration. Coal
quality investigation along with proximate (moisture, volatile matter, fixed carbon, ash)
analyses were performed and revealed. The coals herein, as a result of conducted detail
prospects and drills, comprises of 0.2 – 1.9 meter thickness, 1.2 % moisture, 30 % ash,
5100 Kcal/kg calorific value and 2.3 million total reserve. The vitrinite (huminite) is the
most common maceral and its reflectances (Rmax) were found to be between 0.46 and
1.14% which refer to medium maturity levels. The coals seem to show sub-bituminous
to bituminous coal ranks. The mineral matters of the Hazro coals are mostly clays,
calcite and pyrite.
