ABSTRACT
Ceyhan et al. (2006) determined that Tunçbilek has mid-hard, black and bright coal. Besides, non-coal interlayer are found relatively less in upper and bottom parts of the coal seam, while they are more frequent at the middle parts. It is also noted that the drill holes intersect tuff, claystone, limestone, sandstone, conglomerate, serpentine, periodite, dolomite and marl formations. Tunçbilek coal basin comprises two series of Neogen sediments.The lower one is called theTunçbilek series and is in discordantly on an ophiolitic basement. The coal seam is in this series. The upper one is called the Domaniç series and this younger series lies on the Tunçbilek series with slight discordance (Bas¸arır et al. 2004). The thickness of the marl formations in the Southern part of the basin, especially in production areas reach at 400-450 m. Lower levels of Marl layers include economical lignite formations. This unit generally has marl, siltstone, limestone and milestone, sandstone and conglomerate (Tas¸kın, 1999).
