Concentrations of elements in Lias coals from the eastern Black Sea Region, NE-Turkey

Abstract

The element contents and organic matter-element relation between Lias-aged coals exposed in four fields in Gumushane and Bayburt were investigated. In general, fixed carbon and gross calorific values of the Edire and Balkaynak coals are higher than Guvercinlik and Cerci coals. The highest ash yields were observed in the Cerci coals. The concentrations of Mg, P, Ca, Mo, Y, Ni, U, Zn, Ga, Ba, W, Sr, Ta, and Be of the analysed coals are positively correlated with ash yield, indicating an organic affinity. The Lias-aged coals located in Gumushane and Bayburt are low-rank coals.
