This study focuses on major and trace element concentrations of three lignite samples, of which two are from the working lignite seam and one from a feed coal to Çan thermal power plant. The Çanakkale-Çan lignite deposit is currently being mined by open-cast mining methods despite its high sulfur content. The production lignites are mainly consumed by Çan fluidized-bed thermal power plant with 2 160 MW capacity and less domestic heating and industrial factories around Çan. Major oxide compositions of the coal ash samples imply that the more abundant oxides are SiO 2 and Al 2 O 3 and less CaO and Fe 2 O 3 . Trace element concentrations in the samples on whole-coal basis show that three samples analyzed were enriched in V, and also concentrations of B, Sc, Sn, Th, Tl, and U in one sample that exceed the range values of most world coals.

TheÖren and Yatagan Basins in SW Turkey host several Miocene coal deposits currently under exploitation for power generation. The present study aims to provide insight into the palaeoenvironmental conditions, which controlled the formation of the Hüsamlar coal seam located inÖren Basin. The coal seam displays many sharp alternations of matrix lignite beds and inorganic, lacustrine sediment layers. The coal is a medium-to-high ash lignite (10.47-31.16 wt%, on dry basis) with high total sulphur content (up to 10 wt%, on dry, ash-free basis), which makes it prone to self-combustion. The maceral composition indicates that the peat-forming vegetation consisted of both arboreal and herbaceous plants, with the latter being predominant in the upper part of the seam. Mica and feldspars contribute to the low part of the seam; carbonates are dominant in the upper part, whereas quartz and pyrite are present along the entire coal profile. The sudden transitions of the telmatic to the lacustrine regime and reverse is attributed to tectonic movements that controlled water table levels in the palaeomire, which affected surface runoff and hence, clastic deposition.
