OIL SHALE, cilt.31, sa.4, ss.315-336, 2014 (SCI-Expanded)
In the Eskisehir Basin, western Turkey, oil shale occurs in alternation with claystone, siltstone, conglomerate and coal (lignite) seams in lacustrine deposits of Early-Middle Miocene age. The thickness of oil shale seams drilled during the study varies between 20 and 30 m. Organic geochemical features of the shale were evaluated using TOC, pyrolysis, GC and GC-MS analyses.
