The Paleocene-Eocene lacustrine sedimentary succession in the east-west trending Hatildag oil shale held is 800 m thick and divided into the Hasanlar, Kabalar and Daghacilar formations. Oil shale bearing strata is in the middle part of the Kabalar formation. Mineral and maceral types show that the liptinite and bituminite tend to be associated with calcite. The negative correlation between trace elements and organic carbon suggests absence of enrichment of trace elements in oil shales.
