Abstract
The study area is located at southwest of Göynük (Bolu) in Paleocene-Eocene Hatıldağ Formation. A Scaled Stratigraphic Column has been done with 323 m thickness and total of 113 samples were collected from study area. Interbedded oil shale, bituminous marn and limestone layers are dominant throughout the stratigraphic section. The geochemical analyses were carried out on collected samples and the contents of major, trace and REE (Rare Earth Elements) have been determined. The element enrichments of bituminous rocks were determined in studied area within the scope. Obtained element abundances were correleted with the organic rocks belonging to the certain earth’s redox/sulfidic depositional enviroments and the amounts of enrichment were determined. Considerable element enrichments in studied area are Ti, Fe, Mg, Ca and K as major elements and As, Cr, Mn, Ni, Rb, Sr and Zn as trace elements.
