- Abstract
In this study, TOC content, Re-Mo enrichment and depositional environment of oil shale deposits in NW Anatolia are investigated. The Hatıldağ, Himmetoğlu, Beypazarı, Bahçecik, Seyitömer and Gölpazarı oil shale units are characterized by average TOC values 5.62; 6.52; 7.73; 8.68; 12.85 and 6.85 wt.%, average Re concentrations 5.52; 3.55; 5.77; 4.45; 2.43 and 10.43 ng/g, and average Mo concentrations 2.86; 1.60; 10.17; 1.00; 1.63 and 7.11 µg/g, respectively. Although the data on TOC content are similar, Re and Mo content of these oil shales is lower than those of the marine black shales of the Norwegian and Cenomanian-Turonian boundary event (CTBE) and of Mediterranean sapropels. Re and Mo concentrations in all Turkish oil shale areas are higher with respect to average values for shales. The enrichment factors (EF) for Re and Mo are the highest for Beypazarı -- 310-107, and the lowest for Bahçecik -- 35.17-1.57. The following significant correlations were established: Re-Mo for Hatıldağ, Re-TOC and Re-U for Himmetoğlu, Re-Mo and U-TOC for Beypazarı, Re-Mo and Re-U for Bahçecik and Re-TOC, Mo-TOC, U-TOC, Re-U and Mo-U for Seyitömer oil shales. No significant correlation was determined between any of the variables from the Gölpazarı field.
