| 摘 要： | Bituminous rocks in the Ozankoey （Ankara） field are different from those of the Paleocene- Eocene Mengen and Giineytepe （Bolu） regions in metal enrichment levels. Organic carbon （Corg） content of organic material-rich rocks in the Ozankoey （Ankara） field is 3.66-40.72% wt averaging 14.34%. The dominant organic materials are algae/amorphous accompanied by minor amount of herbaceous material （The dominant kerogen type is Type-I with a limited amount of Type-Ⅱ kerogen.）. The bituminous rocks in the Ozankoey field are enriched in heavy metals such as Ni, Mn, As and Cr. In comparison with the average enrichment values of dements, Ni, Mn, As and Cr in bituminous shales of the Ozankoey field are as about 4.38, 14.93, 10.90 and 5.58 times as average values. The average concentrations of these heavy metals are also as high as 215× 10^-6, 828 × 10^-6, 58.54 × 10^-6, and 148 × 10^-6 respectively. In addition, sorption properties of day and organic materials are also important for metal enrichments in the bituminous shales.

| Abstract: | Abstract: Bituminous rocks in the Ozanköy (Ankara) field are different from those of the Paleocene‐Eocene Mengen and Güneytepe (Bolu) regions in metal enrichment levels. Organic carbon (Corg) content of organic material‐rich rocks in the Ozanköy (Ankara) field is 3.66‐40.72% wt averaging 14.34%. The dominant organic materials are algae/amorphous accompanied by minor amount of herbaceous material (The dominant kerogen type is Type‐I with a limited amount of Type‐II kerogen.). The bituminous rocks in the Ozanköy field are enriched in heavy metals such as Ni, Mn, As and Cr. In comparison with the average enrichment values of elements, Ni, Mn, As and Cr in bituminous shales of the Ozanköy field are as about 4.38, 14.93, 10.90 and 5.58 times as average values. The average concentrations of these heavy metals are also as high as 215 times 10?6, 828 times 10?6, 58.54 times 10?6, and 148 times 10?6 respectively. In addition, sorption properties of clay and organic materials are also important for metal enrichments in the bituminous shales. |
