| Özet |
| In this study uranium and thorium contents and depositional characteristics of Çayirhan bituminous shales (ÇBS), west of Ankara (central Anatolia), are investigated. Samples used were collected from boreholes opened by Park Holding Ltd. A total of 25 samples were taken from bituminous shale levels in boreholes drilled at 6 different locations in the study area. The Hirka formation which hosts bituminous shale deposits is a volcano sedimentary sequence and all lithofacies indicate that a lacustrine environment where the water level was continuously changed. In addition to hydrocarbon generation potential, bituminous shales also accumulate significant amount of radioactive elements such as uranium and thorium. The average uranium and thorium concentrations of ÇBS (1.83/2.62 ppm) are much lower than averages of UC, NASK and PAAS (uranium: 2.70/2.66/3.10 ppm; thorium: 8.50/12.30/14.60 ppm). Low … |
