Özet:

Random distribution of energy resources in the world, rapidly increasing energy prices, environmental problems such as global warming and climate change, the depletion of fossil fuels in the near future and their negative impact on the environment and human health, increasing dependence on foreign energy, limited energy resources of big consumer countries and being dependent on a small number of specific countries lead states to seek various sources of energy. The uranium fuel-based nuclear energy generation is an alternative energy source for Turkey. Proven uranium reserves in Turkey are 32.4 kt and exploration of sedimentary basins for uranium mineralization still continues. In this context, Dinar (Afyonkarahisar, western Turkey) coal occurences can attract attention for economic possibilities of uranium related with Plio-Miocene aged extensional tectonic regime. A total of 17 coal samples were collected for analyses from five boreholes at various depths. The uranium contents of studied coals are up to 1065 μg/g. The origin of the uranium in this basin are considered as a stratal epigenetic origin, which the uranium was introduced in the coal after coalification and consolidation of the enclosing sediments by ground water deriving uranium from hydrothermal sources or from unconformably overlying volcanic rocks. In addition, it can be highlighted that the higher contents of uranium occur in the upper parts of the stratigraphically highest lignite beds, which is compatible with other epigenetic lignite deposits.
