The paper is devoted to the analysis of results of field studies carried out during the period from 2007 to 2011 in the Black Sea coastal zone from the Strait of Kerch to the city of Tuapse. In totality 164 samples of fresh and weathered oil slicks were taken and studied using thin-layer chromatography, gravimetrical and optical methods. The geographical peculiarities of oil slicks distribution are considered. The data on their composition is used to identify the oil pollution sources, migration directions and rates of natural transformation.
