Geochemical data analysis and prediction of hydrocarbon accumulation in the territory of Rotmistrovka impact structure

Oil and gas potential of impact structures is a promising direction in exploration geology along with unconventional hydrocarbon sources like shale gas, tight gas and coal bed methane. Impact conditions contribute to redistribution and accumulation of hydrocarbons, create unique types of traps and provide migration of hydrocarbons from the source rocks. Industrial hydrocarbon reserves are proved in 12 of the 250 credible impact structures in the world. Now in Ukraine seven credible simple and complex impact structures are discovered. The area of Rotmistrovka Ukrainian crater is explored by the complex of structural-thermometric-atmogeochemical researchs. Article deals with the analysis of geochemical data of alkans, alkens, radon and thoron. It was established that the oil and gas potential of Rotmistrovka impact structure is associated with its perimeter parts which most likely related to its rims. Oil and gas formation within the studied area is influenced by both factors directly related to hydrocarbon migration and faulting factors that could be intensified by impact event. Features of appearances of oil and gas potential of Rotmistrivska impact structure are typical for other simple impact structures in the world.
