Danube basin originated in Lower Miocene as pull-apart basin (N part). During Middle Miocene the basin extended to the S and during late Miocene and Pliocene the subsidence was of thermal origin. Basin is mostly filled by clastics and large volcanic bodies are buried in the basin too. The mean temperature gradient reaches 39.1 °C/km, average value of heat flow density is 72±6m Wm-2. Seven small methane gas fields were discovered in NW part of basin and several gas and/or condensate shows are known in S. part of basin. According to an approximation of the thermal maturity of organic matter in the basin using the Lopatin model the oil and gas windows should be in the depth below 3000 m. Source rocks can be marine and swamp deposits.
