Petroleum Geology and Exploration Potential of oft-com:office:smarttags" />Volga-Ural Basin: One Typical Foreland Basin
详细信息   
摘要
 The Volga-Ural Basin is a typical foreland basin in the eastern margin of the Eastern Europe Platform.Subsidence continued from Riphean of pre-Cambrian to Quaternary of Cenozoic.The assemblages of source rock,reservoir and seal exist in the marine facies carbonate rocks of the middle and upper Paleozoic,resulting in giant petroliferous region which has great potential for petroleum exploration.The tectonic evolution of the basin can be divided into four stages. Studies show that the basin has underwent a complete “Wilson Circle” from continent rift to continent collision,and is regarded as a typical giant foreland basin.Biological carbonate rocks generated during the passive margin stage contributed to hydrocarbon generation.
