Petroleum-like hydrocarbons have been occurred commonly associated with hydrothermal activity. The hydrocarbons, "hydrothermal petroleum", were generated by the interaction between a hot hydrothermal fluid and sedimentary organic matter in a deposit distributed around the hydrothermal systems such as the continental margin and volcanic systems in land areas. Until recently, the occurrences of a significant amount of the petroleum have been discovered in seven marine hydrothermal fields located on seafloor spreading axes and the submarine volcanoes of island-arcs. However, the occurrence of petroleum has not been reported from hydrothermal fields associated with back-arc rifting and spreading zone, except the King George Basin in Antarctica. Seafloor hydrothermal systems located in the back -arc basin are suitable for occurrence of a large amount of hydrothermal petroleum, because the back-arc basin is developed near the continent and expected to be covered with thick sediment. There are many hydrothermal fields in Okinawa Trough, although the occurrence of the hydrothermal petroleum has not been reported. In this paper, origins of oil and gas reserved in the volcanic rocks of the Green Tuff region in the northeast Japan were discussed, and the possibile occurrence of hydrothermal petroleum from such region is suggested. The Green Tuff terrene has been known as one of the active areas of submarine volcanisms, and thus hydrothermal activity had enhanced the maturation and improved the potential of the reservoir rocks. Further studies are necessary for investigation and identification of economically valid hydrothermal petroleum, which was generated during ancient age and reserved in the geological systems.
