Outline of Final Research Achievements

Although hydrothermal petroleum had been considered to require a high temperature (higher than 250 degree C) for its generation, we sampled core sediments and reevaluated the generation condition at the actual site occurred the petroleum. As a result, petroleum generation from matured organic matter was confirmed at about 10 m depth below seafloor. At that depth significant intrusion of hydrothermal fluid was not observed and alteration clay mineral occurred at high temperature and hydrothermal clay minerals were rarely found. It suggests that the sediment at that depth dose not experience high temperature over 100 degree C. The temperature estimated by biomarker maturation indies is about 120 degree C , it is also comparable with the observation. In conclusion, it was confirmed that hydrothermal petroleum is generated at the temperature range (oil window) similar to conventional petroleum generation.
