The uraniferous carbonaceous matters are found in some places in Japan where tertiary starata distribute on granite mass.
The Ouchi area, Miyagi Prefecture is one of the remarkable place for presence of uraniferous coal. The pajynological survey on the Ouchi coal has done systematically. According to the result, many miocene-type pollen and spores are found from the coal. Other paleobotanical data are obtainted by fossil leaf impressions, found from the strata overlied the coal seam. The paleoclimate during the deposition of the coal seam is supposed a warm-temperate.
