67.含水加熱による人口石炭の石炭岩石学的変化

抄録

8 samples from resent plant materials and pests were heated with water under various temperatures. Product materials, artificial coals, have been measured their vitrinite reflectance (Ro) and observed their petrographic texture. From the results of Ro, Ro of woody parts increase linearly under all temperature, but that of leaves and pests are not liner and changed around Ro=0.6 which is recognized the beginning of oil formation. On petrographically observations, it assumed that one of important factors for coal characteristics is under the condition during a few years after depositions.
