抄録
Carbonaceous materials in Paleozoic shales from the Kasuga area, Gifu, Japan, which were subjected to contact metamorphism during the Jurassic, have been studied for the X-ray diffraction, elemental composition, and hydrogen and carbon isotopic compositions. Results on the X-ray diffraction and elemental analyses clearly indicate that the degree of graphitization of the carbonaceous materials decreases with distance from the contact. Within the metamorphic zone, δ13C values for the materials decerase with distance from the contact, from -18‰ to -31‰. The trend of δD values for the carbonaceous materials is similar to that of δ13C values. The δD values are rather constant at the level of -130‰ outside the metamorphic zone and increase up to -95‰ within the metamorphic zone. The results on the isotopic compositions suggest that some volatiles depleted in D and 13C have been removed from the carbonaceous materials during the contact metamorphism.
