• 要約等: application/pdf; In Tohoku District, several valuable earthy graphite deposits are found distributed as shown in Table 1 and Fig.1. All deposits are graphite beds and geological ages of their country rocks are presumed to be between lower Carboniferous and upper Jurassic as seen in Table 1. Intrusions of plutonic or dyke rocks and geological disturdances are observed in every deposits. In the deposits of Otomo and Hashinoue, contact minerals such as sillimanite, garnet, wollastonite, tremolite, tourmaline and bictite are found as the results of the intrusion of granodiorite. In the deposits of Takase, Takenohara and Miyagi, cataclastic ores are seen as the results of dynamic metamorphism and weak thermal effects by the intrusion of granodiorite are also observed. In the deposits of Nakamura, Ohara and Miwa, calcite veinlets and pyrite disseminations are observed as the results of hydrothermal metamorphism attended by the intrusions of porphyritic rocks. Carbon contents of ores are mostly about 30%, but in special case reached over 75%. Several t xtures of ores are observed as shown in Fig.2. It is concluded that earthy graphites in Tohoku District were derived from sedimentary carbonic matters by the thermal, dynamic or regional metamorphisms.; 紀要類(bulletin); 1777901 bytes
