日本西南部内陆带最外侧的旧良屋花岗岩侵位于中白垩纪，位于欧亚大陆东缘，日本海尚未打开。Ryoke带是亚洲太平洋白垩纪-古近纪长英质岩浆带的一个长段。较老的Ryoke花岗岩类代表了其最初的岩浆活动，与当时欧亚板块下方的海洋板块俯冲有关。它们的岩浆是在俯冲体制下，在Ryoke带下方的下地壳到中地壳中生成的。它们在Ryoke区域变质作用期间侵位并转化为正片麻岩。
Abstract The emplacement of the Older Ryoke granitoids took place in the Mid-Cretaceous Period in the outermost side of the Inner Zone of southwest Japan, which was located at the eastern margin of the Eurasian Continent before the opening of the Japan Sea. The Ryoke Belt constitutes a long segment of the Cretaceous to Palaeogene felsic magmatic belt of Pacific Asia. The Older Ryoke granitoids represent its initial magmatism, related to the subduction of an oceanic plate underneath the Eurasian plate in that time. Their magmas were generated in the lower to middle crust beneath the Ryoke Belt in the subduction regime. They were emplaced during the Ryoke regional metamorphism and converted to orthogneisses.
