Geological structures of the Shimanto Belt in southwestern Kyusyu and Tokunoshima Island have been investigated. In the Hokusatsu district, layers of basaltic lava, chert and mudstone form imbricate structure. The Yaseo area in the Satsuma Peninsula carries one of the serpentinite occurrences in the Shimanto Belt. Two majorserpentinite bodies are exposed in the areas extending about 100 x 50 m and 200 x 70 m.These overlie west-dipping layers of sandstone and mudstone with subhorizontal boundaries.In the Choyasan area of the Nansatsu district, layers of mudstone and sandstone generally dip west with westerly younging. Geology of the central part of Tokunoshima Island is composed of pelitic-psammitic schsits, granitic intrusive rocks and sporadic serpentinite. Lenticular bodies of serpentinite dipping northwest in low angles are distributed in the pelitic schist. Dark-shaded veins with up to 20 cm thick appearin the pelitic and psammitic schists at the mouth of Akirigami River in western Tokunoshima. Fragments of the country rocks in variable sizes and fine-grained particles fill the veins.

已经研究了西南京西岛和托库尼岛岛的Shimanto带的地质结构。在河谷区，玄武岩熔岩，切尔特和泥岩形式的结构。 Satsuma半岛中的Yaseo区域携带Shimanto带中的一种蛇纹石发生。在延伸约100 x 50 m和200 x 70的区域暴露了两个大满贯的尸体，这些覆盖了这些覆盖的砂岩和泥岩层，并带有亚果子边界。在南萨苏州地区的Choyasan地区，泥岩和砂岩层通常浸入西风。 Tokunoshima岛中央部分的地质是由毛刺岩石，花岗岩侵入性岩石和零星的蛇纹石组成的。低角度向西北浸入西北浸入的凸耳体分布在毛状片岩中。深色阴影的静脉最高为20厘米，厚度为Pelitic和Psammitic片岩，位于西托岛西部的Akirigami河口。该国岩石的碎片大小和细粒颗粒充满了静脉。
