[SGL33-P11] Structural position of the Akiyoshi Limestone in the Permian accretionary complex of the Akiyoshi Belt, Southwest Japan
Keywords:Akiyoshi, Limestone, Permian, accretionary complex
The most probable case is the limestone part on the seamount offscraping in the deep part of the accretionary wedge. After the offscraping, the limestone fragment moved upward, and appeared at the outer forearc high. The limestone fragment collapses and accumulates into forearc basin and/or trench slope basin. The purpose of this study is to reveal the accretionary process of the Akiyoshi limestone, which was offscraped from the top of the seamount and incorporated into the accretionary prism in the Permian period. Present analog of the Permian accretionary complex of the Akiyoshi Belt is the accretionary prism formed along the Java Trench near the Sulawesi Island, western Indonesia. In the presentation, new tectonic model of Akiyoshi limestone is proposed using analog of the Java accretionary wedge.
