Shimooka, Kazuya*; Ogita, Yasuhiro  ; Saito, Satoshi*

We discovered a new poikilitic texture in the felsic rocks of Kajishima, Shisakajima, northeastern Ehime Prefecture, Japan. In this presentation, we carried out chemical compositions of the poikilitic texture, and whole-rock chemical compositions of the felsic rocks. Based on the results, we discussed the formation process of felsic rocks distribute on Kajishima.
