Geologic Significance of Granitic Fragment Found from Pumice flow of 1883 Eruption at the Krakatau Grup Indonesia

---

Pumice flow of the 1883 Krakatau eruption occurs It at Small Rakata, Rakata and Sertung Islands, those which roughly correspond to the wall of Krakatau caldera, Indonesia. significantly differs in both mineral and chemical compositions against any other volcanic rock or ejecta of the Krakatau Group, those of which belong to Miyashiro's (1974) tholeiitic series. Meanwhile, lithic fragments of granitic rock, ranging in modal composition from quartz monzonite to quartz monzodiorite, those of which were found from the pumice flow are, in both mineral and chemical compositions, similar to west Malayan granitic rocks represented by biotite quartz monzonite which occurs as the dominant rock type in west Malay Peninsula (Hamilton, 1979). None of granitic rock occurs throughout over the Krakatau
