Abstract

This paper describes the cooperative project which will consist of chronological research of the volcanic activities in the Luzon Island in the Philippines by thermoluminescence (TL) and radiocarbon (^<14>C) methods. Preliminary chronological studies on Irosin caldera and Mayon Volcano revealed that the Irosin caldera was formed at 41 kyr cal BP and that Mayon Volcano started its eruptive activity at 20 kyr cal BP. We also conducted preliminary investigations at Pinatubo Volcano, Laguna and Taal calderas. Although many ^<14>C dates were already reported from the Pinatubo Volcano, we plan to apply not only ^<14>C dating but also TL dating methods to the rocks of this volcano. TL dating is applicable especially to volcanic rocks in Pinatubo Volcano and Irosin caldera, because they include quartz phenocrysts. Our goal is to establish the tephrochronological framework of a wide spectrum of deposits: from widespread tephra deposits of large caldera volcanoes to the monogenetic volcanoes in the Luzon Island,
