Abstract

Around the Hakata Bay, some granodiorite intrusions are recognized with several granite bodies.  Their constituent minerals were analyzed about their compositions for estimating pressure-temperature conditions.   As the results, the temperature and pressure for the simultaneous Itoshima granodiorite and Kitasaki granodiorite estimate around 700 ˚C and 1.6~2.7 kbar, and 730 ˚C and 2.5~3.6 kbar each.   The Shikanoshima granodiorite shows P-T condition with 1.3~2.7 kbar and 650~690 ˚C.
