Outline of Final Research Achievements

Effective boron separation methods (micro-sublimation and mini-column methods) from geological materials are developed. In addition, laser ablation-multiple-collector ICP mass spectrometer (LA-MC-ICP-MS) method is developed for in situ analyses of boron isotope. Repeated analyses of geological standard reference materials yielded high precision and accurate results. Annual-scale boron isotopic analyses for coral skeleton from Guam Island provide an evidence for ocean acidification in tropic Pacific seawater. Boron isotopic profile analyses for interstitial water in sediments at active hydrothermal area in Okinawa Trough demonstrate that boron isotope is an effective tracer for investigation of sub-bottom circulation pattern of hydrothermal fluids. Boron isotopic analyses by LA-MC-ICP-MS on tourmalines from Yamaguchi Prefecture indicate that fluids related to the formation of tourmaline were strongly linked to host granitic magma.
