Outline of Final Research Achievements

(U-Th)/He chronology, which show the lowest closure temperature among chronological methods, is useful for analysis of geological history under low temperature such as formation processes of mountains. Thus, in-situ microanalyses of He in minerals are demanded. However, helium microanalyses are limited larger than a spatial resolution of several tens micrometers using conventional techniques, which is not smaller than a typical range of He recoil losses. Here, we develop sputtered neutral mass spectrometry to analyze He in natural zircon crystal. We have succeeded that the in-situ analysis can apply to measure He in zircon having more than 1 ppm concentrations with a spatial resolution of 7 μm which is much smaller than recoil loss range of alpha-particles.
