| Outline of Final Research Achievements |
Trace element contents in fluid inclusions from a miarolitic quartz at the M-type Tanzawa granite, Kanagawa Prefecture, Japan, were determined by particle-induced X-ray emission (PIXE) to elucidate chemical features and behaviors of hydrothermal fluids derived from the M-type granite in the island arc. Polyphase and two-phase fluid inclusions in the quartz showed higher concentrations of Cu, Ti, and Mn (or Fe) and extremely lower contents of Ge and Sr, compared with those from the Kofu granite, Yamanashi, Japan, which is an I-type Miocene granite.
