Abstract
Tsushima granite and the related rocks, southwestern Japan, are known for abundant aqueous polyphase inclusions with large daughter crystals. We non-destructively analyzed the polyphase fluid inclusions in quartz crystals from a miarolitic cavitie at the Tsushima granite with synchrotron radiation XCT and Raman microspectroscopy. The results show presence of daughter crystals of halite, sylvite, saltonseaite siderite, and Fe-OH mineral in the inclusions. Then, after we peeled the surface of mother phase, quartz, polyphase inclusions were directly observed and analyzed with SEM-EDS.
