Microscopic Raman analyses of daughter minerals in polyphase fluid inclusions of quartz crystals

Abstract

Daugter minerals in polyphase inclusions of quartz crystals from a miarolitic cavity and quartz veins at the Tsushima granite, Japan, were analyzed with Raman microscopy to examine chemistries of hydrothermal fluids from the Miocene granite body. Small crystals of siderite, ferropyrosmalite, and iron hydroxide-like phase were detected in the inclusions.
