Photomicrographs of fluid inclusion assemblages from different hydrothermal stages in the Xiejiagou gold deposit. (a) Primary type Ιa FIs in early-stage quartz; (b) type Ιa FIs coexist with type ΙΙ FIs in early-stage quartz; (c) type Ι FIs coexist with type ΙΙ and type ΙΙΙa FIs in middle-stage quartz; (d) type Ιb FIs coexist with type ΙΙ FIs in middle-stage quartz; (e) type Ιa FIs coexist with type ΙΙΙa FIs in middle-stage quartz; (f) primary type ΙΙΙa and ΙΙΙb FIs in middle-stage quartz; (g) type ΙΙΙa and ΙΙΙc FIs in late-stage quartz.
