2022年2月2日 Hydrothermal gangue calcite is common and is often associated with barite, quartz and ankerite. Ankerite (up to 2 mm in size) displays euhedral crystals and occurs also as an open space-filling mineral. Gangue quartz (Qtz II) shows prismatic euhedral crystals 0.1 to 1.5 mm long, often associated with calcite, ankerite and siderite.
