Gangue minerals SpringerLink
They are commonly silicates, carbonates, or fluorides, more rarely sulfides. The gangue minerals of ore deposits formed at high temperatures differ from those deposited at lower temperatures. The principal ones are as follows: epithermal: adularia, alunite , calcite , chalcedony, fluorite , opal, quartz.
