The wall-rocks of the Bridge River gold quartz veins have been hydrothermally altered by warm alkaline mineralizing solutions, containing carbon dioxide, potassium, sulphur and arsenic, which has brought about the partial replacement of the primary constituents of the wall-rocks by such secondary minerals as carbonates, sericite, talc, epidote, chlorite, albite, quartz, pyrite and arsenopyrlte. The dominant process of the alteration has been that of carbonization with up to 75 per cent of the rocks being altered to carbonate. In the more acidic types of wall-rock the carbonate is principally in the form of calcite, while in the more basic varieties, an ankeritic or dolomitic type of carbonate has been the dominant variety developed.
