Alteration

  • (Local) Early Barren Stage Of Alteration By Fumarolic Or Acid-Hot Spring Activity Resulted In Intense Silicification, Wallrock Replacement By Jasper And Alteration Products Hematite, Diaspore, Alunite, Barite, Zunyite, Rutile, And Kaolin Minerals. Later Mineralizing Stage By Alkaline Or Neutral Solutions Deposited Ore And Gangue And Caused Micaceous Alteration (Sericite And Chlorite) And Calcite, Quartz, And Pyrite.
