AlterationSix types of hydrothermal alteration have been differentiated (Yesilyurt, 1996). Carbonate-quartz alteration occurs in a peripheral zone of the metasomatic minerlization at the mine. An actinolite-pyrrhotite assemblage occurs adjacent to the gold mineralization. Potassium silicate alteration occurs adjacent to the porphyry intrusions and consists mainly of alkali feldspar, biotite, tourmaline, allanite, and quartz. A chlorite-sericite-carbonate alteration assemblage occurs sporadically in the area. The most widespread type of alteration at Liberty Bell is a quartz-sericite-clay assemblage. Supergene alteration and weathering overprint all of the hydrothermal assemblages.
