Zunyite associated with alunite and pyrophyllite from Mi Vida ore deposit, Catamarca Province: mineralogical characteristics and paragenetic significance
In Mi Vida ore deposit (Cu-Mo), a small area within the Carudo Breccia (an Upper Miocene diatreme with abundant metamorphic fragments) was affected by an episode of advanced argillic alteration characterized by the quartz-pyrophyllite-alunite-zunyite-rutile association. The conditions proposed for t...
