The extensive Casapalca veins cut Tertiary volcanic rocks and red beds near the crest of the Peruvian Andes. The veins correspond to a fracture system which probably formed during one period of tectonic activity. Paragenetic studies identify four stages of mineralization without obvious time breaks characterized by (1) sphalerite-galena-pyrite, (2) chalcopyrite-pyrite-sphalerite, (3) tetrahedrite, and (4) quartz-carbonates. The tetrahedrite is the main source of silver, and its paragenetic… CONTINUE READING
