The Pirén Alto Cu-(Zn) massive sulfide occurrence is a minor, noneconomic but genetically interesting ore type of the Paleozoic Coast Range ophiolite (Schira 1990) in south-central Chile. Manto-type massive Sulfides in the greenstone belt south of 38°S lat were first mentioned in reconnaissance studies (Alvarez 1970; Vergara 1970; Alvarez and Rivera 1970) and later outlined by various authors of the Universidad de Concepción (for reference see Alfaro and Collao this Vol.). The occurrence under consideration is one of the more important and less supergenely altered ones described therein.
