MINERÍA la mejor puerta de acceso al sector minero EDICIÓN 584 / MAYO 2026 32 Geología y Exploraciones Abstract Hydrothermal veinlets in porphyry copper deposits constitute an essential record of the magmatic-hydrothermal evolution associated with mineralization. This paper presents a technical systematization of their classification and evolutionary sequence (DQ → A → BMQ → B → C → D), based on a critical review of specialized literature and macroscopic observation of twenty representative samples from the collection of the Mineral Deposits Research Center (CIDM, Centro de Investigación de Depósitos Minerales) at the Universidad Nacional de Ingeniería (UNI). Published analytical data (mineralogy, physicochemical conditions, geochemistry, and instrumental techniques) obtained CLASIFICACIÓN Y EVOLUCIÓN DE VENILLAS HIDROTERMALES EN DEPÓSITOS TIPO PÓRFIDO DE COBRE
