Ground magnetic survey of Pan de Azúcar zone, Puna Jujeña (22°30′ S-66°00′ W)

The Pan de Azúcar Volcanic Complex crops out on the southern border of the Laguna Pozuelos basin (Puna Jujeña). It consists of several volcanic-dome centres of approximately 12 Ma age, formed by minor intrusives, lavas and pyroclastic rocks of dacitic composition. The volcanic complex hosts the Pan...

description The Pan de Azúcar Volcanic Complex crops out on the southern border of the Laguna Pozuelos basin (Puna Jujeña). It consists of several volcanic-dome centres of approximately 12 Ma age, formed by minor intrusives, lavas and pyroclastic rocks of dacitic composition. The volcanic complex hosts the Pan de Azúcar mine, which is one of the best known polymetallic ore deposits of the northern Puna. The interpretation of scismic lines located immediately to the north of Pan de Azúcar outcrops previously suggested the presence of a group of buried bodies, probably related to that volcanic complex. In order to confirm the existence of these buried intrusives, and to estimate their depths and sizes, a detailed ground magnetic survey was carried out in the Laguna de Pozuelos's area, immediately to the north of Pan de Azúcar. Modelling of the detected magnetic anomalies, suggests the existence of a body nearly 500 m in diameter, buried at a depth of approximately 200 m. Considering that the Pan de Azúcar Volcanic Complex is linked to economic ore mineralization, the results obtained in this study provide a set of valuable data to be taken into account for further mining exploration in the area.
