Abstract

The paper point out the deposits about the carbonate-hosted San Gregorio Colquijirca, as products of an epithermal high sulfidation system. Field, geochemical, and geochronological evidences suggest that the different ore types of the Colquijirca District are caused by a pulsed high sulfidation system subsequent to the emplacement of a diatreme volcanic complex. The first stage formed disseminated Au±Ag mineralization in areas affected by vuggy quartz alteration at Marcapunta. During a second stage, base metal mineralization replaced Eocene carbonate sediments from the Marcapunta diatreme to 2.5 km more to the north. San Gregorio and Colquijirca are to our knowledge the first "carbonate-hosted epithermal Zn-Pb high sulfidation deposit" recognized as such. The correct recognition of this ore type opens new exploration possibilities for base metal in high sulfidation systems affecting carbonate rocks.
