Resumen:
A petrographic study carried out on two mineralized breccia bodies outcropping at Quebrada Blanca, in the southeastern end of Sierra de La Huerta, San Juan province, is presented. Based on their textural and compositional features, and the relationship with a rhyolitic intrusive body, these breccias are classified as hypabisal breccia pipes or push-up intrusive breccias. Both breccia outcrops show disseminated sulfide mineralization (mostly pyrite and minor chalcopyrite and marcasite).
