Hallazgo de aleaciones metálicas de Cu-Zn (Grupo de la Zinccoperita) en el sistema epitermal Farallón Negro-Alto de la Blenda, provincia de Catamarca, Argentina

Findings and descriptions of metallic Cu-Zn alloys, such as the zinccopperite proposed in this work, are sparsely documented worldwide. The discovery of these compunds in various rocks from Farallón Negro-Alto de la Blenda (FN-AB) gold-silver mine represents an original contribution towards the depo...
