Geological characterization and microthermometry of the Los Mellizos ore deposit (37°20'LS, 70°30'LO), Neuquén Province

The aim of this paper is the characterization of a copper mineralization located in the Agrio fold and thrust belt (20 km to the west of Chos Malal, Neuquén Province). Analyzing the structures and textures that could be researched in the mineralizations and the bed rock, we deduced a hydrothermal or...

Analyzing the structures and textures that could be researched in the mineralizations and the bed rock, we deduced a hydrothermal origin for the deposit.
