Resumen de Estudio de algunos indicios cupríferos en la Depresión Geológica del Ebro (Bages, Cataluña)
This short communication is based on the research developed on three cupriferous traces in the Catalonian area of Bages. These three traces are found among the tertiary materials of the Artés formation belonging to the Ebro Geological depression in the area corresponding to the Central Depression. These three cases are about «stratabound» mineralisations, whose origin are as a consequences of a precipitation of Cu, in sulphide form, carried by continental waters (in the shape of soluble sulphides). Later, these sulphides formed in reductant environments get oxidized in presence of calcite, becoming then carbonates
