Critical metals in sphalerites from Belgian MVT deposits

peer reviewed ; Belgium hosts a series of well documented low temperature, carbonate hosted, lead-zinc veins and lenses clearly categorized as MVT deposits. This paper revisits the distribution of trace elements in sphalerites from Belgian deposits with a special focus on Ge, Ga and In. By comparing with a database of worldwide deposits, this paper shows that Belgian sphalerites do not display a classical substitution pattern involving Cu+. Instead, multivariate analysis points towards similarities with the Tres Marias deposit in Mexico, although the explanation of coupled substitution with Fe... Mehr ...
