Abstract
the chemical composition of several specimens of the Mineralogical Museum of Florence was established usign optical and SEM microscopy and WDS microanalysis (EPMA). THe speciemens are attributed to chalcocite, djurleite, anilite on the basis of theier Cu/S ratio. Fe is both minor substituent for Cu and trace element, which allows the correct attribution of digenite Finally, Ag-bearing varieties of chalcocite, djurleite, and digenite are identified with Ag-content ranging up to 0.009 atoms per formula unit.File in questo prodotto:
