Four streams flowing in the Iglesiente and Arburese mine districts (SW Sardinia, Italy),
exploited for zinc (Zn) and lead (Pb) extraction from sulphides and secondary non-sulphide
mineralization (calamine ores), have been studied combining investigations from the
macroscale (hydrologic tracer techniques) to the microscale (X-ray powder diffraction,
scanning electron microscopy, X-ray absorption spectroscopy). In the investigated area,
concerns arise from release of metals to water during weathering of ore minerals and mine …
