Abstract: Serpierite Ca(Cu,Zn)4(OH)6(SO4)23H2O occurs as small blue crusts covering millimeter-size gypsum crystals on the ceiling of a small mining gallery in Trestia-Băiţa area, Metaliferi Mountains. X-ray diffraction, optical, and scanning electron microscope with EDX and Raman spectroscopy have been used to identify the mineral. Genetically, serpierite derived from weathering of primary hydrothermal cooper and lead deposits. This is the first reported occurrence of serpierite in Romania. | |||||||
