The Pingüino deposit represents an atypical epithermal occurrence in the low sulfidation (LS) epithermal Deseado Massif metallogenic province. This deposit is characterized by the presence of two different mineralization styles, massive suiphide veins with high contents of Zn, Pb, Ag, In. Cd, Au, As, Cu, Sn, W, Bi, and quartz veins with anomalous values of Ag, Au and base metais. The quariz veins present banded quartr associated with reddish to brownish carbonates, which were studied by microscopy petrography and X-ray diffraction. The present contribution describes the first report of rhodochrosite in epithermal veins of the Deseado Massif. The presence of rhodochrosite in this mineralization could be indicating an affinity with intermediate sulfidation (IS) epithermal deposits.
