AB Several Pb-Cu-Zn orebodies of different size and origin occur in Paleozoic materials from the D em andam as8if d /at has been m a in ly deformed by the Hercynian orogeny. Most of the here studied deposits arevein type, except Carmina mine that may account for a sedex type one. All of them are hosted by Upper Cambrian shales and sandstones. The isotopic and geologic features of these orebodies suggest that therehave been different ages of xliineralization, and that hydrothermal solutions came from a similar sourcerelated to the Paleozoic sedimentary sequence
