Zusammenfassung
This paper summarizes the main geological and metallogenic features of the Pb-Zn ore bodies of «San Juan» and «San Carlos» in Ibiza (Balearic Islands), located in Lias-Dogger dolostones; «Loma Chara», near Olvega (Soria), in Oxfordian limestones; and «San Rafael 2?», in the vicinity La Unión (Murcia), in Triassic dolomites. The Soria and Ibiza deposits correspond to a concentration of Pb and Ba in a karst developed on a previously existing stratabound BGPC mineralization. On the contrary, the Murcia ore body was originated by hidrothermal activity which gave place to the BGPC ores of the Sierra de Cartagena, but following have a karst developed either by weathering processes or the own hydrothermal solutions.
