Upper Quaternary carbonates and the conditions of their formation are attractive for current climate studies, as they represent an almost inexhaustible source of data on paleoenvironment and paleoclimate. In this work we describe the Tarague limestone in detail. The carbonate was first described in the 1990s, but it has never been petrologically characterized. Thinsections of the Tarague limestone were examined under an optical microscope and the results were compared with schemes for determining recent diagenetic environments. We identified many generations of cements of marine or freshwater phreatic and vadose diagenetic environments, which indicate dynamic changes in seawater during the last interglacial period.
