Summary¶Data from secondary fluid inclusions in barite and quartz occurring in strongly silicified lithologies (“Quarzite”) along the inter-Ordovician unconformity in SW Sardinia suggest that two distinct fluids are recorded in the mineral phases. (A), a high temperature (250–360 °C) – low salinity (0–6% NaCl equiv.) fluid, measured in quartz, (B), a high salinity (6–20% NaCl equiv.) – low temperature (<80–200 °C) fluid, measured in barite. Fluid (B), though less abundant than A, has also been… Expand

Pre-Variscan Ba Enrichment in Rocks Adjacent to the Sardic Unconformity (SW Sardinia, Italy)
Abstract Rocks from the Cabitza and Monte Argentu Fms, adjacent to the Sardic Unconformity (SU), are characterized by anomalously high concentrations of Ba. Very high Ba contents had been previouslyExpand
