Abstract
Groundwater circuits in the main hydrothermal systems of Sardinia develop prevalently in the Paleozoic basement in the presence or absence of deep origin CO2. Another important aquifer is the Tertiary calcalkaline volcanics of Logudoro characterized by a high CO2 flow. The determination of selected trace elements in waters from these aquifers has led to the recognition of hydrogeochemical "markers' which appear to be more or less directly related to the lithological-geochemical characteristics of the reservoir rocksFile in questo prodotto:
