| Abstract: | Two karst areas within Permian and Triassic carbonate rocks of the Codru Moma Mountains in the northwestern part of Romania
yield thermal waters. Major karst springs occur where groundwater flow is intercepted by hydraulic barriers, which also results
in the movement of water from deeper levels. At Moneasa, thermal groundwater rises along faults and fractures associated with
a thrust, and at Vascau Town, water rises along faults marginal to the Beius Basin. Geochemistry suggests that the thermal
component of the Moneasa groundwaters is derived from dolomites and that at least a proportion of the Vascau thermal waters
originates from deeply buried Permian sandstones.
