This thermobarometry study employs calcite-dolomite solvus thermometry and thermodynamic pseudosections applied to marbles in the Făgăraș Unit, the uppermost unit of the Variscan metamorphic basement of the Alpine Supragetic units, Central Southern Carpathians. The marbles exhibit extensive relict granoblastic dolomitic bands and quartz inclusions, indicating formation through the metasomatic replacement of dolomite by calcite...
