Two metamorphic belts in northern Venezuela were metamorphosed at high pressure–low-temperature conditions in a Cretaceous subduction zone. Both belts, the Cordillera de la Costa and Villa de Cura, contain several generations of quartz ± calcite veins that formed during two stages of orogenic development. The first stage encompasses five generations of ductile deformation structures. This was followed by at least two generations of brittle deformation. Quartz veins related to the different deformations contain several types of fluid inclusions. Most are two-phase with an aqueous NaCl-H₂O solution. Texturally early fluid inclusions show a wide range of homogenization temperatures with...
