- Abstract
- The present article illustrates a straightforward case of hydrothermal dolomitization,
affecting Jurassic platform limestones of the Provenc¸al and Subbrianc¸onnais Domains
(Maritime Alps, North-Western Italy). Dolomitized bodies are randomly distributed
within the host limestone, and are commonly associated with dolomite vein networks and
tabular bodies of dolomite-cemented breccias discordant with respect to bedding. Main
dolomite types are a finely to medium-crystalline replacive dolomite and a coarsely-
crystalline saddle dolomite occurring both as replacive and as cement. Stratigraphic
constraints indicate that dolomitization occurred during the Cretaceous, in a shallow
burial context, and was due to the circulation of hot fluids (temperature about 200 8C, as
indicated by fluid inclusion microthermometry) through faults and related fracture
networks. Hydrothermal dolomitization therefore indirectly documents a Cretaceous fault
activity in the Maritime Alps segment of the European Tethyan passive margin. (literal)
