Rare earth element geochemistry and fluid inclusion study of akcakent fluorite veins in central anatolian massif of Turkey

Abstract EN

Fluorite veins of Akcakent (Central Turkey) occur in the fractures and fissures of the Upper Cretaceous-Paleocene syenites, and gabbros.

Their geological setting, rare earth element geochemistry, and fluid inclusion data show that the fluorite is of hydrothermal origin, and has crystallized within a 140-180°C temperature range, probably from a mixture of magmatic and meteoric fluids.

The fluorite deposition in the various veins was coeval and occurred under homogenous conditions.
