Fluorite from the veins of El Hammam orefield (Central Morocco) show hypersaline fluid inclusions, rich in NaCl and CaCl2. In this orefield, a strong zonality is focussed on a peraluminous granite apex. The study of fluid inclusions and REE suggests a centrifugal deposition. In the core, fluorite and carbonates are deposited by decreasing temperature brines (200°-100°) and reflect the circulation of hydrothermal solutions followed by more superficial fluids. On the edge, the fluorite veins and stockwerks present lower deposition temperatures and more obviously feldspathic REE patterns. This orefield is thus very similar to that of the Tarn area (France).Les fluorines des filons du district d'El Hammam (Maroc Central) montrent des inclusions...
