Abstract The paleosalinity of water from which the gypsum precipitated during Messinian salinity crisis is a controversial issue. Recent microthermometry studies on primary fluid inclusions in provided very low values not compatible with precipitation seawater, and suggested strong mixing between seawater nonmarine waters enriched calcium sulfate. We applied new microthermometric protocol cryst...

The brines in the chotts and sebkhas of Algerian Low Sahara are solutions characterized by a salinity that far exceeds waters sea (120 to 440 g/l). Over past three decades, these lacustrine systems (chotts sebkhas) have become an estuary for all types urban discharge; this situation highlights environmental impact discharges on systems. chemical analysis showed average concentration certain tra...

Triassic evaporites have a very particular location in the Pyrenees, close to detachment areas between basement and sedimentary cover, constitute an enormous chlorine potentially brine reservoir. During two successive deformation cycles related successively Cretaceous rifting convergence during early Cenozoic, brines were expulsed implied fault activity, breccia formation fluid–rock interaction...
