The formation of Parzan fluorite-lead «extension-type» vein (Spanish Central Pyrenees) is related to the post-Hercynian hydrothermal activity widespread not only in the Pyrenees but in Western Europe as well. The lode was later strongly deformed du

We applied the hard and soft acid-base (HSAB) model (Xu and Harsh 1990a, 1990b) to bivalent cation exchange on a purified Ca-montmorillonite. As a result, a satisfactory model is proposed to describe the gradual selectivity of exchange with Ca for 4

This paper presents preliminary results on the fixation of Zn 2+ and Pb 2+ by a purified Wyoming Ca-montmorillonite, in different experimental conditions: variable (3 · 10 −5 I −2 M or constant ( I = 3.10 −2 M) low ionic strength solution, and

In the basin of southeastern France, (sub-Alpine range), circulation of palaeofluids relates to the geodynamic evolution of the western Tethyan margin. Alpine chain build-up from the Triassic to Present. Recent reconstructions allow distinction of tw

The origin and evolution of different ore deposits grouped in the same district are often complex and may involve inheritance from crustal or mantle geochemical anomalies, remobilization of former ore deposits and a polyphase hydrothermal history. Lo

Large thenardite crystals have been sampled at New Agorgott, in the Taoudenni area of northern Mali. They are still in equilibrium with a pressurized NaCl saturated brine capped by a halite layer. Clays located about 1 m above the thenardite occurren
