    1. Age and genesis of the White Pine stratiform copper mineralization, northern Michigan, USA, from paleomagnetism (pages 112–126)

      The world-class White Pine chalcocite deposit occurs at the base of the approximately 1081 ± 9 Ma Nonesuch shale. Current genetic models posit that the mineralization formed within approximately 3 Myr of shale deposition. Paleomagnetic analysis dates epigenetic ore genesis at 1063 ± 8 Ma, after conversion of the underlying primary Copper Harbor clastics to red beds, by hydrothermal fluids from the adjacent southeastern Keweenawan rift margin.

    2. Fluid channeling along thrust zones: the Lagonegro case history, southern Apennines, Italy (pages 140–158)

      Fluid inclusions and geochemical analyses were performed on syntectonic zebra-dolomites and syntectonic calcite and quartz veins from the Triassic-Jurassic Lagonegro Basin succession (southern Apennines, Italy) in order to characterize the different parent fluids, channelled along a major, out of sequence thrust zone. A close match between the O-Sr-isotopic signatures of dolomites and of calcite veins from the tectonic mélange suggests that dolomitizing fluids were squeezed out from the tectonic mélange occurring at the base of the Lagonegro units and in which the out of sequence thrust is soled.

    3. Diagenesis versus hydrothermalism and fluid–rock interaction within the Tuscan Nappe of the Monte Amiata CO2-rich geothermal area (Italy) (pages 159–179)

      Past fluid circulations within Monte Amiata geothermal region were characterized from mineralized veins: FLUID-1 precipitated syn-tectonic burial calcite; FLUID-2 related to a fossil geothermal system, fed by meteoric fluids, enriched in CO2 of deep origin and geochemically buffered by interaction with sub-surface rocks; FLUID-3 records a meteoric signature similar to other reservoirs of southern Tuscany. The peculiarity of FLUID-2 system suggests past compartmentalization of the Monte Amiata geothermal reservoirs. Vein host-rocks were geochemically reset after interaction with the CO2-rich FLUID-2.

    4. Diagenetic evolution of a fractured evaporite deposit (Vilobí Gypsum Unit, Miocene, NE Spain) (pages 180–193)

      The present study evidenced the effects of early post-rift deformation stages in an evaporite unit and their linkage to basin scale events. It has been established the parental fluids of the fracture infillings of the Vilobí Gypsum Unit and their evolution during the different precipitation events. Geochemical data reveals chemical recycling processes linked to fluid flow along the fractures dissolving the closest sulphates. Thus, each successive infilling event resulted from recycling of the preexisting gypsum.
