Isolated, but transnational: the glocal nature of Waldensian ethnobotany, Western Alps, NW Italy
BACKGROUND An ethnobotanical field study on the traditional uses of wild plants for food as well as medicinal and veterinary plants was conducted in four Waldensian valleys (Chisone, Germanasca, Angrogna, and Pellice) in the Western Alps, Piedmont, NW Italy. Waldensians represent a religious Protestant Christian minority that originated in France and spread around 1,170 AD to the Italian side o...
متن کاملNew isotopic constraints on age and magma genesis of an embryonic oceanic crust: The Chenaillet Ophiolite in the Western Alps
The Chenaillet Ophiolite is one of the best-preserved remnants of the Piemont-Liguria oceanic basin, a branch of the Central Atlantic that opened during the separation of Adria/Africa from Europe. Despite numerous studies of structure, petrology, geochemistry and isotope geochronology, the timing and genesis of various magmatic rocks within the Chenaillet Ophiolite are still controversial. We p...
متن کاملPrograde P–T evolution of a lawsonite eclogite from the Monviso metaophiolite (Western Alps): dehydration and redox reactions during subduction of oceanic FeTi-oxide gabbro
Lawsonite eclogites represent fossil records of processes occurring during subduction of cold and fast-subducting slabs, and provide the opportunity to investigate the thermal and metamorphic evolution of palaeosubduction zones. Occurrences of lawsonite eclogites are rare because lawsonite is often replaced during exhumation. We report here, for the first time, the occurrence of a lawsonite ecl...
متن کاملU-Pb zircon constraints on obduction initiation of the Unst Ophiolite: an oceanic core
7 The Unst Ophiolite is the best exposed of a chain of early Ordovician ophiolites in the 8 Scottish Caledonides and is widely regarded as having formed in a supra-subduction zone 9 setting within the Iapetus Ocean. Reinterpretation of sheeted dykes suggests that it formed 10 as an oceanic core complex, presumably during subduction roll-back immediately prior to 11 obduction onto the Laurentian...
متن کاملHighly permeable and layered Jurassic oceanic crust in the western Pacific
Bulk permeability was determined from drillstring packer measurements in ODP Hole 801C in Jurassic oceanic crust in the western Pacific. The values average 8 x 10 -14 m 2 over 93 m of open hole, or 4 X 10 -13 m 2 if the permeable interval is confined to an 18 m thick hydrothermal zone within oceanic basement. These values are about 1-10 times higher than those reported for the upper sections of...
