How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

- Sulfur isotope signature of pentlandite occurring in orogenic garnet-bearing peridotite by SIMS analyses. The aim of this short research period was to constrain the sulfur mobilization through the sub-continental lithospheric mantle wedge.
June 2019 - August 2019
The volatile transfer in subduction zones and the role of sulfate as a vector for the mobilization of oxidized components from down-going slabs remain hotly debated issues. Orogenic spinel and garnet peridotite lenses from the Ulten Zone (Eastern Alps, Italy), exhumed as part of felsic metamorphic terranes in continental collision zones, bear witne...
Carbonate-bearing wedge peridotites attest the mobilization of carbon (C) by slab fluids/melts circulating in a subduction setting. In general, COH fluids are thought to derive from the dehydration/partial melting of the crustal portions of slabs, especially during the exhumation of crust-mantle mélanges along continental subduction channels. In th...
Orogenic peridotites associated with high-grade felsic rocks occasionally occur in HP-UHP orogenic systems and offer the opportunity to provide quantitative constraints on slab-to-mantle mass transfer in these collisional settings. Ascending fluids and/or hydrous melts originating from the subducting continental lithosphere are assumed to enrich th...
