Petrology of titanian clinohumite and olivine at the high-pressure breakdown of antigorite serpentinite to chlorite harzburgite (Almirez Massif, S. Spain)

Evolution of Fe redox state in serpentine during subduction

“…Numerous studies have shown that most of the major elements, in particular iron, are immobile during the serpentinization processes at the oceanic ridge (Andreani et al, 2013;Godard et al, 2008;Mével, 2003;Paulick et al, 2006) and during prograde metamorphism in subduction zones (Debret et al, 2013a(Debret et al, , 2013bGarrido et al, 2005;López Sánchez-Vizcaíno et al, 2005). In agreement with these previous results, no significant change of Fe content is observed in our serpentinites samples during prograde metamorphism (Table 1).…”

Subduction- and exhumation-related structures preserved in metaserpentinites and associated metasediments from the Nevado–Filábride Complex (Betic Cordillera, SE Spain)

“…1) The layers of metamorphic diopside + Ti-Clinohumite (López Sánchez-Vizcaíno et al, 2005) show an internal planar-linear fabric coherent with the S 1 in the Atg-serpentinite.…”

Magmatic diversity of western Mexico as a function of metamorphic transformations in the subducted oceanic plate

“…Ti-clinohumite has also been regarded as potential sink for HFSE in hydrous mantle lithologies for a wide range of conditions Ló pez Sánchez-Vizcaíno et al, 2005). Nevertheless, thermal decomposition of Ticlinohumite mostly occurs well below the wet peridotite solidus, and has never been identified as a residual phase upon partial melting (Stalder and Ulmer, 2001).…”
