“…Rodingites have been reported in ophiolites from various tectonic settings, mostly from the seafloor and rarely from the subduction zones (Koutsovitis et al 2013). Honnorez and Kirst (1975) reported rodingites from the mid-Atlantic fracture zones together with serpentinized ultramafics and fresh and metamorphosed basalts and gabbros.…”

“…Rodingites are not petrologically significant because their typical mineral assemblage of diopside + grossular provides little information about their formation conditions, such as pressure and temperature. However, rodingites have attracted attention of petrologists because of their role in fluid-rock interaction in oceanic lithospheres (Austrheim and Prestvik 2008;Frost et al 2008;Bach and Klein 2009) and subduction zone settings (Koutsovitis et al 2013;Li et al 2014). Rodingitization commonly occurs in Ca-rich and Si-deficient environments, although each rodingite has a unique formation setting.…”

“…Crustal contamination processes most likely did not take place due to the tholeiitic affinity of the studied mafic rocks. On the other hand, the types of hydrogarnet and vesuvianite crystals found within the rodingites are indicative for the involvement of subduction-related fluids during the formation of the rodingites (Koutsovitis et al, 2013). In addition, the chemistry of spinels in serpentinites (TiO2=0.14-0.25 wt.%, Al2O3=35.1-35.21 wt.%, Cr#=37.38-38.87), shows that their harzburgitic protoliths plausibly resemble back-arc basin peridotites (Kamenetsky et al, 2001).…”

“…Li et al (2008) explains the formation of hydrogarnet with clinopyroxene and water participation in the reaction with plagioclase, whereas Cr-bearing hydrogarnets formation is related with Cr release from serpentinites (Li et al, 2004). The vesuvianite was most likely formed in very low CO2 conditions with water rich fluids, at 300-400 ο C (Li et al, 2004, Hatzipanagiotou et al, 2003, Li et al, 2008, Koutsovitis et al, 2013. Nevertheless, in a lower T stage and during the ophicalcite formation the chemistry of pore waters were enriched in CO2.…”
