“…Alternatively, by the time peridotite begins to melt, pyroxenite G2 might melt to ~100% and at this stage, melt of pyroxenite reacts with peridotite to form a hybrid enriched peridotite lithology. Indeed, Rosenthal et al (2018) note that in upwelling heterogenous mantle domains, siliceous eclogitic melts will react with encapsulating mantle peridotite, effectively refertilising it and producing hybrid pyroxene-and garnet-rich rocks.…”

“…In addition, Figure 4 shows that the D Coe Al and D Coe Ti from Wang and Takahashi (1999) and Rosenthal et al (2018) are exceedingly smaller than those constrained by us at similar P-T conditions. The abundances of these elements in both studies were quantified by the EMP technique so that their accuracies were limited.…”

“…The results of this study strongly support the hypothesis that hybrid mantle heterogeneities such as Px1 may contribute to refertilization of the Earth's mantle. Starting from a deep peridotite-dominated mantle enclosing eclogites or pyroxenites, mantle refertilization results from a complex series of processes (e.g., Spandler et al, 2008;Rosenthal et al, 2018). Mantle heterogeneities undergo dynamic and polybaric transformation mostly driven by multiple episodes of partial melting and interactions with the surrounding mantle.…”

“…Their partial melts are expected to react with the surrounding peridotite either modifying the composition of the rising melts (Pilet et al, 2008;Mallik and Dasgupta, 2012 or creating new hybrid rocks, called secondary or stage 2 pyroxenites (e.g., Yaxley and Green, 1998;Sobolev et al, 2005Sobolev et al, , 2007Herzberg, 2006Herzberg, , 2011Lambart et al, 2012). Heterogeneous upwelling mantle is subject to continuous events of partial melting and melt-rock reactions that potentially replace the mafic components with a compositionally wide range of hybrid lithologies, including metasomatized peridotites and variably residual pyroxenites (e.g., Yaxley and Green, 1998;Spandler et al, 2008;Rosenthal et al, 2014Rosenthal et al, , 2018. Petrological studies on ultramafic massifs have interpreted some pyroxenites embedded in mantle peridotite as natural examples of secondary pyroxenites, originated through high-pressure melt-peridotite reactions (i.e., Garrido and Bodinier, 1999;Bodinier et al, 2008;Gysi et al, 2011;Marchesi et al, 2013;Borghini et al, 2013Borghini et al, , 2016Borghini et al, , 2019Montanini and Tribuzio, 2015).…”
