... The normalization values are from Sun and McDonough (1989). Data source for the Troodos ophiolite: the melt inclusions of the LPL (Portnyagin et al., 1997); the melt inclusions of the boninites in the UPL (Hu et al., 2021); the melt inclusions of the infill lavas in the UPL (Portnyagin et al., 1996); volcanic glasses of LPL and UPL are from Pearce and Robinson (2010), Osozawa et al. (2012), Regelous et al. (2014), Golowin et al. (2017), Woelki et al. (2018Woelki et al. ( , 2019Woelki et al. ( , 2020. Further classification of LPL and UPL of the Troodos ophiolite are after Pearce and Robinson (2010) and Osozawa et al. (2012), respectively. ...

... NTDs are commonly related to the magmatic segmentation and variations in the magmatic budget along the ridge axis with lower melt production at the NTDs regions compared to segment centers (e.g., Carbotte et al., 2016;Lin et al., 1990;Macdonald et al., 1988;Sempéré et al., 1993). Previous studies have shown that discontinuities like fracture zone/transform fault and NTDs are found bounding different chemical domains (Carbotte et al., 2016;Hamelin et al., 2010;Langmuir & Bender, 1984;Mallick et al., 2019;Meyzen et al., 2005;Smith et al., 1998). Mallick et al. (2019) showed from the geochemical variations of MORB along the East Pacific Rise that even the smallest discontinuities like devals (deviations from axial linearity, Langmuir et al., 1986) often correspond to changes in mantle source chemistry. ...
