“…4), and SIO is identified as poorly crystalline quartz. Highly weathered amygdaloidal, basaltic samples are Mineralogical determination using miniaturized laser ablation mass spectrometer 137 consistent with the presence of millerite, which is a lowtemperature calcite-and serpentine-associated mineral (Moody 1976;Anthony 1990;Schwarzenbach & Früh-Green 2009), and quartz is a documented pseudomorph of the olivine phenocrysts (Rex & Scott 1987). The ALP phase was identified to represent the mineralogy of the basaltic host rock to a large extent but in general, chlorite was surrounding the millerite crystals.…”

“…By contrast, Rudnick and Walker (2009) noticed that abyssal peridotites sampled near the seafloor are Re-enriched with respect to those coming from greater depths, implying a possible Re addition from seawater. Nevertheless, secondary sulfides are generally considered indicators of the remarkable variations of oxygen and sulfur fugacities in peridotites affected by serpentinization (Frost, 1985;Alt and Shanks, 2003;Frost and Beard, 2007;Delacour et al, 2008;Klein and Bach, 2009;Schwarzenbach et al, 2012), since primary sulfides become obliterated due to progressive desulfurization (sulfide leaching).…”
