Abstract
More significant rodingitization affected mafic doleritic dykes that intrude wehrlites: this alteration occurred in parallel to serpentinization of hosting ultramafics via subsequent circulation of relatively alkaline and hydrous fluids. We have calculated that this occurred under low to moderate P-T conditions (180-320â¯Â°C, Pâ¯ââ¯2-5â¯kbar). Circulation of Ca-rich fluids at shallower crustal levels was responsible for local carbonation phenomena, mostly affecting ultramafic and mafic pillow lavas.
