..., serpentinites from NMM and SMM contain only antigorite, the H T polytype of serpentine, supporting a deeper mantle wedge origin. Although the Erro Tobbio peridotite is noted as of mantle wedge origin, it originates from oceanic mantle, equated with abyssal peridotite serpentinized by a seawater-derived fluid...
