Major, minor, trace element and isotopic composition of serpentine (antigorite and lizardite), mantle and metamorphic olivine from the Erro-Tobbio Massif peridotites (Italy)

This dataset presents in situ analyses of major, minor, trace elements and boron and oxygen isotopic composition of lizardite, antigorite and olivine from the Erro-Tobbio Massif serpentinites. This study reveals the chemical characteristics of the hydration and dehydration events recorded in the Erro-Tobbio serpentinites, from the oceanic stage to the subduction of an ancient oceanic lithosphere.
