Antigorite serpentinite affects mantle convection and temperature structure of upper mantle. Then the perpose of this study is understanding the plastic behavior of antigorite serpentinite in subduction zone by observing its microstructure. In this study, we used serpentinites from Erro-Tobbio peridotite body which underwent the deformation in subduction zone and has its history. And we observed the microstructure corresponding to the past deformation event.
