The flow of material and the seismic signature of subduction zones are highly dependent on the elastic propertiesof two major types of hydrated minerals: serpentines (antigorite, lizardite and chrysotile) produced by thehydration of mantle minerals and glaucophane, a marker of blueschists and eclogites, which are metamorphicfacies characteristic of subduction zones. Detection of these phases is sometime difficult. It is important to knowtheir elastic properties in order to better understand the seismic images. The goal of this work is to measure andcalculate the elastic properties of hydrated minerals by Brillouin spectroscopy (for antigorite and glaucophane)and ab initio calculations (for lizardite). The precise knowledge of such propertie...
