Seismic properties of Anita Bay Dunite: an Exploratory Study of the Influence of Water

Aizawa, Yoshitaka; Barnhoorn, Auke; Faul, Ulrich; Fitz Gerald, John; Jackson, Ian; Kovacs, Istvan


As a pilot study of the role of water in the attenuation of seismic waves in the Earth's upper mantle, we have performed a series of seismic-frequency torsional forced-oscillation experiments on a natural (Anita Bay) dunite containing accessory hydrous phases, at high temperatures to 1300°C and confining pressure (Pc) of 200 MPa, within a gas-medium high-pressure apparatus. Both oven-dried and pre-fired specimens] wrapped in Ni-Fe foil within the (poorly) vented assembly were recovered...[Show more]
