Shear-wave attenuation and dispersion in melt-bearing olivine polycrystals: 1. Specimen fabrication and mechanical testing

Jackson, Ian; Faul, Ulrich; Fitz Gerald, John; Tan, B


Five melt-bearing polycrystalline olivine aggregates have been newly prepared by hot isostatic pressing and tested at high temperature and pressure with torsional forced-oscillation and microcreep methods. Cylindrical specimens, varying in average grain size from 7 to 52 μm, were annealed and then tested during slow staged cooling under 200 MPa pressure from maximum temperatures of 1240-1300°C where they contained basaltic melt fractions ranging from ∼0.0001 to 0.037. For temperatures ≥ 1000°C,...[Show more]
