Melt-free and basaltic (complex alumino-silicate) melt-bearing specimens of fine-grained polycrystalline olivine (Mg0.9Fe0.1)2SiO4, tested at igh temperature and low frequency in torsional forced oscillation and microcreep, display markedly different behavior. For the melt-bearing aterials, superimposed upon the high-temperature background is a dissipation peak whose height varies systematically with melt fraction that is ttributed to elastically accommodated grain-boundary sliding facilitated… CONTINUE READING
