Journal ArticleDOI
Chemical‐ and Clapeyron‐induced buoyancy at the 660 km discontinuity
Donald J. Weidner,Yanbin Wang +1 more
TL;DR: In this article, the authors examined the impact of phase equilibria and equation of state measurements on defining the buoyancy associated with the 660 km discontinuity and concluded that there is no positive evidence for chemical-induced buoyancy across this discontinuity.
Journal ArticleDOI
Elasticity of single‐crystal orthoferrosilite
Jay D. Bass,Donald J. Weidner +1 more
TL;DR: The elastic moduli of a synthetic single crystal of pure FeSiO3, orthoferrosilite, have been measured at 1 bar and 20°C by Brillouin spectroscopy as discussed by the authors.
Journal ArticleDOI
Thermal equation of state of aluminum-enriched silicate perovskite
TL;DR: New pressure-volume-temperature data for silicate perovskite containing 5 mole percent Al2O3 has yielded different values of the equation of state parameters, with the bulk modulus being significantly smaller at lower mantle conditions than for aluminum-free perovkite, thus requiring adjustments in other components to match seismic observations.
Journal ArticleDOI
Effect of water on olivine‐wadsleyite phase boundary in the (Mg, Fe)2SiO4 system
TL;DR: In this paper, the phase boundary between San Carlos olivine and its high pressure phase, wadsleyite, have been studied comparatively in dry and water saturated condition, and both boundaries of the two-phase coexisting loop shift towards lower pressure or lower iron content, and the pressure width of the loop decreases to 0.3 GPa under saturated conditions at 1473 K.
Journal ArticleDOI
Elasticity of single crystal pyrope and implications for garnet solid solution series
TL;DR: In this article, the elastic moduli of a synthetic single crystal of pyrope (Mg 3 Al 2 Si 3 O 12 ) have been determined using a technique based on Brillouin scattering.
