The high‐temperature measurements of elastic constants and related temperature
derivatives of nine minerals of interest to geophysical and geochemical theories of the …

Here we provide an appraisal of the Poisson's ratios (υ) for natural elements, common
oxides, silicate minerals, and rocks with the purpose of searching for naturally auxetic …

In this chapter I present a compilation of the elastic moduli of minerals and related
substances which may be of use in geophysical or geochemical calculations. The discipline …

The bulk chemical composition of the Upper Mantle (“pyrolite”) is derived from experimental
and petrological studies of the complementary relationships between basaltic magmas and …

We compare the predictions of compositional models of the mantle transition zone to
observed seismic properties by constructing phase diagrams in the MgO‐FeO‐CaO‐Al2O3 …

The first high‐temperature data on the nine adiabatic elastic moduli for iron‐bearing olivine
are reported. These measurements are on two single‐crystal specimens of natural olivine at …

The availability of precise determinations of unit cell volumes of mantle minerals as functions
of both pressure and temperature through synchotron-based X-ray diffraction has motivated …

As an abundant component of Earth's upper mantle, forsterite (Mg2SiO4) has been the
subject of extensive investigation for many decades. The pressure dependences of sound …

In the past 6 years, state-of-the-art techniques have been developed for the studies of elastic
properties of polycrystalline and single-crystal materials using simultaneous ultrasonic and …

Abstract BED I of Olduvai Gorge has yielded some of the most important hominid fossils in
the world, but precise age estimates have been elusive. Here we report new dating results …
