Summary The melting point Tm of iron at conditions of the Earth's inner core boundary (ICB) has been calculated from the dislocation theory of melting in metals. These calculations take into account the effects of pressure at ICB conditions and of po

Using measurements in the frequency domain the authors have measured quality factor Q and travel times of direct and side-reflected elastic waves in a 1.8 m long sample of Berea sandstone. The frequency domain travel rime (FDTT) method produces the c

The melting point Tm of iron at conditions of the Earth’s inner core boundary (ICB) has been calculated from the dislocation theory of melting in metals. Monte Carlo calculations were used to estimate uncertainties introduced by uncertainty in the

We have developed a general computation procedure DEFEQ that enables equilibrium defect concentrations in minerals to be quantitatively determined over the range of thermodynamic conditions that encompasses both laboratory experiments and Earth condi

By simultaneously solving the governing equations for defect formation and the relative conservation laws, the authors have made a general calculation of equilibrium concentrations of point defects in MgO as functions of temperature, oxygen fugacity

We have measured optical transmittance spectra in rhyolitic obsidian samples in the wavelength range λ = 380–5500 nm and at temperatures T from 19°–1145°C, above and below the softening point. From the transmittance, we calculated the absorpti

The shift of crystal field bands due to Fe2+ and Fe3+ has been measured as a function of pressure up to 50 kbar at room temperature. We have examined spin-allowed transitions in the infrared and spin-forbidden transitions in the visible and ultraviol

The observed systematic relations between velocities, density, and crystal structure in minerals are viewed as part of the general problem of the interactions of ions and electrons in solids. A complete explanation of these systematics would result f
