X-ray Absorption Fine Structure (XAFS) spectroscopy has been widely used to characterize
the short-range order of glassy materials since the theoretical basis was established 45 …

The phenomenon of Extended X-Ray Absorption Fine Structure (EXAFS) has been known
for some time and was first treated theoretically by Kronig in the 1930s. Recent …

Carbonatite and silicate rocks occurring within a single magmatic complex may originate
through liquid immiscibility. We thus experimentally determined carbonatite/silicate melt …

Defining the molecular-scale structure and dynamics of silicate melts has been a long-term
goal of inorganic geochemists, igneous petrologists, ceramists, glass technologists, and …

The ultrasonic velocity and absorption of 32 silicate melts have been determined as a
function of temperature (1175–1925 K) and frequency (3–12 MHz). The samples include the …

Background A silicate melt phase is an essential component in nearly all igneous
processes. In a melt, the viscosity can decrease some 20 orders of magnitude below that of …

Glasses are widely used as analogues for the study of silicate melts. Although they are solid
materials, their structure is inherently complex and difficult to study. However, progress has …

Raman spectra of GeO 2 glass are recorded in situ as a function of pressure to 56 GPa at
room temperature. Under initial compression to 6 GPa the main 419-cm− 1 Raman band …

Coordination and local geometry around Si cations in silicate liquids are of primary
importance in controlling the chemical and physical properties of magmas. Pressure …

The viscosity-temperature relationships of nine melts in the Na 2 O FeO Fe 2 O 3 SiO 2
system (in equilibrium with air) have been measured in the temperature range of 1450–800° …
