Title: Electronic environments of ferrous iron in rhyolitic and basaltic glasses at high pressure: Silicate Glasses at High Pressure

Abstract

The physical properties of silicate melts within Earth's mantle affect the chemical and thermal evolution of its interior. Chemistry and coordination environments affect such properties. We have measured the hyperfine parameters of iron-bearing rhyolitic and basaltic glasses up to ~120 GPa and ~100 GPa, respectively, in a neon pressure medium using time domain synchrotron Mössbauer spectroscopy. The spectra for rhyolitic and basaltic glasses are well explained by three high-spin Fe²⁺-like sites with distinct quadrupole splittings. Absence of detectable ferric iron was confirmed with optical absorption spectroscopy. The sites with relatively high and intermediate quadrupole splittings are likely a result of fivefold and sixfold coordination environments of ferrous iron that transition to higher coordination with increasing pressure. The ferrous site with a relatively low quadrupole splitting and isomer shift at low pressures may be related to a fourfold or a second fivefold ferrous iron site, which transitions to higher coordination in basaltic glass, but likely remains in low coordination in rhyolitic glass. These results indicate that iron experiences changes in its coordination environment with increasing pressure without undergoing a high-spin to low-spin transition. We compare our results to the hyperfine parameters of silicate glasses of different compositions. With the assumption thatmore »« less

Pressure effect on the electronic structure of iron in Mg,Fe Si, Al O{sub 3} perovskite : a combined synchrotron Mossbauer and x-ray emission spectroscopy study up to 100 GPa.

Journal Article Li, J ; Sturhahn, W ; Jackson, J M ; ... - Phys. Chem. Miner.

We investigated the valence state and spin state of iron in an Al-bearing ferromagnesian silicate perovskite sample with the composition (Mg0.88Fe0.09)(Si0.94Al0.10)O3 between 1 bar and 100 GPa and at 300 K, using diamond cells and synchrotron M{umlt o}ssbauer spectroscopy techniques. At pressures below 12 GPa, our Mossbauer spectra can be sufficiently fitted by a ''two-doublet'' model, which assumes one ferrous Fe2+-like site and one ferric Fe3+-like site with distinct hyperfine parameters. The simplest interpretation that is consistent with both the M{umlt o}ssbauer data and previous X-ray emission data on the same sample is that the Fe2+-like site is high-spin Fe2+,more »« less

Journal Article Pardo, Olivia S. ; Dobrosavljevic, Vasilije V. ; Sturhahn, Wolfgang ; ... - Physics and Chemistry of Minerals

Complex mixtures of sulfates, silicates, and ice have been observed in a variety of planetary environments on Earth, Mars and the icy satellites of the solar system. Characterizing the properties of the corresponding compositional endmembers is important for understanding the interiors of a range of planetary bodies in which these phases are observed. To measure the electronic and vibrational properties of the pure ferrous iron endmember of the kieserite group, szomolnokite, (FeSO₄∙H₂O), we have performed synchrotron ⁵⁷Fe nuclear resonant inelastic and forward scattering experiments in the diamond-anvil cell up to 14.5 GPa.

Journal Article Clark, Alisha N. ; Lesher, Charles E. ; Jacobsen, Steven D. ; ... - Journal of Geophysical Research. Solid Earth

Independent measurements of the volumetric and elastic properties of Columbia River basalt glass were made up to 5.5 GPa by high-pressure X-ray microtomography and GHz-ultrasonic interferometry, respectively. The Columbia River basalt displays P and S wave velocity minima at 4.5 and 5 GPa, respectively, violating Birch’s law. These data constrain the pressure dependence of the density and elastic moduli at high pressure, which cannot be modeled through usual equations of state nor determined by stepwise integrating the bulk sound velocity as is common practice. We propose a systematic variation in compression behavior of silicate glasses that is dependent on themore »« less

Influence of Radiation and Multivalent Cation Additions on Phase Separation and Crystallization of Glass

Technical Report Weinberg, Michael C ; Uhlmann, Donald R ; Smith, Gary L

This report presents results of: (1) measurement of valence state ratios of iron in glass, and (2) a study of the effect of iron redox ratio on phase separation behavior in a glass. The redox ratio of iron in two sodium silicate (NS) glasses has been determined using a colorimetric method, Moessbauer analysis, and optical absorption. The experimental procedures were described in a previous report. We found that these three methods gave excellent agreement for the values of the Fe++/Fe+++ (redox ratio) in the glasses. Also, using the results of the colorimetric analysis we were able to find the extinctionmore »« less

Structural environment around Th sup 4+ in silicate glasses: Implications for the geochemistry of incompatible Me sup 4+ elements

Journal Article Farges, F - Geochimica et Cosmochimica Acta; (United States)

The structural environment around Th{sup 4+} in several silicate glasses containing 1-3 wt% Th{sup 4+} was investigated as a function of melt composition and polymerization using Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy. One set of glasses had the bulk chemical composition of monticellite (MO), diopside (DI), anorthite (AN), albite (AL), olivine basalt (O-BAS), tholeiitic basalt (T-BAS), calc-alkaline dacite (DAC), and calc-alkaline rhyolite (RHY). A second set of Th-bearing glasses had the bulk Al composition but also contained either 5.5 wt% F or 2,000 ppm Cl.
