Input files and movie visualizations for convection models discussed in Becker and Fuchs, "Generation of evolving plate boundaries and toroidal flow from visco-plastic damage-rheology mantle convection and continents", manuscript revised for G-Cubed
<p>These input files are for the CitcomS software as available on github.com/geodynamics/citcoms and used in the version under commit 2bda530. They can be used to recreate the models discussed in Becker and Fuchs (revised manuscript submitted to G-Cubed, 11/2023), with model codes discussed and listed in Table 1 of the preprint as provided here. We also provide selected animations of the time dependence of model output, referenced to the same model names.</p>

Data from: Acoustic and electrical properties of Fe-Ti oxides with application to the deep lunar mantle
<p>The overturn of titanium-rich mantle cumulates has been invoked to explain the structure and dynamics of the Moon. These dense cumulates are stable at the core-mantle boundary (CMB) and could explain field anomalies inferred from geophysical studies. We report the first acoustic and electrical experiments on natural ilmenite-rutile aggregates up to 4.5 GPa and 1920 K. Seismic velocities show a weak pressure and temperature dependence, with Vs ~4.2 (+/-0.2) km/s and Vp ~ 8.0 (+/-0.2) km/s at the CMB conditions. Conductivity increases by a factor > 10<sup>4</sup> over 373-1920 K and is >10<sup>3</sup> S/m above 1573 K. Seismic and electrical mixing models of Fe-Ti oxides - olivine rocks based on our results indicate that field velocity and conductivity estimates are reproduced satisfactorily with 3-16% Fe-Ti oxides and 20% melt. Interactions between this Ti-rich and melt-bearing layer and the adjacent core likely affect the cooling and magnetic history of the Moon.</p>

Model for the paper: Cause of enigmatic upper-mantle earthquakes in central Wyoming
<p>We use a large number of high-quality arrival-time data of local and teleseismic events to determine detailed 3-D Vp isotropic and anisotropic tomography of the crust and mantle down to 750 km depth beneath Wyoming and its adjacent areas. For details, see https://doi.org/10.1785/0220230333</p> <p>This dataset contains the obtained 3-D tomographic models of isotropic P-wave velocity, azimuthal anisotropy and radial anisotropy. </p>

Supplementary Data, Figures and Code - Europium in plagioclase-hosted melt inclusions reveals mantle melting modulates oxygen fugacity
<p>Electronic supplementary data, figures and code to the article Europium in plagioclase reveals mantle melting modulates oxygen fugacity. Data tables include major and trace element analyses, replicate analyses of secondary standards, which establish trace element data quality, a summary of new plagioclase-melt major and trace element data and data compiled from the literature, and recovered temperatures and oxygen fugacities, and spatial variations of plagioclase compositions around melt inclusions in phenocrysts extracted from sample D23-2 from the Juan de Fuca ridge, which were thermally homogenized over different periods of time (30 minutes, four hours, one day, and four days). The compressed archive contains Matlab scripts which may be used to recover temperatures from trivalent REE distributions in coexisting plagioclase crystals and melt inclusions or glasses.</p>

<p>These are the four supplementary data files for a paper accepted in the Journal of Geophysical Research (JGR), "Initial results from the Oman Drilling Project Multi-Borehole Observatory: Petrogenesis and ongoing alteration of mantle peridotite in the weathering horizon", 2021JB022729R, which are being uploaded here in conformance with JGR's requirement that data be placed in an open archive. The date of publication is not yet known, but JGR requires that the data be uploaded when the paper is accepted, so we have used the date of acceptance, November 20, 2021.</p>
