Sampling soil water along the pF curve for δ2H and δ18O analysis
(
- Hydrological Processes
, 2020)
Soil water stable isotopes are widely used across disciplines (e.g., hydrology, ecology, soil science, and biogeochemistry). However, the full potential of stables isotopes as a tool for characterizing the origin, flow ...
The Effect of Water on Ionic Conductivity in Olivine
(
- Journal of Geophysical Research: Solid Earth
, 2020)
High-temperature ionic conductivity in olivine single crystals has been measured in the [100], [010], and [001] crystallographic orientations as a function of pressure from 2 to 10 GPa, temperature from 1450 to 2180 K, and ...
NanoSr – A New Carbonate Microanalytical Reference Material for In Situ Strontium Isotope Analysis
(
- Geostandards and Geoanalytical Research
, 2019)
The in situ measurement of Sr isotopes in carbonates by MC-ICP-MS is limited by the availability of suitable microanalytical reference materials (RMs), which match the samples of interest. Whereas several well-characterised ...
Pre-Klondikean oxidation prepared the ground for Broken Hill-type mineralization in South Africa
(
- Terra Nova
, 2020)
New Cu isotope data obtained on chalcopyrite from the Black Mountain and the Broken Hill deposits in the medium- to high-grade metamorphic Aggeneys-Gamsberg ore district (South Africa) require a revision of our understanding ...
The history of the Tissint meteorite, from its crystallization on Mars to its exposure in space: New geochemical, isotopic, and cosmogenic nuclide data
(
- Meteoritics & Planetary Science
, 2020)
The Tissint meteorite fell on July 18, 2011 in Morocco and was quickly recovered, allowing the investigation of a new unaltered sample from Mars. We report new high-field strength and highly siderophile element (HSE) data, ...
Decoding the complex internal chemical structure of garnet porphyroblasts from the Zermatt area, Western Alps
(
- Journal of Metamorphic Geology
, 2019)
Garnet is a prototypical mineral in metamorphic rocks because it commonly preserves chemical and textural features that can be used for untangling its metamorphic development. Large garnet porphyroblasts may show extremely ...
A novel experimental approach for nanostructure analysis: simultaneous small-angle X-ray and neutron scattering
(
- Journal of Applied Crystallography
, 2020)
Exploiting small-angle X-ray and neutron scattering (SAXS/SANS) on the same sample volume at the same time provides complementary nanoscale structural information in two different contrast situations. Unlike an independent ...
The site-symmetry induced representations of layer groups on the Bilbao Crystallographic Server
(
- Journal of Applied Crystallography
, 2019)
The section of the Bilbao Crystallographic Server (http://www.cryst.ehu.es) dedicated to subperiodic groups includes a new tool called LSITESYM for the study of materials with layer and multilayer symmetry. This new program, ...
Combined X-ray and neutron single-crystal diffraction in diamond anvil cells
(
- Journal of Applied Crystallography
, 2019)
It is shown that it is possible to perform combined X-ray and neutron single-crystal studies in the same diamond anvil cell (DAC). A modified Merrill–Bassett DAC equipped with an inflatable membrane filled with He gas has ...
Effect of Fe3+ on Phase Relations in the Lower Mantle: Implications for Redox Melting in Stagnant Slabs
(
- Journal of Geophysical Research: Solid Earth
, 2019)
Recent studies have revealed that Earth's deep mantle may have a wider range of oxygen fugacities than previously thought. Such a large heterogeneity might be caused by material subducted into the deep mantle. However, ...
