X‐SPEC: a 70 eV to 15 keV undulator beamline for X‐ray and electron spectroscopies
(
- Journal of Synchrotron Radiation
, 2021-02-10)
X‐SPEC is a high‐flux spectroscopy beamline at the KIT (Karlsruhe Institute of Technology) Synchrotron for electron and X‐ray spectroscopy featuring a wide photon energy range. The beamline is equipped with a permanent ...
Pedogenic carbonates as a proxy for palaeo-CO2 in the Palaeozoic atmosphere
(
- Elsevier
, 2006)
According to a model by Cerling (1991, 1999), the carbon isotope composition
of calcretes should depend on the soil type and the CO2-concentration in the atmosphere.
We have tested Cerling’s model by investigating 14 ...
Drag and drop of pores during grain boundary migration
(Univ. Bochum, 2006)
Untersucht werden die Wechselwirkungen zwischen Poren und Korngrenzen in Polykristallen, insbesondere das Ziehen einer Pore mit und die Separation einer Pore von einer wandernden Korngrenze. Zwei relevante Transportmechanismen ...
Crystallization of metastable monoclinic carnallite, KCl·MgCl2·6H2O: missing structural link in the carnallite family
(
- Acta Crystallographica Section C
, 2020)
During evaporation of natural and synthetic K–Mg–Cl brines, the formation of almost square plate-like crystals of potassium carnallite (potassium chloride magnesium dichloride hexahydrate) was observed. A single-crystal ...
Cryptic metasomatic agent measured in situ in Variscan mantle rocks: Melt inclusions in garnet of eclogite, Granulitgebirge, Germany
(
- Journal of Metamorphic Geology
, 2020)
Garnet of eclogite (formerly termed garnet clinopyroxenite) hosted in lenses of orogenic garnet peridotite from the Granulitgebirge, NW Bohemian Massif, contains unique inclusions of granitic melt, now either glassy or ...
The Preparation and Preliminary Characterisation of Three Synthetic Andesite Reference Glass Materials (ARM-1, ARM-2, ARM-3) for In Situ Microanalysis
(
- Geostandards and Geoanalytical Research
, 2019)
Three synthetic reference glasses were prepared by directly fusing and stirring 3.8 kg of high-purity oxide powders to provide reference materials for microanalytical work. These glasses have andesitic major compositions ...
New U–Pb zircon ages of Nyong Complex meta‐plutonites: Implications for the Eburnean/Trans‐Amazonian Orogeny in southwestern Cameroon (Central Africa)
(
- Geological Journal
, 2020-10-22)
New LA–ICP–MS U–Pb zircon ages from the Nyong Complex of southwestern Cameroon—a part of the West Central African Fold Belt—trace Late Mesoarchean (∼2,850 Ma), Middle Palaeoproterozoic (∼2,080 Ma), and Neoproterozoic ...
Progressive Changes in Magma Transport at the Active Serreta Ridge, Azores
(
- Geochemistry, Geophysics, Geosystems
, 2019)
Volcanism in the Eastern Azores Plateau occurs at large central volcanoes and along subaerial and submarine fissure zones, resulting from a mantle melting anomaly combined with transtensional stresses. Volcanic structures ...
Urban water systems under climate stress: An isotopic perspective from Berlin, Germany
(
- Hydrological Processes
, 2020-07-01)
Large urban areas are typically characterized by a mosaic of different land uses, with contrasting mixes of impermeable and permeable surfaces that alter “green” and “blue” water flux partitioning. Understanding water ...
Synthesis, crystal structure and structure–property relations of strontium orthocarbonate, Sr2CO4
(
- Acta Crystallographica Section B
, 2021-02-09)
Carbonates containing CO4 groups as building blocks have recently been discovered. A new orthocarbonate, Sr2CO4 is synthesized at 92 GPa and at a temperature of 2500 K. Its crystal structure was determined by in situ ...
