Two-phase late Paleozoic magmatism (~ 313–312 and ~ 299–298 Ma) in the Lusatian Block and its relation to large scale NW striking fault zones: evidence from zircon U–Pb CA–ID–TIMS geochronology, bulk rock- and zircon chemistry
(

, 2021-08-12)
Late Paleozoic (Variscan) magmatism is widespread in Central Europe. The Lusatian Block is located in the NE Bohemian Massif and it is part of the Saxothuringian Zone of the Variscan orogen. It is bordered by two major ...
Towards joint in situ determination of pressure and temperature in the large volume press exclusively from X‐ray diffraction
(
- Journal of Synchrotron Radiation
, 2023-06-21)
Since high‐pressure devices have been used at synchrotron facilities, accurate determination of pressure and temperature in the sample has been a crucial objective, particularly for experiments that simulate the Earth's ...
Data reduction for X‐ray serial crystallography using machine learning
(
- Journal of Applied Crystallography
, 2023-01-24)
Serial crystallography experiments produce massive amounts of experimental data. Yet in spite of these large‐scale data sets, only a small percentage of the data are useful for downstream analysis. Thus, it is essential ...
Clay mineral formation in Permian rocks of a geothermal borehole at Northern Upper Rhine Graben, Germany
(
- International Journal of Earth Sciences
, 2021-03-27)
Hydrothermally altered rhyolite rocks in the Permian Donnersberg Formation of a geothermal borehole in the Northern Upper Rhine Graben (Germany) were investigated to find out answers for the low hydraulic conductivity of ...
Authigenic and Detrital Carbonate Nd Isotope Records Reflect Pulses of Detrital Material Input to the Labrador Sea During the Heinrich Stadials
(
- Paleoceanography and Paleoclimatology
, 2023-01-28)
Limited constraints on the variability of the deep‐water production in the Labrador Sea complicate reconstructions of the strength of the Atlantic Meridional Overturning Circulation (AMOC) during the Late Quaternary. Large ...
Petrogenesis of a late-stage calc-alkaline granite in a giant S-type batholith: geochronology and Sr–Nd–Pb isotopes from the Nomatsaus granite (Donkerhoek batholith), Namibia
(
- International Journal of Earth Sciences
, 2021-04-07)
The late-tectonic 511.4 ± 0.6 Ma-old Nomatsaus intrusion (Donkerhoek batholith, Damara orogen, Namibia) consists of moderately peraluminous, magnesian, calc-alkalic to calcic granites similar to I-type granites worldwide. ...

Use of electron backscatter diffraction patterns to determine the crystal lattice. Part 2. Offset corrections
(
- Journal of Applied Crystallography
, 2023-02-24)
A band width determination using the first derivative of the band profile systematically underestimates the true Bragg angle. Corrections are proposed to compensate for the resulting offset Δa/a of the mean lattice parameters ...
Accessories in Kaiserstuhl carbonatites and related rocks as accurate and faithful recorders of whole rock age and isotopic composition
(
- International Journal of Earth Sciences
, 2021-12-09)
The accessories perovskite, pyrochlore, zirconolite, calzirtite and melanite from carbonatites and carbonate-rich foidites from the Kaiserstuhl are variously suited for the in situ determination of their U–Pb ages and Sr, ...
Water contents of nominally anhydrous orthopyroxenes from oceanic peridotites determined by SIMS and FTIR
(
- Mineralogy and Petrology
, 2021-08-27)
This study presents new secondary ion mass spectrometry (SIMS) reference materials (RMs) for measuring water contents in nominally anhydrous orthopyroxenes from upper mantle peridotites. The enstatitic reference orthopyroxenes ...
