A zircon classification scheme for sedimentary provenance analysis using radiation damage
(
- Geological Journal
, 2023-04-10)
<p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en">Detrital single‐grain zircon U–Pb geochronology is a powerful tool for provenance studies if information on the source rocks is available. This paper proposes ...
Hard X‐ray full‐field nanoimaging using a direct photon‐counting detector
(
- Journal of Synchrotron Radiation
, 2023-02-01)
Full‐field X‐ray nanoimaging is a widely used tool in a broad range of scientific areas. In particular, for low‐absorbing biological or medical samples, phase contrast methods have to be considered. Three well established ...
Capturing the structural and compositional variability of Opalinus Clay: constraints from multidisciplinary investigations of Mont Terri drill cores (Switzerland)
(
- Environmental Earth Sciences
, 2021-06-02)
Opalinus Clay is considered a potential host rock for radioactive waste disposal. The Jurassic claystone formation is composed of several facies and subfacies types, which are characterized by varying amounts of quartz, ...
Updates in SASfit for fitting analytical expressions and numerical models to small‐angle scattering patterns
(
- Journal of Applied Crystallography
, 2022-11-21)
Small‐angle scattering is an increasingly common method for characterizing particle ensembles in a wide variety of sample types and for diverse areas of application. SASfit has been one of the most comprehensive and flexible ...

The chondrite breccia of Antonin (L4‐5)—A new meteorite fall from Poland with a heterogeneous distribution of metal
(
- Meteoritics & Planetary Science
, 2022-08-23)
On July 15, 2021, a huge fireball was visible over Poland. After the possible strewn field was calculated, the first and so far only sample, with a mass of 350 g, was discovered 18 days after the fireball event. The Antonin ...
