Chondrule size averaging in two and three dimensions
Meteoritics &Planetary Science, EarlyView.Abstract Chondrule sizes are an important discriminant of chondrite groups and chondrule formation theories. Yet most studies report 2‐D sizes without attempting the somewhat tedious corrections to 3‐D proposed in the past literature. I show here that 3‐D size averages can be simply calculated directly from 2‐D averages of appropriate powers of sizes ...

Thermal history of an amoeboid olivine aggregate in the early solar nebula
Meteoritics &Planetary Science, EarlyView.Abstract Carbonaceous chondrites commonly contain amoeboid olivine aggregates (AOAs). Here, we investigated an AOA in the CR chondrite Y‐793261. This AOA contains an unstable assemblage of forsterite and quartz. We found a rare occurrence of enstatite and quantitatively discuss its formation process.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Meteoritics &Planetary Science, EarlyView.Abstract Public fascination with impact craters often drives bold speculations, but rigorous verification is critical. In southeastern Bavaria, numerous depressions have been proposed to represent impact craters associated with a catastrophic event in Celtic times (between 900 BC and 600 BC)—the so called “Chiemgau Impact.” To date, the evidence ...

Meteoritics &Planetary Science, EarlyView.Abstract Apatite is often the most rare earth element (REE)‐enriched mineral in chondritic meteorites. REE enrichment and fractionation levels in apatite grains can give insight into the aqueous fluids in which they formed and the conditions prevailing within the host body. In this study, we applied synchrotron X‐ray fluorescence (SXRF) spectroscopy to
