Nanosecond laser ablation - multi-collector ICP-mass spectrometry for in situ Fe isotopic analysis of micro-meteorites : application to µm-sized glassy cosmic spherules Universiteit Gent
A large meteoritic event over Antarctica ca. 430 ka ago inferred from chondritic cosmic spherules from the Sør Rondane Mountains Vrije Universiteit Brussel
Large airbursts, the most frequent hazardous impact events, are estimated to occur orders of magnitude more frequently than crater-forming impacts. However, finding traces of these events is impeded by the difficulty of identifying them in the recent geological record. Here, we describe condensation spherules found on top of Walnumfjellet in the Sør Rondane Mountains, Antarctica. Affinities with similar spherules found in EPICA Dome C and ...

The parent body controls on cosmic spherule texture: Evidence from the oxygen isotopic compositions of large micrometeorites Vrije Universiteit Brussel
High-precision oxygen isotopic compositions of eighteen large cosmic spherules (>500 µm diameter) from the Atacama Desert, Chile, were determined using IR-laser fluorination – Isotope Ratio Mass spectrometry. The four discrete isotopic groups defined in a previous study on cosmic spherules from the Transantarctic Mountains (Suavet et al., 2010) were identified, confirming their global distribution. Approximately 50% of the studied cosmic ...
