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.

What Martian Meteorites Reveal About the Interior and Surface of Mars
Journal of Geophysical Research: Planets, 2020 Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total of 262 individual samples originating from at least 11 ejection events.

The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites [PDF]
Astrophysical Journal Supplement Series, 2017 We present a comprehensive evolutionary model of the Sun’s protoplanetary disk, constructed to resolve the “CAI storage problem” of meteoritics. We predict the abundances of calcium-rich, aluminum-rich inclusions (CAIs) and refractory lithophile elements

Classification of meteorites by petrophysical methods [PDF]
Bulletin of the Geological Society of Finland, 1983 The low field magnetic susceptibility, natural remanent magnetization (NRM) and bulk density were measured for 75 meteorite samples from 54 meteorites ranging from achondrites through chondrites and stony-irons to irons.

Linking asteroids and meteorites to the primordial planetesimal population
Geochimica et Cosmochimica Acta, 2020 Meteorites provide a unique insight into early Solar System processes. However, to fully interpret this record requires that these meteorites are related back to their source asteroids and ultimately to the original planetesimal population that formed ...

The breakup of the L-chondrite parent body 466 Ma and its terrestrial effects – a search for a mid-Ordovician biodiversity event [PDF]
Estonian Journal of Earth Sciences, 2023 About a third of all meteorites that fall on Earth today, the stony L-chondrites, originate from a major breakup event in the asteroid belt 466 Ma, in the early Darriwilian.

Method Development for the Analysis of Carbonaceous Chondrites by Laser Desorption/Ionization and Secondary Ion Time-of-Flight Mass Spectrometry. [PDF]
J Mass SpectromABSTRACT This study focuses on the development of a laser desorption/ionization mass spectrometric method for analyzing carbonaceous chondrites, meteorites that may hold clues to the origin of life. Since carbonaceous chondrites are only available in small quantities, we initially designed an artificial meteorite material (the mineral forsterite) doped

Microbial Populations of Stony Meteorites: Substrate Controls on First Colonizers
Frontiers in Microbiology, 2017 Finding fresh, sterilized rocks provides ecologists with a clean slate to test ideas about first colonization and the evolution of soils de novo. Lava has been used previously in first colonizer studies due to the sterilizing heat required for its ...
