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.

Stable Nitrogen Isotope Analysis of Amino Acids by Orbitrap Mass Spectrometry: Application for Extraterrestrial Samples. [PDF]
Rapid Commun Mass SpectromABSTRACT Background Obtaining isotopic data on soluble organic compounds, such as amino acids, in extraterrestrial samples is crucial for understanding their origins, prebiotic chemistry, and potential contamination. Conventional GC‐IRMS requires grams of material to measure isotopic compositions, limiting the analysis of low‐concentration organics in ...
