The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical 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.

Grain Size Effects on Visible and Near-infrared (0.35–2.5 μm) Laboratory Spectra of Ordinary Chondrite and HED Meteorites

open access: yesThe Planetary Science Journal, 2023
Remote spectral characterization of near-Earth asteroids (NEAs) relies on laboratory spectral calibration to constrain their surface composition, including mineral chemistry and relative mineral abundances.

Iron Isotope Constraints on the Structure of the Early Solar System

open access: yesThe Astrophysical Journal Letters, 2023
The recent advent of nontraditional isotopic systems has revealed that meteorites display a fundamental isotopic dichotomy between noncarbonaceous (NC) and carbonaceous (C) groups, which represent material from the inner and outer solar system ...

The Okhansk Meteorite: Specifics of Composition, Structure, and Genesis [PDF]

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2016
The Okhansk meteorite fell on August 18, 1887 near the village of Tabor, about 15 km away from the town of Okhansk in Perm province and weighed 186.5 kg (the total weight of collected fragments, according to P.I. Krotov, was more than 245 kg).

Igneous Rim Accretion on Chondrules in Low-velocity Shock Waves

open access: yesThe Astrophysical Journal, 2023
Shock-wave heating is a leading candidate for the mechanisms of chondrule formation. This mechanism forms chondrules when the shock velocity is in a certain range.

Reduced and unstratified crust in CV chondrite parent body

open access: yesNature Communications, 2017
Meteorites may unlock the history of the early solar system. Here, the authors find, through Ca-Fe-rich secondary phases, that the distinction between reduced and oxidized CV chondrites is invalid; therefore, CV3 chondrites are asteroid fragments that ...

Chondrites

open access: yesEos, Transactions American Geophysical Union, 1971
Because of their numerical dominance among meteorite falls, their great age, and their primitive (i.e., quasisolar) compositions, the chondrites are central to discussions of the origin and early history of the solar system. The bibliography includes most American contributions m this field from 1967 to 1970, and this report attempts to summarize our ...

Clays and the Origin of Life: The Experiments

open access: yesLife, 2022
There are three groups of scientists dominating the search for the origin of life: the organic chemists (the Soup), the molecular biologists (RNA world), and the inorganic chemists (metabolism and transient-state metal ions), all of which have ...
