Porosity and density of ordinary chondrites: Clues to the formation of friable and porous ordinary chondrites [PDF]
Meteoritics & Planetary Science, 2003 Abstract— Densities and porosities of meteorites are physical properties that can be used to infer characteristics of asteroid interiors. We report density and porosity measurements of 42 pieces of 30 ordinary chondrites and provide a quantification of the errors of the gas pycnometer method used in this study.

Data-driven classification of ordinary chondrites and asteroidal metal potential evaluation [PDF]
Scientific ReportsOrdinary chondrites (OCs) comprise ~ 87% of meteorites and are key to decoding early Solar System processes, yet H–L–LL classification is often ambiguous, especially between L and LL.

Impact-driven oxidation of organics explains chondrite shock metamorphism dichotomy [PDF]
Nature CommunicationsShocked meteorites can be used to probe the dynamics of the early Solar system. Carbonaceous chondrites are less shocked than ordinary chondrites, regardless of the degree of aqueous alteration.

Рentlandite from ordinary chondrites of the Urals
Литосфера, 2016 Some new data on the chemical composition and morphology of the pentlandite from meteorites Ural (H5-6), Kunashak (L5-6), Ozernoye (L5), Severny Kolchim (H3), Kargapole (H4), and Chelyabinsk (LL5) are resulted in the paper. We found a natural decrease in

Shock metamorphism of ordinary chondrites [PDF]
Geochimica et Cosmochimica Acta, 1991 AbstractA revised petrographic classification of progressive stages of shock metamorphism of ordinary chondrites is proposed. Six stages of shock (S1 to S6) are defined, based on shock effects in olivine and plagioclase as recognized by thin section microscopy.

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.

EVALUATION OF THERMAL METAMORPHISM TEMPERATURE OF EQUILIBRATED ORDINARY CHONDRITES
Геодинамика и тектонофизика, 2022 The article provides an evaluation of thermal metamorphism temperatures on chondrite parent bodies using an olivine-Сr spinel geothermometer. To calculate temperatures, the results of EPMA analysis of the major and trace elements in olivine and Cr spinel
