Metamorphism of CO and CO-like chondrites and comparisons with type 3 ordinary chondrites [PDF]
, 1991 P(論文)In order to explore their metamorphic history, thermoluminescence data have been obtained for 10 CO or CO-related chondrites from the Antarctic. Six have TL properties indicating low to intermediate levels of metamorphism, while Lewis Cliff 85332 ...

Iron Isotope Constraints on the Structure of the Early Solar System
The 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 ...

Titanium stable isotopic variations in chondrites, achondrites and lunar rocks [PDF]
, 2017 Titanium isotopes are potential tracers of processes of evaporation/condensation in the solar nebula and magmatic differentiation in planetary bodies. To gain new insights into the processes that control Ti isotopic variations in planetary materials, 25 ...

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

Metal size distributions in EH and EL chondrites [PDF]
, 2003 EL chondrites exhibit larger average metal grain sizes than EH chondrites, a difference attributed by Easton to metamorphic coarsening, as most EL chondrites are equilibrated, and most EH chondrites are unequilibrated.

Igneous Rim Accretion on Chondrules in Low-velocity Shock Waves
The 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.

Mössbauer Study of Weathering Products in Meteorites from the Atacama Desert
MagnetochemistryDuring their stay at the surface of the Earth, meteorites undergo terrestrial weathering. In particular, the iron-nickel alloys and iron sulfides that are abundant in many types of meteorites transform into oxides and oxihydroxides (magnetite, maghemite,
