Classification of several Yamato-75 chondrites (IV) [PDF]

P(論文)An electron microprobe analyzer was used to determine the chemical compositions of olivines and orthopyroxenes in six chondrites, i.e. Yamato-75119,91,-75124,91,-75125,91,-75126,91,-75128,92 and -75133,93.

Cosmic-ray exposure ages of enstatite chondrites [PDF]

, 2000
P(論文)Eleven enstatite (E-) chondrites were analyzed for abundances and isotopic ratios of noble gases by total melting. Light noble gases, He, Ne and Ar are discussed.

Hydrous Chondrites under Shock

The Astrophysical Journal
We examine the shock response of a chondrule-like multicomponent silicate melt enriched with 2 wt% H _2 O, representative of hydrous chondrites, using ab initio molecular dynamics.

Thermomagnetic analysis of meteorites. 3: C3 and C4 chondrites [PDF]

, 1974
Thermomagnetic analysis on all of the C3 and C4 chondrites, conducted under conditions of controlled oxygen fugacity, indicates the presence of a thermally unstable component in at least 5 of the C3 chondrites which upon heating results in magnetite ...

Impact-driven oxidation of organics explains chondrite shock metamorphism dichotomy

Nature Communications
Shocked 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.

Fe-Ni metal in primitive chondrites: Indicators of classification and metamorphic conditions for ordinary and CO chondrites

, 2008
We report the results of our petrological and mineralogical study of Fe-Ni metal in type 3 ordinary and CO chondrites, and the ungrouped carbonaceous chondrite Acfer 094.

Study of the Extraterrestrial Materials at Antarctica, III : On the Yamato Meteorites

Antarctic Record, 1973
Antarctica is thought to be the most suitable place for searching extraterrestrial materials. Since 1965, we have been studying microtektite and cosmic dust in Antarctica.

Magnetic classification of stony meteorites: 2. Non-ordinary chondrites

, 2008
A database of magnetic susceptibility (χ) measurements on different non-ordinary chondrites (C, E, R, and ungrouped) populations is presented and compared to our previous similar work on ordinary chondrites. It provides an exhaustive study of the amount

The Dehydration of Serpentines and Extraction of Water

The Planetary Science Journal
Some groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,
