Dhofar 225 and Dhofar 735: Relationship to CM2 chondrites and metamorphosed carbonaceous chondrites, Belgica-7904 and Yamato-86720 [PDF]
, 2010 Dhofar (Dho) 225 and Dho 735 are carbonaceous chondrites found in a hot desert and having affinities to Belgica-like Antarctic chondrites (Belgica [B-] 7904 and Yamato [Y-] 86720).

Noble gases in enstatite chondrites II: The trapped component [PDF]
, 2002 The trapped noble gas record of 57 enstatite chondrites (E chondrites) has been investigated. Basically, two different gas patterns have been identified dependent on the petrologic type.

Reduced and unstratified crust in CV chondrite parent body
Nature 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 ...

Eos, 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 ...

The relationship between CK and CV chondrites [PDF]
, 2010 International audienceCK chondrites are highly oxidized meteorites containing abundant magnetite and trace amounts of Fe,Ni metal. Although the group is predominately composed of equilibrated meteorites (types 4-6), in recent years a significant number ...

“CY1” Chondrites Produced by Impact Dehydration of the CI Chondrite Parent Body
The Astrophysical Journal LettersThe recently proposed Yamato-type (CY) chondrites share significant similarities with CI chondrites and Ryugu. We present major and trace elemental, Re–Os, and mass-independent Ti, Cr, and Fe isotope data for seven CY chondrites. The elemental data along

Geological Journal, EarlyView.Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

Thermoluminescence studies of ordinary chondrites in the Japanese Antarctic meteorite collection, IV: Asuka ordinary chondrites [PDF]
, 2005 P(論文)We measured TL properties of ninety Asuka (A) ordinary chondrites (LL: 16, L: 27, H: 47) from Japanese Antarctic meteorite collection. Most of the chondrites had TL sensitivities over 0.1, corresponding to petrologic subtype 3.5-3.9.

Spectral Reflectance Properties (0.3–2.5 μm) of LL Ordinary Chondrites
The Astrophysical Journal Supplement SeriesSpectral characterization of asteroids relies on meteorite spectral calibration to constrain their surface mineralogy. We have conducted a comprehensive spectroscopic study of LL chondrites to shed light on the factors that control their reflectance ...

Clays and the Origin of Life: The Experiments
Life, 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 ...
