Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

On the origin of enstatite chondrite chondrules based on their petrography and comparison with experimentally produced chondrules [PDF]
, 1994 The recent discovery of several types 3 and 4 enstatite chondrites (EC) in the Antarctic collection increases greatly the ability to compare unaltered, naturally-formed EC chondrules with chondrules produced experimentally from melts of enstatitic ...

Uranium isotopic composition and absolute ages of Allende chondrules [PDF]
, 2015 A handful of events, such as the condensation of refractory inclusions and the formation of chondrules, represent important stages in the formation and evolution of the early solar system and thus are critical to understanding its development.

Nitrogen isotopes in chondrules: signatures of precursors and formation processes [PDF]
, 2008 Nitrogen isotope abundance of 68 individual chondrules separated from six ordinary, two carbonaceous and two enstatite chondrites has been analysed. N composition of chondrules from ordinary and carbonaceous chondrites generally shows large variation and

Classification of stony meteorites and chondrules – the case of meteorite Jesenice
Geologija, 2012 In the first part of the paper there is a description about genesis of meteorites, in particularly about stony meteorites– chondrites, since meteorite Jesenice is an ordinary L chondrite. Chondrules represent main part of the mass ofchondritic meteorites.

Microspherules formed by lightning strikes
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 743-767, May 2026.Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Volatile-rich chondrules in the Allende meteorite [PDF]
, 1986 P(論文)A new type of chondrules in the Allende meteorite is rich in volatile elements and shows porphyritic textures similar to terrestrial basalts. This unique type is termed Type V to supplement H. Y. McSWEEN'S (Geochim. Cosmochim.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Planetesimal Impact Vapor Plumes and Nebular Shocks Form Chondritic Mixtures
The Planetary Science JournalThe origin of chondrules and the chondritic sedimentary rocks that dominate the meteoritic record is a long-standing problem in planetary science. Here, we develop a physical model for the formation of chondritic mixtures as an outcome of vaporizing ...

Did a Complex Carbon Cycle Operate in the Inner Solar System?
Life, 2020 Solids in the interstellar medium consist of an intimate mixture of silicate and carbonaceous grains. Because 99% of silicates in meteorites were reprocessed at high temperatures in the inner regions of the Solar Nebula, we propose that similar levels of
