Sulfur‐bearing serpentine in carbonaceous chondrites
Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2864-2890, December 2025.Abstract A correlative multi‐technique approach, including electron microscopy and X‐ray synchrotron work, has been used to obtain both structural and compositional information of a sulfur‐bearing serpentine identified in several carbonaceous chondrites (Winchcombe CM2, Aguas Zarcas CM2, Ivuna CI, and Orgueil CI), and in Ryugu samples returned by the ...

Thermomagnetic Study of Chondrules [PDF]
Symposium - International Astronomical Union, 1980 Thermomagnetic and saturation magnetization curves were obtained for separate chondrules and fine matrix grains from one H- (Allegan) and four L-type (Bjurböle, Elenovka, Saratov, Nikolskoe) chondrites. Mineralogical and petrological data were recovered from chondrule thin sections.

Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2913-2934, December 2025.Abstract Enstatite chondrites formed under extremely reducing conditions in the protoplanetary disk. They are derived from two or more parent bodies, EH and EL, and both EH and EL groups contain petrologic type 3–6 samples. The rare lithophile‐ and halogen‐bearing sulfide, djerfisherite, occurs in low abundance in enstatite chondrites, most frequently ...

Raman Study of the Slobodka Ordinary Chondrite
Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1329-1344, November 2025.The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.

Petrography of phosphates in CI and CY carbonaceous chondrites
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2594-2622, November 2025.Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...

, 2009 It has been suggested that shock waves in the solar nebula formed the high temperature materials observed in meteorites and comets. It is shown that the temperatures at the inner rim of the solar nebula could have been high enough over a sufficient ...
