Among primitive meteorites, CR chondrites have peculiar isotopic compositions, the origin of which is uncertain and may have involved contributions from primordial molecular cloud …

Oxygen-isotope ratios of olivine in type I (MgO-rich) and type II (FeO-rich) chondrules and olivine fragments in the matrix from the Tagish Lake meteorite (ungrouped C2) were …

We report on the mineralogy, petrography, and in situ measured oxygen-and magnesium- isotope compositions of eight porphyritic chondrules (seven FeO-poor and one FeO-rich) …
Determining the origins of chondrule precursors is key to constraining how material migrated in the early Solar System. Chondrules that were only partially melted during their formation …
Carbonaceous chondrites are some of the most primitive meteorites and derive from planetesimals that formed a few million years after the beginning of the solar system. Here …

Oxygen-isotope studies of carbonaceous chondrite chondrules are of pivotal importance for understanding of the evolution of the solar protoplanetary disk. It has been previously …

We present an overview of the chondrite groups focusing on the major constraints that can be derived on thermal history of silicates in the solar nebula from the mineralogical …

We review the 26Al ages of chondrules in various type 3.0 chondrites. The 26Al ages of chondrules are 1–3 Myr after calcium‐aluminum‐rich inclusion (CAI) for LL3. 0, CO3. 0, and …
Major advances in deciphering the record of nebula processes in chondrites can be attributed to analytical improvements that allow coordinated isotopic and mineralogical …
