Chondrule-like objects and Ca-Al-rich inclusions in Ryugu may potentially be the oldest Solar System materials [PDF]
Nature Communications, 2023 Chondrule-like objects and CAIs in the Ryugu samples are early generations of chondrules and possibly oldest solids in the Solar System. They were transported from the inner solar nebula to the formation location of the Ryugu original parent body.

Trace element geochemistry of ordinary chondrite chondrules: the type I/type II chondrule dichotomy [PDF]
, 2015 We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for carbonaceous chondrites, with rare earth element (REE) concentrations ...

Formation of chondrule analogs aboard the International Space Station [PDF]
Meteoritics and Planetary Science, 2021 Chondrules are thought to play a crucial role in planet formation, but the mechanisms leading to their formation are still a matter of unresolved discussion.

An evolutionary system of mineralogy. Part III: Primary chondrule mineralogy (4566 to 4561 Ma). [PDF]
Am Mineral, 2021 Information-rich attributes of minerals reveal their physical, chemical, and biological modes of origin in the context of planetary evolution, and thus they provide the basis for an evolutionary system of mineralogy. Part III of this system considers the

Accretion of a large LL parent planetesimal from a recently formed chondrule population. [PDF]
Sci Adv, 2020 LL chondrite cooling histories require a ≥150-km parent body and accretion concurrent with LL chondrule formation. Chondritic meteorites, derived from asteroidal parent bodies and composed of millimeter-sized chondrules, record the early stages of ...

Chondrule Properties and Formation Conditions
Space Science ReviewsChondrules are iconic sub-millimeter spheroids representing the most abundant high-temperature dust formed during the evolution of the circumsolar disk. Chondrules have been the subject of a great deal of research, but no consensus has yet emerged as to ...

Oxygen isotope systematics of chondrule olivine, pyroxene, and plagioclase in one of the most pristine CV3Red chondrites (Northwest Africa 8613). [PDF]
Meteorit Planet Sci, 2019 We performed in situ oxygen three‐isotope measurements of chondrule olivine, pyroxenes, and plagioclase from the newly described CVRed chondrite NWA 8613.

Chondrule formation by collisions of planetesimals containing volatiles triggered by Jupiter’s formation [PDF]
Scientific ReportsChondrules are spherical or subspherical particles of crystallized or partially crystallized liquid silicates that constitute large-volume fractions of most chondritic meteorites.

Composition, petrology, and chondrule‐matrix complementarity of the recently discovered Jbilet Winselwan CM2 chondrite [PDF]
Meteoritics and Planetary Science, 2018 Jbilet Winselwan (JW) is a recently found CM2 chondrite breccia containing two lithologies. A study of 508 chondrules provides the first statistically reliable size distribution for CM chondrite chondrules, which is about log normal with a mean chondrule
