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) …

[HTML][HTML] Magnesium and 54Cr isotope compositions of carbonaceous chondrite chondrules–Insights into early disk processes

MB Olsen, D Wielandt, M Schiller… - … et cosmochimica acta, 2016 - Elsevier
We report on the petrology, magnesium isotopes and mass-independent 54 Cr/52 Cr

Evolution of protoplanetary disk inferred from 26Al chronology of individual chondrules

NT Kita, T Ushikubo - Meteoritics & Planetary Science, 2012 - Wiley Online Library
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 …

The CR chondrite clan: Implications for early solar system processes

AN Krot, A Meibom, MK Weisberg… - Meteoritics & Planetary …, 2002 - Wiley Online Library
In this paper, we review the mineralogy and chemistry of calcium‐aluminum‐rich inclusions
(CAIs), chondrules, FeNi‐metal, and fine‐grained materials of the CR chondrite clan …

Outward migration of chondrule fragments in the early Solar System: O-isotopic evidence for rocky material crossing the Jupiter Gap?

DL Schrader, K Nagashima, J Davidson… - … et Cosmochimica Acta, 2020 - Elsevier
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 …

J Bollard, N Kawasaki, N Sakamoto, M Olsen… - … et Cosmochimica Acta, 2019 - Elsevier
Chondrites are fragments of asteroids that avoided melting and, thus, provide a record of the
material that accreted to form protoplanets. The dominant constituent of chondrites are …

A temporal shift of chondrule generation from the inner to outer Solar System inferred from oxygen isotopes and Al-Mg chronology of chondrules from primitive CM and …
