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 …

Renazzo-type carbonaceous (CR) chondrites are distinct from most other chondrites in
having younger chondrule 26 Al-26 Mg ages, but the significance of these ages and whether …

Chondrules from unequilibrated ordinary chondrites are among the oldest Solar system
materials and preserve mineralogical, chemical and isotopic signatures that link them to …

Chondrules may have played a critical role in the earliest stages of planet formation by
mediating the accumulation of dust into planetesimals. However, the origin of chondrules …

Whole rock Δ 17 O and nucleosynthetic isotopic variations for chromium, titanium, nickel,
and molybdenum in meteorites define two isotopically distinct populations: carbonaceous …

The systematic isotopic difference between refractory inclusions and chondrules, particularly
for oxygen, has long indicated an isotopic evolution of the solar protoplanetary disk …

Chondrules from different chondrite groups show characteristic properties, including
abundances of different chondrule textural types, chondrule sizes, oxygen isotope …

Isotopic anomalies in chondrules hold important clues about the dynamics of mixing and
transport processes in the solar accretion disk. The meaning of these anomalies is debated …

FeO-poor (type I) porphyritic chondrules formed by incomplete melting of solid dust
precursors via a yet-elusive mechanism. Two settings are generally considered for their …

Dynamic models of the protoplanetary disk indicate there should be large-scale material
transport in and out of the inner Solar System, but direct evidence for such transport is …
