Refractory inclusions in carbonaceous chondrites: Records of early solar system processes
AN Krot - Meteoritics & Planetary Science, 2019 - Wiley Online Library
Chondrites consist of three major components: refractory inclusions (Ca, Al‐rich inclusions
[CAI s] and amoeboid olivine aggregates), chondrules, and matrix. Here, I summarize recent …

Chondrule properties and formation conditions
Chondrules are iconic sub-millimeter spheroids representing the most abundant high-
temperature dust formed during the evolution of the circumsolar disk. Chondrules have been …

Chondrules reveal large-scale outward transport of inner Solar System materials in the protoplanetary disk
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 …

High precision 26Al-26Mg chronology of chondrules in unequilibrated ordinary chondrites: evidence for restricted formation ages
Chondrules in ordinary chondrites are considered to form in high density environments,
