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 …

About 435 mineral species have been identified in meteorites including native elements,
metals and metallic alloys, carbides, nitrides and oxynitrides, phosphides, silicides, sulfides …

We present a model for the thermal processing of particles in shock waves typical of the
solar nebula. This shock model improves on existing models in that the dissociation and …

Chondrule textures depend on the extent of melting of the chondrule precursor material
when cooling starts. If viable nuclei remain in the melt, crystallization begins immediately …

▪ Abstract Chondrules are∼ 1-mm igneous droplets in primitive meteorites, and their
abundance suggests widespread melting in the protoplanetary disk. Chondrules with relict …

We review a number of constraints that have been placed on the formation of chondrules
and show how these can be used to test chondrule formation models. Four models in …

Millimeter‐scale rock particles called chondrules are the principal components of the most
common meteorites, chondrites. Hence, chondrules were arguably the most abundant …

The petrologic and geochemical properties of chondrules as well as results of experimental
studies provide strong constraints on chondrule-formation models. Nebular formation is …

We review chemical, mineralogical and isotopic properties of chondrules that can be used to
investigate chondrule origins. Although many interpretations of chondrule properties are …

We investigate the hypothesis that many chondrules are frozen droplets of spray from impact
plumes launched when thin‐shelled, largely molten planetesimals collided at low speed …
