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

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

Ordinary and carbonaceous chondrites of the lowest petrologic types were surveyed by X‐
ray mapping techniques. A variety of metamorphic effects were noted and subjected to …

We have developed a nebular condensation model and a computational routine that
potentially can account for the unequilibrated mineral assemblages in chondritic meteorites …

High-precision oxygen three-isotope measurements of olivine and pyroxene were
performed on 33 chondrules in the Yamato 81020 CO3. 0 chondrite by secondary ion mass …

The mineralogy and petrology of FeO-poor, porphyritic, pyroxene-and olivine-rich
chondrules in the Semarkona (LL3. 0) chondrite are described in detail. In an extension of …

To better understand the formation conditions of type-I and type-II chondrules in the
Renazzo-like carbonaceous (CR) chondrites, an in situ major-and minor-element and O …

CHONDRULES are millimetre-sized spheroidal bodies composed mainly of olivine and
orthopyroxene, which comprise the dominant fraction of most chondritic meteorites. They are …

In a search for evidence of evaporation during chondrule formation, the mesostases of 11
Bishunpur chondrules and melt inclusions in olivine phenocrysts in 7 of them have been …

The stable potassium isotopic ratios (41 K/39 K) of Earth and Mars have been interpreted to
reflect either nucleosynthetic isotope anomalies or volatility-driven K depletion. Chondrites …
