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

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

We have studied porphyritic olivine-rich chondrules of the carbonaceous chondrite Kaba
(CV3) by combined high-resolution X-ray mapping, quantitative electron microprobe …

We report microscopic, cathodoluminescence, chemical, and O isotopic measurements of
FeO‐poor isolated olivine grains (IOG) in the carbonaceous chondrites Allende (CV3) …

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 …

Volatile lithophile elements are depleted in the different planetary materials to various
degrees, but the origin of these depletions is still debated. Stable isotopes of moderately …

The instrumental bias (here expressed as bias*, the difference relative to San Carlos Olivine,
SC-Ol) of oxygen isotopes in secondary ion mass spectrometry (SIMS) analyses of olivine …

A coordinated study of the petrology, mineral chemistry, and bulk chemical and isotopic
composition of the five ungrouped carbonaceous chondrites Coolidge, Loongana 001, Los …

Oxygen-isotope studies of carbonaceous chondrite chondrules are of pivotal importance for
understanding of the evolution of the solar protoplanetary disk. It has been previously …

Ferromagnesian chondrules present a remarkable dichotomy between reduced (type I) and
oxidized (type II) varieties. How these formed, and how they may be related remains …
