Evidence for Post-impact Plume Origin of Porphyritic Chondrules in Isheyevo (ch/cb) and Ch Carbonaceous Chondrites

It is suggested metal-rich carbonaceous chondrites (CCs), CB, CH and Isheyevo, contain various proportions of chondritic components (CAIs, chondrules, metal) formed (i) by melting, evaporation, and condensation processes in an impact plume resulted from a planetary-scale collision, and (ii) by thermal processing of dust aggregates in the protoplanetary disk (PPD) [1−4]. The impact-plume product...

Lithium Isotopic Analyses of Chondrites and Chondrules

Introduction: Light stable isotopes provide insights and constraints on nebular and parent body processes. Lithium isotope studies of chondrites offer such potential, with some specifically unique aspects. Lithium is monovalent, the lightest of nongaseous elements, it has a 15% mass difference between its 2 isotopes (Li and Li), it is fluid mobile, and it is one of the fastest diffusing element...

Origins of Chondrules in the Metal-rich Carbonaceous Chondrites

Introduction: The metal-rich CH and CB chondrites are among the most primitive (unmetamorphosed, unaltered), but controversial meteorites: both nebular and asteroidal models have been proposed to explain the origins of their components [1-14]. In addition to porphyritic chondrules and rare refractory inclusions, the CHs contain a high abunbance (~20 vol%) of metal and dominant cryptocrystalline...
