Spinel in CV chondrules: Investigating precursor legacy and chondrule thermal histories

Meteoritics & Planetary Science, 2022
In carbonaceous chondrites, Mg‐spinel (MgAl2O4) grains are ubiquitous in refractory inclusions but rarely reported in chondrules, where they may correspond to minerals either (i) inherited from chondrule precursors or (ii) crystallized from chondrule ...

Potassium isotope systematics of the LL4 chondrite Hamlet: Implications for chondrule formation and alteration

Meteoritics and Planetary Science, 2020
Here, we apply recently developed high‐precision K isotope analyses to individual components of the LL4 chondrite Hamlet in order to investigate key processes which occurred during chondrite formation. The K isotopic compositions of all Hamlet chondrules

Chondrule sizes within the CM carbonaceous chondrites and measurement methodologies

Meteoritics & Planetary Science
The sizes of chondrules are a valuable tool for understanding relationships between meteorite groups and the affinity of ungrouped chondrites, documenting temporal/spatial variability in the solar nebula, and exploring the effects of parent body ...

The Spatial Origin of Chondrules in Individual Chondrites: Constraints from Modeling Chondrule Mixing

Astrophysical Journal, 2018
Chondrules are a major component of chondritic meteorites and potentially populated the entire protoplanetary disk before planet formation. Chondrules provide insights into the physical and chemical evolution of the protoplanetary disk.
