- •
Fine-grained dust rims in primitive meteorites contain abundant stardust grains.
- •
Integrated abundances over all samples show variations between rims and matrix.
- •
This suggests different alteration pathways for rims and matrix.
- •
These observations indicate a nebular origin for the fine-grained rims.
