Abstract
New abundance determinations for presolar diamond, SiC, and graphite in CM2 chondrites are presented and used to infer initial abundances in primitive solar-system material. Modifications of initial abundances reflect early-solar-system processes. Additional information is contained in the original extended abstract.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
