The significance of the carbonaceous chondrites abundances - Introductory report
Abstract
The paper discusses the significance of the carbonaceous chondrite (CC) elemental abundances in terms of abundances in the primitive solar nebula. The abundances are considered in terms of: (1) the possibility of volatile element enrichments and depletions in CC matrices, (2) the existence of a unique matrix composition among C1's, C2's, and C3's based on recent observations of CC matrices, (3) abundance similarities with solar photosphere, and (4) the continuity of elemental abundances beyond Fe. It was confirmed that the CC abundances are highly significant for refractory elements, and that C1 abundances are probably the best guide to the abundances of volatiles. The high abundances of Li, Be, and B in meteorites compared with sun and stars may be the evidence for early solar irradiation.
