摘要: Carbonaceous chondrites are meteoritic fragments of asteroids that avoided the geological reprocessing larger planets and allow laboratory probing early solar-nebula materials. Among these, Renazzo-type (CR) found in Antarctica appear remarkably pristine distinguished by abundant organic materials water-soluble molecules such as amino acids ammonia. We present a comprehensive analysis composition selected CR meteorites different petrographic classification compare compounds’ abundance distribution they may relate to asteroidal aqueous processing concomitant evolution mineral phases. several compounds sugar alcohols fully represented stones with no or minimal water exposure indicating formation that, if solar, preceded parent body processes. The most CRs also revealed natal enantiomeric excesses (ee) up 60%, much than ever recorded. However, alteration appears affect soluble abundances, particular some diastereomeric gauge its extent consequent racemization their ee.
