Abstract
En 中文
• Early- and late-formed planetesimals formed from the same mix of dust components. • Many differentiated meteorites share an isotopic signature with CR chondrites. • The CR reservoir was established early and remained isolated throughout disk history. • CI chondrites are the only CC type not represented in differentiated meteorites. • CI chondrites formed late by photoevaporation and/or in a distinct disk reservoir.
