WebThey are the oldest known rocks—their components formed during the birth of the solar system ca. 4,567 Ma—and their abundances of nonvolatile elements are close to those in the solar photosphere. Chondrites are broadly ultramafic in composition, consisting largely of iron, magnesium, silicon, and oxygen. WebSep 20, 2005 · Chondrites are constructed from chondrules, the igneous products of transient heating events, and Ca–Al-rich refractory inclusions (CAIs). These high-temperature components are embedded in a volatile-rich, fine-grained, mineralogically complex matrix, which is a host for presolar grains. WebJan 1, 2024 · The major chondrite classes shown in Fig. 2 are carbonaceous chondrites with CI, CM, CO, and CV groups; ordinary chondrites with H, L, and LL groups; and enstatite chondrites with EH and EL groups. These are the most populated chondrite groups (e.g., Krot et al. 2003). The element ratios plotted in Fig. 2 are representative of different … check my junk mail folder windows 10
