Young chondrules in CB chondrites from a giant impact in the early Solar System

Krot, Alexander; Amelin, Yuri; Cassen, Patrick; Meibom, Anders

Description

Chondrules, which are the major constituent of chondritic meteorites, are believed to have formed during brief, localized, repetitive melting of dust (probably caused by shock waves) in the protoplanetary disk around the early Sun. The ages of primitive chondrules in chondritic meteorites indicate that their formation started shortly after that of the calcium-aluminium-rich inclusions (4,567.2 ± 0.7 Myr ago) and lasted for about 3 Myr, which is consistent with the dissipation timescale for...[Show more]
