Cosmogenic Nuclides in Metal and Stone Separates of an Antarctic L5/LL5 Chondrite Shower with a Large Pre-Atmospheric Size: QUE 90201Based on cosmogenic radionuclides in stone and metal fractions, we identified six members of a large Antarctic L5/LL5 chondrite shower. The radionuclides suggest a pre-atmospheric radius of 100-200 cm and a cosmic-ray exposure age of at least 5 Myr. Additional information is contained in the original extended abstract.
