Cosmogenic Radionuclides in Four Paired Antarctic L/LL Chondrites Indicate Similar Cosmic-Ray Exposure Age as Chelyabinsk LL Chondrite
Abstract
Cosmogenic radionuclides in 4 L/LL chondrites from Wisconsin Range, Antarctica indicate they are paired fragments. Their CRE age of ~1.7 Ma overlaps with the age of the large Chelyabinsk LL chondrite, suggesting a common ejection event.
