Abstract— We determined terrestrial ages of ordinary chondrites from the Lewis Cliff stranding area, East Antarctica, on the basis of the concentrations of cosmogenic 10 Be ( t ½ = 1.51 Ma), 26 Al ( t ½ = 0.705 Ma), and 36 Cl ( t ½ = 0.301 Ma). After an initial 26 Al γ‐ray survey of 91 meteorites su...
