Abstract— We measured the concentrations of 10 Be, 26 Al, 36 Cl, 41 Ca and 14 C in the metal and/or stone fractions of 27 Antarctic chondrites from Frontier Mountain (FRO), including two large H‐chondrite showers. To estimate the pre‐atmospheric size of the two showers, we determined the contributio...
