Young volcanic rocks from different sections of the Aleutian Islands-Alaska Peninsula Arc have been measured for ^(87)Sr/^(86)Sr, ^(143)Nd/^(144)Nd and some trace elements. We found the ^(143)Nd/^(144)Nd to be highly restricted in range (ɛ_(Nd)=6 to 7) and low as compared to midocean ridge basalts...
