Title: Nd in Island Arc and Continental Volcanic Rocks
Abstract: Measurements of initial ^(143)Nd/^(144)Nd (expressed as e_I ^(CHUR)) and ^(87)Sr/^(86)Sr were made on an andesite
(BMR-1) and two dacites (BMR-3,5) from the New
Britain volcanic arc to compare them with oceanic
basalts and continental volcanics, and to evaluate
models of the genesis of island arc magmas
and their role in the growth of continental crust.
In addition, continental ultrapotassic volcanics
have been measured to determine if they are
derived from a special magma source.
