Geochemistry of a Pliocene-Pleistocene oceanic-arc plutonic complex, Guadalcanal

Journal Article


Abstract


  • The Koloula Igneous Complex, on the island of Guadalcanal, consists of a low-K calc-alkaline sequence of 26 different intrusive phases. The major intrusions are characterized by K/Rb>400, Rb/Sr<0.06, �� 18O of 5.7 to 7.2 and uniform 87Sr/86Sr of 0.70372. This article presents the first data describing oxygen and strontium isotopic behaviour within a plutonic suite that formed by crystal fractionation. �� 1982 Nature Publishing Group.
