Abstract
⺠A diorite pluton and widely distributed mafic dykes occur in the Fosdick Mountains. ⺠The mafic intrusive rocks have Cretaceous crystallization ages ranging from ca 113 to 97 Ma. ⺠They are medium- to high-K-series calc-alkaline rocks with basic-intermediate composition. ⺠The trace element and Sr-Nd isotope data suggest melting of metasomatized sub-arc mantle sources.
