Age and geochemical constraints on ridge subduction for igneous rocks of the eastern Chugach Mountains, Alaska
Igneous rocks in the Chugach metamorphic complex (CMC) of southern Alaska form part of the Sanak-Baranof belt, a series of forearc plutons believed to have been formed by subduction of a spreading ridge. Trace element and Nd-Sr isotopic data suggest that magmas were derived from the mixing of two so...
