The Geochemistry of The Neogene Halmahera Arc, Eastern Indonesia

The Geochemistry of the Neogene Halmahera Arc, Eastern Indonesia examines the major, trace, and rare earth element characteristics of Neogene volcanic and plutonic rocks from the Halmahera island arc in eastern Indonesia to constrain magma sources and tectonic setting. The study evaluates geochemical signatures indicative of subduction-related magmatism, including enrichment in large-ion lithop…
