Post-collisional potassic magmatism with elevated Rb concentrations in the Muria back-arc, Central Java: constraints from Rb-Hf-Ta systematics and mantle source interactions

The Muria volcanic complex (MVC), located in the rear-arc of Central Java, Indonesia, represents an unusual potassic-alkaline magmatic system within an otherwise calc-alkaline subduction-dominated arc. This study integrates compiled geochemical datasets, including major oxides, t...
