Western Northern Luzon Isotopic Evidence of Transition from Proto-South China Sea to South China Sea Fossil Ridge Subduction

Temporal geochemical comparisons are conducted for representative magmatism from western Northern Luzon to reconstruct the Cenozoic tectonics. Oligo‐Pleistocene magmas from western Northern Luzon display elemental and Sr‐Nd‐Hf‐Pb‐O isotope geochemistry similar to intraoceanic arc magmatism, consiste...
