Western Northern Luzon Isotopic Evidence of Transition from Proto-South China Sea to South China Sea Fossil Ridge Subduction
Text S1-3 present detailed sample description, analytical methods (Text S1), discussion on emplacement age of the Central Cordillera diorite complex (Text S2) and evaluation of post-magmatic alteration (Text S3) for the western Northern Luzon igneous rocks. The supporting figures provide 1) spatial variation of Sr isotope composition, 2) microphotographs, 3) zircon CL images, 4) plots of K2O and Sr-Nd-Pb isotope composition versus LOI, and 5) correlations between Sr-Nd isotope composition and silica for the western Northern Luzon igneous rocks. The supporting tables provide original data used in the main article.
