General tectonic map of the Philippine island arc system (modified from Rangin 1991; Yumul et al. 2008a, b). The continental Palawan-Mindoro Microcontinental Block and island arc Philippine Mobile Belt (PMB) characterize the Philippine Archipelago. The mentioned islands are represented by green labels: LZN = Luzon, MNDR = Mindoro, PLW = Palawan, PNY = Panay, NGR = Negros, SMR = Samar, LYT = Leyte, MNDN = Mindanao. Red areas represent Cretaceous (island arc) metamorphic zones, while blue areas correspond to pre-Cretaceous (continental) metamorphic regions (modified from MGB 2010). The inset map shows the location of the Philippines relative to Southeast Asia. The traces of plate boundaries are from USGS (2019) (https://www.usgs.gov/media/files/plate-boundaries-kmz-file)
