“…The radiolarian fauna is similar to low‐latitude faunas found in ocean drilling in the central North Pacific. Dimalanta et al (2020) suggest that the Huatung Basin may be a remnant of Mesozoic proto‐Philippine Sea Plate based on geochemical correlation of allochthonous crust‐mantle sequences along the eastern edge of the Philippines.…”

 Rapidly deforming wedge-top Chimei Canyon/Fan on Philippine Sea plate shows distinctive wide-canyon morphology and rapid fan evolution  Chimei Fan gives 0-2 Ma record of Taiwan arc-continent collision based on seismic stratigraphy and integration with proximal onshore record  The Taiwan-derived depocenter shifted ~1Ma from proximal forearc basin to east of arc due to ~60 km thrust-belt convergence and over filling

“…The northern East Asian Sea coined by these authors could also refer to the ‘proto‐Philippine Sea’ plate. However, in this study, the proto‐Philippine Sea plate was located at lower latitudes, specifically a few degrees north of the equator down to 15°S based on recent palaeomagnetic and geochemical data (Balmater et al , 2015; Guotana, et al , 2017; Dimalanta et al , 2019). The Cenozoic basin of Pubellier et al (2003) corresponds to the Philippine Sea Plate which developed at the northern margin of Australia (Pubellier et al , 2003).…”

“…The Mesozoic basin postulated by Pubellier et al (2003) could be the proto‐Philippine Sea plate, described by Zahirovic et al (2014) as a back‐arc basin formed through the slab roll back of the palaeo‐Pacific plate which opened between 155 and 115 Ma. Dimalanta et al (2019) suggested that the proto‐Philippine Sea Plate could have been part of a larger Mesozoic oceanic basin associated with the Mesotethys and the palaeo‐Pacific plate that subducted towards the Eurasian‐Sundaland continent. Obducted sections of oceanic crusts generated from the proto‐Philippine Sea plate could be observed at the central and eastern parts of the Philippine Archipelago (Balmater et al , 2015; Guotana, et al , 2017; Dimalanta et al , 2019).…”

The Late Cretaceous Pandan Formation in Cebu Island is one of the oldest sedimentary units in the Central Philippines. The inconsistencies in geological descriptions and interpretation of the depositional environment of the Pandan Formation complicated efforts to determine the origin and tectonic history of the basement of Cebu Island. This study therefore looks into the petrological and geochemical characteristics of the Pandan Formation and their implications for the tectonic development of the Philippine Arc during the late Mesozoic. Petrographic analyses indicate significant contribution from mafic sources with additional inputs from felsic rocks, siliciclastics and metamorphic sources. Enrichment of detrital quartz from felsic volcanic and plutonic rocks, as well as from siliciclastic and metamorphic sources, has shifted the SiO 2 composition of the Pandan clastics from a mafic to a more intermediate source. Whole-rock geochemical analyses revealed low SiO 2 /Al 2 O 3 = 4.21, low K 2 O/Na 2 O = 1.16, low Th/Sc = 0.13, low Th/U = 2.78, high La/Th = 4.51, significantly low REEs = ca 76.45 ppm and low La N /Yb N = 4.28. A slight negative chondrite-normalized Eu/Eu* (0.91) anomaly and significantly high PAAS-normalized positive Eu/Eu* (1.39) values are consistent with derivation from a young undissected magmatic arc terrane. Tectonic discrimination diagrams suggest formation in an oceanic island arc to active margin/collision zone modelled to be located at the oceanic leading edge of Australia. Rapid uplift and erosion of the magmatic arc and older allochthonous blocks gave way to the rapid deposition of the Pandan Formation in the Late Cretaceous at the subequatorial region.
