“…However, due to the poor preservation of seafloor spreading histories, Zahirovic et al () proposed an alternative scenario, where East Java, West Sulawesi, and eastern Borneo originate from the Argo Abyssal Plain on the NW Shelf of Australia, which is adopted in Zahirovic et al (). In addition, the Sepik and Philippine Arcs are attached to New Guinea before moving northward in Zahirovic et al (), and the north margin was an active margin character, which is consistent with the age and geochemistry of the Central Ophiolite Belt on New Guinea (Permana, ) and also the magmatic and paleomagnetic history of the Philippine Arc (Balmater et al, ; Deng et al, ). Another major change in Zahirovic et al () is that the peak of (ultra) high‐pressure metamorphics in the Luk‐Ulo suture zone on East Java at ~115 Ma is reinterpreted to be the onset of subduction of the Woyla Sea backarc, rather than the previously interpreted collision of the East Java, West Sulawesi, and the Woyla intraoceanic arc in Müller, Seton, et al ().…”

Some changes in the topography of eastern China since Late Jurassic times cannot be well explained by lithospheric deformation. Here we analyze global mantle flow models to investigate how mantle-driven long-wavelength topography may have contributed to shaping the surface topography of eastern China. Paleodrainage directions suggest that a southward tilted topography once existed in eastern north China in the latest Jurassic Period, which is different from that at present day (southeastward tilting). Our model dynamic topography reveals a southward tilting topography between 160 and 150 Ma, followed by southeastward tilting and rapid subsidence, which is compatible with paleodrainage directions and tectonic subsidence of the Ordos Basin. The Cretaceous anomalous subsidence of the Songliao and North Yellow Sea basins, as well as the Cenozoic anomalous subsidence of the East China Sea Shelf Basin, can also be explained by dynamic topography. An apatite fission track study in the Taihang Mountains reveals four stages of evolution: Late Jurassic fast unroofing, Cretaceous slow unroofing, early Cenozoic fast unroofing, and late Cenozoic slow unroofing. We propose that mantle flow influenced this surface unroofing because the model predicts Late Jurassic dynamic uplift, Cretaceous dynamic subsidence, early Cenozoic dynamic uplift, and late Cenozoic dynamic subsidence. Apatite fission track data from northern south China are also in reasonable agreement with predicted dynamic topography between 80 and 30 Ma. The spatial and temporal agreement between geological observations and model dynamic topography indicates that mantle flow has had a significant influence in shaping the surface topography of eastern China.

“…The termination of the back‐arc spreading of the proto‐Philippine Sea Plate at 115 Ma was due to the collision of continental fragments from Sulawesi with an intra‐oceanic subduction zone (Zahirovic et al , 2014). This intra‐oceanic subduction system corresponds to the recognized Early Cretaceous volcanic flow deposits in Cebu Island (Deng et al , 2015). This event is herein construed as the onset of the collision of the proto‐Philippine arc with the East Philippine‐Daito arc leading to the Late Mesozoic growth of the Philippine Mobile Belt.…”

“…The Cansi Volcanics contain interbeds of andesitic flows and breccias, conglomerates and greywackes. A recent study conducted by Deng et al (2015) revealed that Cebu Island's volcanic rocks (diabases, basalts‐basaltic andesites, pyroclastic rocks and porphyritic andesites) exposed in Kansi village in the Municipality of Asturias (Figure 2A) represent Early Cretaceous ( ca 126–117 Ma) arc volcanism in the Central Philippines. This age of arc volcanism is much earlier than the intrusion of the Lutopan Diorite dated 105 Ma by Wolfe (1995) and 102–109 Ma by Deng et al (2015).…”

The Depositional Record

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.

“…Estimations of the global length of continental arc chains in the Cretaceous by Cao et al () do not take into account the eastern Australia arc, adding possibly ~25% more than previously estimated, making it already the longest arc since at least 750 Ma. The Cretaceous circum‐Paleo‐Pacific continental arc almost encircled all global continents, leaving only a gap where the Paleo‐Pacific and Neo‐Tethys Oceans converged, forming the basement of the present Philippines archipelago (Deng et al, ; Metcalfe, ). This Cretaceous continental arc flare‐up influenced the tectonic evolution of the circum‐Pacific continents and was the main driving force for magmatism, exhumation, and sedimentation at both the plate margins and the continental interiors (Paterson et al, ; Pearson et al, ).…”

Continental Arc and Back‐Arc Migration in Eastern NE China: New Constraints on Cretaceous Paleo‐Pacific Subduction and Rollback

et al. 2018

Tectonic evolution models for the Cretaceous Russia Sikhote-Alin and eastern NE China continental margin and interior remain controversial. To understand the magmatic evolution over time and assess regional geodynamic processes, we sampled a diverse array of igneous rocks and employed zircon U-Pb dating, hornblende and plagioclase 40 Ar-39 Ar dating, whole-rock major and trace element analysis, and 87 Sr/ 86 Sr and 143 Nd/ 144 Nd isotopic analysis. The west Sikhote-Alin Pikeshan Formation volcanics and associated granites occurred at a peak of~118 Ma and are hosted by the Triassic-Jurassic accretionary complex. Their whole rock geochemistry shows that SiO 2 increased in a linear trend, Eu/Eu* values decreased from 0.91 to 0.38, and ε Nd (t) values decreased from +0.6 to À2.9, indicating magma mixing of a juvenile mantle wedge source and continental crust, consistent with a continental arc. The arc thickened over time with a felsic dike hosted in the Pikeshan granites showing depletion in heavy rare earth elements. The termination of the arc front is documented by the~107-Ma intermediate lamprophyre and felsic dikes with ε Nd (t) values of +4.5 to +1.1, indicating an increased mantle contribution over time. Lithospheric extension of the Jiamusi Block to the west occurred at~100 Ma, characterized by bimodal volcanism and composite dike emplacement, suggestive of asthenosphere upwelling. Based on the spatial and temporal distribution of these igneous rocks, the continental arc and intraplate magmatism migrated eastward contemporaneously. We favor a model invoking rollback of the subducting Paleo-Pacific slab affecting a long-lived continental arc.In the Early Cretaceous, the Russian Far East and NE China, Korea, and Japan, as well as the Chinese continental shelf, collectively constituted the eastern Asian continental margin before the opening of the marginal seas (Tang et al., 2016). The integrated continental margin was formed by Paleo-Pacific subduction SUN ET AL. 3893
