“…From late Paleozoic through Paleogene times, the convergent margin appears to have undergone progressive addition of accretionary complexes to the fore‐arc (Fig. ), which, at least during the Cretaceous–Paleogene, was a consequence of weak coupling of the subducted and overriding plates and consequent oceanward trench retreat (Sagong et al , ; Chough & Sohn, ; Imaoka et al , ; Kim et al , ). Miocene Japan has been cited as an example of Mariana‐type subduction, characterized by weak inter‐plate coupling, steep subduction, extension, and back‐arc basin opening (Uyeda & Kanamori, ).…”

“…In addition to oxidized magmatic conditions, adakite‐like intrusions, characterized by high Sr/Y, are widely promoted as hallmarks of arc segments that are especially fertile for porphyry Cu genesis (Loucks, ). High Sr/Y – commonly ascribed to suppression of plagioclase fractionation due to the elevated magmatic water contents that are conducive to porphyry Cu formation (Richards, ) – are reported from a few Early Cretaceous intrusions throughout Japan (Kamei, ; Takahashi et al , ; Tsuchiya et al , , ; Ishihara & Chappell, ) and several Quaternary volcanoes in SW Japan (Mahony et al , ; Shibata et al , , and references therein), but apparently not from post‐Jurassic magmatic rocks in South Korea (Kim et al , ). Although most of the Early Cretaceous intrusions are barren, several in the Kitakami belt, including that alongside the Kamaishi Cu‐Fe skarn (Fig.…”

This analysis concludes that there is little realistic likelihood of discovering large, high‐grade porphyry Cu deposits in Japan and South Korea because of an unusual combination of geological factors. First, weak inter‐plate coupling, trench retreat, and extension – a tectonic regime unfavorable for porphyry Cu formation – appears to have characterized the convergent margin during much of Cretaceous through Neogene time. Second, Cretaceous through Quaternary magmatism involved widespread ash‐flow caldera development, a volcanic style that suppresses porphyry Cu formation because the all‐important Cu‐bearing magmatic fluids – if present – would be explosively discharged during silicic ignimbrite eruption and lost to the atmosphere. Third, due to the trench retreat, crustal profiles beneath Japan are dominated by accretionary complexes containing chemically reduced lithologies, which decrease the redox state of subduction‐related magmas during their ascent. The most reduced intrusions belong to the ilmenite‐series, which may lock up chalcophile elements at depth and produce magmatic fluids that are incapable of transporting the Cu required for significant porphyry deposit formation. Fourth, many of the caldera‐related magmatic rocks, including the principal intrusions, are not only derived by partial melting of reduced crust but are commonly also highly fractionated; hence, any associated mineralization tends to be Mo ± W‐rich rather than Cu dominated. Fifth, intrusive rocks with high Sr/Y, typical of hydrous magmas responsible for porphyry Cu belts worldwide, appear to be present only locally. Sixth, two important magmatic and metallogenic tracts in Japan, the Kuroko‐bearing Green Tuff belt and Kitami low‐sulfidation epithermal Au region, are characterized by bimodal magmatism, which worldwide is compositionally unsuited to porphyry Cu generation. Seventh, the Pliocene‐Quaternary andesitic–dacitic volcanoes that could be the surface expressions of porphyry Cu systems are mostly too shallowly eroded to reveal underlying deposits should they exist. Consequently, few magmatic suites in Japan and South Korea provide propitious environments for porphyry Cu exploration, with the last hope believed to lie at depth below late Miocene–Pliocene advanced argillic lithocaps, several of which contain relatively minor high‐sulfidation epithermal Au mineralization. However, even there, the reduced crust may have militated against effective Cu transport into the porphyry environment. The magmatic and metallogenic factors that downgrade the porphyry Cu potential of Japan and South Korea are believed to be equally applicable to other subduction‐related magmatic arc segments worldwide.

Abstract:We report an Early Cretaceous zircon U-Pb age (113.9±1.2 Ma) for the Heuksan-do granite located about 90km from Mokpo offcoast of the southwestern Korean peninsula. At this Aptian/Albian boundary, widespread igneous activities occurred not only in the Korean peninsula but also in the eastern China and Japan. We raise the possibility that the flat-slab subduction and delamination triggered such an episodic igneous activity over the large areas of East Asia.

Response of provenance transition of Middle Jurassic–Early Cretaceous sediments to tectonic domain transformation in the North Yellow Sea Basin, Eastern North China Craton

In the Late Mesozoic, the Eastern North China Craton changed from being controlled by the Palaeo‐Asian tectonic domain to the marginal Pacific tectonic domain. The Eastern North China Craton transformed the E–W compression to NNE–SSW extensional tectonics under the influence of two tectonic domain transformations. However, the timing of the transformation of the tectonic domains remains controversial. The North Yellow Sea Basin is located in an important position in the Eastern North China Craton at the junction of the Pacific and Eurasian plates and is controlled by two tectonic domains. Therefore, the sediments in the basin are faithful records of the transformation of the two tectonic domains. Based on the latest and high‐precision detrital zircon U–Pb dating data, sandstone modal analysis, and elemental geochemical analysis in the North Yellow Sea Basin combined with regional tectonic, palaeontological, and palaeoclimatic evidence, this paper discusses the provenance from the Middle Jurassic to Early Cretaceous, which responds to the Late Mesozoic tectonic domain transformation in the Eastern North China Craton, and provides important evidence of provenance in the North Yellow Sea Basin to determine the time of tectonic domain transformation. These results suggest that the source rocks of sediments in the North Yellow Sea Basin have changed from ancient sediments (ancient craton/recycle orogenic belt) in the Middle Jurassic to Late Jurassic, to felsic igneous rocks in the Early Cretaceous. The peak of zircon U–Pb ages changed from 234, 1,842, and 2,429 Ma in the Late Jurassic to 217 and 1,871 Ma in the Early Cretaceous. The provenance changed from the Sulu Orogenic Belt and Precambrian basement of the Jiaodong Peninsula in the Late Jurassic, to the igneous rocks and Precambrian basement of the Liaodong Peninsula and Korean Peninsula in the Early Cretaceous. The provenance direction of the sediments changed from south‐west in the Late Jurassic to the north and south‐east in the Early Cretaceous. The tectonic setting of the basin changed from compression to extension. The changes in the peaks of zircon U–Pb age, characteristics of the source rocks, provenance direction, and basin tectonic setting in the Middle Jurassic to Early Cretaceous in the North Yellow Sea Basin are a response to the change from E–W compression to NNE–SSW extensional tectonics caused by the transformation of two tectonic domains. In the Early Cretaceous, the Eastern North China Craton completed the transformation of two tectonic domains that were influenced and controlled by the marginal Pacific tectonic domain.
