Episodicity of Mesozoic terrane accretion along the Pacific margin of Gondwana: implications for superplume-plate interactions

A review of evidence for deformation and terrane accretion on the Late Triassic-Early Jurassic margins of Pangaea and the mid-Cretaceous margins of the palaeo-Pacific ocean shows that deformation was global and synchronous with probable superplume events. Late Triassic-Early Jurassic deformation appears to be concentrated in the period 202–197 Ma and was coeval with eruption of the Central Atlantic Magmatic Province, onset of Pangaea break-up, a period of extended normal magnetic polarity and a major mass extinction event, all possible expressions of a superplume event. Mid-Cretaceous deformation occurred in two brief periods, the first from approximately 116 Ma to 110 Ma in the west palaeo-Pacific and the second from roughly 105 Ma to 99 Ma in the east palaeo-Pacific, with both events possibly represented in northeast Siberia. This deformation was coeval with eruption of major oceanic plateaux, core-complex formation and rifting of New Zealand from Gondwana, the Cretaceous normal polarity epoch, and a major radiation of flowering plants and several animal groups, all linked with the mid-Cretaceous superplume event. A simple unifying mechanism is presented suggesting that large continental or oceanic plates, when impacted by a superplume, tend to break-up/reorganize, associated with gravitational spreading away from a broad, thermally generated topographic high and with a resulting short-lived pulse of plate-marginal deformation and terrane accretion.

“…Initiation of granitoid magmatism appears to coincide with a significant oceanic plate reorganization, probably from old to young plates; subducted oceanic plates and their ages are based on Maruyama (1997). Early Cretaceous magmatism and hypothetical "Amur Basin" are considered to have been generated under a Sundastyle tectonic environment (Sato et al, 2002(Sato et al, , 2004b.…”

“…This could be a result of displacement of the Kitakami area toward north from its position during magmatism because the tectonic regime in the Early Cretaceous is characterized by the highly oblique convergence of the paleo-Pacific plate and East Asia (e.g., Maruyama and Seno, 1986;Sato et al, 2004b). Sato et al (2002) proposed a Sundastyle tectonic model for the genesis of the KhinganOkhotsk Volcano-Plutonic Belt. The Kitakami area may also have been involved in this tectonic regime.…”

“…1). The igneous regions within Russia are divided into two belts: the Khingan-Okhotsk Belt and Sikhote-Alin Belt (Sato et al, 2002). These two belts are considered to be juxtaposed arcs with different geotectonic histories, showing an unusually broad distribution of igneous rocks (Sato et al, 2004b).…”

Lermontovskoe Tungsten Skarn Deposit: the Oldest Mineralization in the Sikhote-Alin Orogen, Far East Russia

. Lermontovskoe tungsten skarn deposit in central Sikhote‐Alin is concluded to have formed at 132 Ma in the Early Cretaceous, based on K‐Ar age data for muscovite concentrates from high‐grade scheelite ore and greisenized granite. Late Paleozoic limestone in Jurassic ‐ early Early Cretaceous accretionary complexes was replaced during hydrothermal activity related to the Lermontovskoe granodiorite stock of reduced type. The ores, characterized by Mo‐poor scheelite and Fe3+‐ poor mineral assemblages, indicate that this deposit is a reduced‐type tungsten skarn (Sato, 1980, 1982), in accordance with the reduced nature of the granodiorite stock. The Lermontovskoe deposit, the oldest mineralization so far known in the Sikhote‐Alin orogen, formed in the initial stage of Early Cretaceous felsic magmatism. The magmatism began shortly after the accretionary tectonics ceased, suggesting an abrupt change of subduction system. Style of the Early Cretaceous magmatism and mineralization is significantly different between central Sikhote‐Alin and Northeast Japan; reduced‐type and oxidized‐type, respectively. The different styles may reflect different tectonic environments; compressional and extensional, respectively. These two areas, which were closer together before the opening of the Japan Sea in the Miocene, may have been juxtaposed under a transpressional tectonic regime after the magmatism.

Provenance of Cretaceous trench slope sediments from the Mesozoic Wandashan Orogen, NE China: Implications for determining ancient drainage systems and tectonics of the Paleo-Pacific

The Wandashan Orogen of NE China is a typical accretionary orogen related to Paleo-Pacific subduction. The Raohe Complex, as a major part of the orogen, consists of mid-Triassic to mid-Jurassic radiolarian chert and intraoceanic igneous rocks in an accretionary prism overlain by weakly sheared terrestrial-sourced clastic trench slope sediments. Sensitive high-resolution ion microprobe U-Pb dating and LA-MC-ICPMS Hf isotopic analysis of detrital zircons from the terrestrial-sourced Yongfuqiao Formation sandstone show that most zircons are Phanerozoic (90%): 140-150 Ma (10%), 180-220 Ma (25%), 240-270 Ma (15%), 300-360 Ma (15%), 391-395 Ma (3%), and 450-540 Ma (20%), whereas 10% are Precambrian in age. About 90% of the zircons have ε Hf (t) values ranging from +11.1 to À12.8. This suggests that the major provenance of the trench slope sediments was from the adjacent eastern segment of the Central Asian Orogenic Belt and the Jiamusi Block. The age of the Yongfuqiao Formation is constrained to the earliest Cretaceous, which represents the accretion time of the mid-Triassic to mid-Jurassic oceanic complexes. When compared with the Mino Complex in Japan and the Tananao Complex in Taiwan, three different provenances are identified suggesting three ancient drainage systems which transported sediments from NE China, North China, and South China to the Paleo-Pacific subduction-accretion system.
