“…The igneous activity of the Khingan-Okhotsk belt has been thought to have begun in the Barremian and lasted throughout the entire Late Cretaceous (Faure and Natal'in, 1992;Natal'in, 1993). In this case, the tin-rich Khingan-Okhotsk belt is not clearly discriminated in age from the northern Sikhote-Alin belt characterized by gold mineralization.…”

“…This massif is usually depicted as a single tectonic unit, but it may consist of several independent blocks although the time of amalgamation is a matter of debate (Natal'in, 1993). According to the geologic maps published by DALGEOLOGIA (1991) andVSEGEI (1992), the Bureya massif consists mainly of Paleozoic granitoids with lesser amount of Archean to Proterozoic metamorphic and granitic rocks and Proterozoic to Paleozoic sedimentary rocks.…”

“…In any case, the exposures around Khabarovsk City are extremely poor because the area is mostly covered by Cenozoic deposits of the Middle Amur Basin (Fig. 3), and the boundary between the Badzhal and Khabarovsk complexes is not clearly delineated (Natal'in, 1993). In this article, the Khabarovsk complex is defined as shown in Figures 3 and 4, to include both the Badzhal and Khabarovsk complexes by Natal'in (1993), in view of its contrasting lithology to the Amur complex described below.…”

Age of magmatism and tin mineralization in the Khingan-Okhotsk volcano-plutonic belt, including the Khingan, Badzhal and Komsomolsk tin fields, were reviewed in terms of tectonic history of the continental margin of East Asia. This belt consists mainly of felsic volcanic rocks and granitoids of the reduced type, being free of remarkable geomagnetic anomaly, in contrast with the northern Sikhote-Alin volcano-plutonic belt dominated by oxidized-type rocks and gold mineralization. The northern end of the Khingan-Okhotsk belt near the Sea of Okhotsk, accompanied by positive geomagnetic anomalies, may have been overprinted by magmatism of the Sikhote-Alin belt.Tin-associated magmatism in the Khingan-Okhotsk belt extending over 400 km occurred episodically in a short period (95±10 Ma) in the middle Cretaceous time, which is coeval with the accretion of the Kiselevka-Manoma complex, the youngest accretionary wedge in the eastern margin of the Khingan-Okhotsk accretionary terranes. The episodic magmatism is in contrast with the Cretaceous-Paleogene long-lasted magmatism in Sikhote-Alin, indicating the two belts are essentially different arcs, rather than juxtaposed arcs derived from a single arc. The tin-associated magmatism may have been caused by the subduction of a young and hot back-arc basin, which is inferred from oceanic plate stratigraphy of the coeval accretionary complex and its heavy mineral assemblage of immature volcanic arc provenance. The subduction of the young basin may have resulted in dominance of the reduced-type felsic magmas due to incorporation of carbonaceous sediments within the accretionary complex near the trench. Subsequently, the back-arc basin may have been closed by the oblique collision of the accretionary terranes in Sikhote-Alin, which was subjected to the Late Cretaceous to Paleogene magmatism related to another younger subduction system. These processes could have proceeded under transpressional tectonic regime due to oblique subduction of the paleo-Pacific plates under Eurasian continent.

Seven zircon fission-track ages and 30 magnetic susceptibilities were measured on welded pyroclastic rocks from the Bogopol and Sijanov Groups of the Cretaceous to Paleogene volcanic rocks in the southeastern part of the eastern Sikhote Alin volcano-plutonic belt, Far East Russia. The fission-track ages range from 42.7 Ma to 64.0 Ma which indicate that both the groups are of Early Paleogene time. Two thirds of the samples from the Bogopol Group have high magnetic susceptibility values, more than 3 × 10 -3 SI unit, which imply that they are of the magnetite-series, whereas the samples from the Sijanov Group show 3 × 10 -3 to 8 × 10 -5 SI unit which suggest this group of probably the ilmenite-series.The Paleogene age and high magnetic susceptibility of the Bogopol Group are quite similar to the Paleogene igneous rocks of the San'in belt, Southwest Japan. This suggests, taking accounts of the opening of the Japan Sea, that the eastern Sikhote Alin volcano-plutonic belt continued to the San'in Belt, and that the Paleogene igneous rocks along the Japan Sea coast of Northeast Japan were situated along the volcanic front of the eastern Sikhote Alin volcano-plutonic belt.

Paleo-Pacific subduction-accretion: Evidence from Geochemical and U-Pb zircon dating of the Nadanhada accretionary complex, NE China

et al. 2014

The Nadanhada Terrane, located along the eastern margin of Eurasia, contains a typical accretionary complex related to paleo-Pacific plate subduction-accretion. The Yuejinshan Complex is the first stage accretion complex that consists of meta-clastic rocks and metamafic-ultramafic rocks, whereas the Raohe Complex forms the main parts of the terrane and consists of limestone, bedded chert, and mafic-ultramafic rocks embedded as olistolith blocks in a weakly sheared matrix of clastic meta-sedimentary rocks. Geochemical data indicate that the Yuejinshan metabasalts have normal mid-ocean ridge basalt (N-MORB) affinity, whereas the Raohe basaltic pillow lavas have an affinity to ocean island basalts (OIB). Sensitive high-resolution ion microprobe (SHRIMP) U-Pb zircon analyses of gabbro in the Raohe Complex yield a weighted mean 206 Pb/ 238 U zircon age of 216 ± 5 Ma, whereas two samples of granite intruded into the complex yield weighted mean 206 Pb/ 238 U zircon ages of 128 ± 2 and 129 ± 2 Ma. Laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon analyses of basaltic pillow lava in the Raohe Complex define a weighted mean age of 167 ± 1 Ma. Two sandstone samples in the Raohe Complex record younger concordant zircon weighted mean ages of 167 ± 17 and 137 ± 3 Ma. These new data support the view that accretion of the Raohe Complex was between 170 and 137 Ma, and that final emplacement of the Raohe Complex took place at 137-130 Ma. The accretion of the Yuejinshan Complex probably occurred between the 210 and 180 Ma, suggesting that paleo-Pacific plate subduction was initiated in the Late Triassic to Early Jurassic.
