“…These features, together with the results (all fall in the continental arc areas) in multiple tectonic discrimination diagrams, indicate that these plutonic rocks were generated from an immature continental arc setting (Sun et al, ). Bi et al () also demonstrated that the Early Permian volcanic rocks in the Baoqing area were produced from island arc or active continental margin settings. All together, it appears that the active continental margin in the Early Permian was significant and expanded for a relatively large spatial and temporal scale in the region.…”

“…Our new LA‐ICP‐MS U–Pb zircon dating results of the andesites within the Erlongshan Formation suggest that these andesites at the eastern edge of the Jiamusi Block were formed at ~280 Ma, indicating an age of Early Permian rather than late Permian. In addition, adjacent areas also have a large number of igneous rocks with Early Permian ages (Figure ), such as the Liulian hornblende gabbro (zircon age of 278 Ma; Yu et al, ), the Tiexi diorite (zircon age of 296 Ma; Yang et al, ), the Dongfanghong gabbro (zircon ages of 275 Ma; Sun et al, ), the basalt‐andesite in the Hajiatun Formation (zircon age of 275 Ma; Bi et al, ), the andesite in the Erlongshan Formation (zircon age of 293 Ma; Meng et al, ), the gabbro‐diorite in the Longtouqiao Formation (zircon age of 275 Ma; Bi et al, ), and the Rizao gabbro (zircon ages from 282 to 290 Ma; Bi et al, ). These igneous rocks with almost identical ages indicate that large‐scale volcanic events occurred in the study region and adjacent areas in the Early Permian.…”

“…Both Guangqing and Zhenzishan formations are mainly composed of terrestrial clastic rocks, including minor amounts of coal seams (Heilongjiang Bureau of Geology and Mineral Resources (HBGMR), ). Three zircon U–Pb ages of 263 ± 5 Ma, 267 ± 5 Ma, and 269 ± 3 Ma were reported for a dacite, a rhyolite, and a rhyolitic crystal tuff in the Zhenzishan Formation (Bi et al, ; Meng et al, ). Late Carboniferous to Early Permian plant fossils ages (Huang, ; Yuan, ), and detrital zircon U–Pb ages of 315 ± 1 Ma (Li et al, ) were also reported for the Zhenzishan Formation.…”

The Jiamusi Block is an important tectonic unit in the Chinese segment of the CAOB. Its eastern margin became an active continental margin in the period of Late Carboniferous. However, the tectonic affinity of this section has not been resolved yet. The Early Permian andesites within the Erlongshan Formation in the eastern Jiamusi Block provide a critical record for the active continental margin setting. Precise LA‐ICP‐MS U–Pb zircon dating on four andesite samples gave ages of 280 ± 3 Ma, 282 ± 3 Ma, 286 ± 4, and 284 ± 2 Ma, respectively, defining an Early Permian age for the crystallization of the andesites. The andesites have medium‐K and calc‐alkaline compositions, with variable SiO2 (54.70–57.46 wt%), TiO2 (0.87–1.12 wt%), TFe2O3 (6.52–8.13 wt%), MgO (2.62–3.33 wt%), Al2O3 (15.96–17.83 wt%), Na2O (3.28–4.10 wt%), and K2O (1.16–1.95 wt%) contents. They are relatively enriched in LREEs ((La/Yb)N = 5.0–7.1) and LILEs (e.g., Ba, Th, Sr, and U), deleted in HREEs and HFSEs (e.g., Nb, Ta, Zr, and Y) and have weak or no Eu anomalies (Eu/Eu* = 0.87–1.02). These geochemical features indicate that the andesites within the Erlongshan Formation originated from an active continental margin setting, and their magma source was produced by partial melting of a mantle material that had been metasomatized by subduction‐related melts and subsequently underwent the removal of mafic minerals and accumulation of plagioclase. Integrated with previous studies on the igneous and sedimentary rocks, we thus propose that the Jiamusi Block was in an active continental margin setting in the period of the Late Carboniferous to Early Permian (310–280 Ma), and it is more likely related to the subduction of the Mongol‐Okhotsk Ocean.

“…Early Permian volcanic rocks have been reported by Meng et al (), composed mainly of basalt, rhyolite (291 ± 2 Ma), basaltic andesite (293 ± 2 Ma), and minor dacite (~288 Ma), with their geochemical features implying that a continental arc exist in the eastern margin of the Jiamusi Block. In addition, early‐middle Permian (290–267 Ma) bimodal volcanic rocks in the Baoqing area are characterized by enrichment in large‐ion lithophile elements (LILE) and light rare earth elements (LREE), with depletion in high‐field‐strength elements (HFSE), also indicating that the magmas formed in an island arc or active continental margin setting (Bi et al, ). Therefore, we propose that the Jiamusi Block separated from the Songliao Block as a result of back‐arc extension during the Permian.…”

LA‐ICPMS zircon U–Pb dating of the Heilongjiang Complex in the Luobei area: New constraints for the late Palaeozoic‐Mesozoic tectonic evolution of Jiamusi Block, NE China

et al. 2019

The Heilongjiang Complex is a sequence of high‐pressure (HP) metamorphic rocks that are distributed along the N‐S suture zone between the Jiamusi and Songliao blocks in NE China. In this study, we investigated samples from Luobei in order to understand the geochronological and tectonic framework of the Heilongjiang Complex. The Heilongjiang Complex consists of two‐mica schist, muscovite‐albite schist, quartz schist, plagioclase gneiss, granitic gneiss, serpentinite, blueschist, greenschist, amphibolite, and marble. LA‐ICP‐MS dating of all samples shows a range of protolith ages from 435 to 210 Ma. These data, together with a 492 ± 6 Ma age from a granite gneiss sample in the Yilan area, indicate that the protoliths of the Heilongjiang Complex were formed over a protracted time span from ~490 to ~210 Ma. In addition, five zircon grains in two samples contain metamorphic rims that yield ages of 197 ± 2 Ma. These results, when combined with field evidence that the Heilongjiang Complex is overlain by Middle Jurassic strata, indicate it was metamorphosed between ~210 and 197 Ma and not in the Cretaceous as previously considered. This line of evidence, plus the occurrence of late Palaeozoic arc‐affinity volcanic rocks in the eastern margin of the Jiamusi Block and syn‐collisional Mesozoic volcanic rocks in the Zhangguangcai and Lesser Xing'an ranges, suggests the Heilongjiang Complex was a result of Panthalassa subduction during the late Palaeozoic and Paleo‐Pacific subduction during the Mesozoic.

“…The granitoids in the JM were emplaced in two main stages during the early Palaeozoic (Bi, Ge, Yang, et al, ; Wilde et al, ; ; Yang et al, ) and Permian (Bi et al, ; Bi, Ge, Zhang, et al, ; Huang, Ren, et al, ; Wu, Wilde, & Sun, ; Yang, Ge, Zhao, Yu, & Zhang, ; Zhang et al, ). The late Palaeozoic volcanosedimentary rocks occur mainly along the eastern part of the massif and comprise the Devonian Heitai, Laotudingzi, and Qilikashan formations; the Carboniferous Beixing and Zhenzishan formations; and the Permian Erlongshan Formation (Bi et al, ; ; HBGMR, ; Meng et al, ). The JM also contains a late Palaeozoic accretionary complex, the Yuejinshan Complex (Bi et al, ; Figure b), which contains strongly deformed metasedimentary rocks and greenschist‐facies metamorphosed mafic to ultramafic rocks (Bi et al, ; Yang, Qiu, Sun, & Zhang, ), and is intruded by Permian gabbro (Bi et al, ; Sun, Xu, Wilde, Chen, & Yang, ).…”

This paper presents new zircon U–Pb ages and Hf isotope data, and whole‐rock major and trace element geochemical data of Permian igneous rocks from the eastern Songnen Massif (SM) and the western Jiamusi Massif (JM), NE China, to constrain their tectonic evolution. Zircon U–Pb dating indicates that Permian magmatism within the eastern SM can be subdivided into two stages: early Permian (ca. 293 Ma) and middle to late Permian (272–257 Ma). The early Permian igneous rocks comprise a bimodal association of rhyolites, basaltic andesites, and gabbros. The middle to late Permian igneous rocks are dominated by gabbro–diorites, monzodiorites, quartz diorites, monzonites, quartz monzonites, granodiorites, monzogranites, syenogranites, and alkali feldspar granites, along with minor bodies of A‐type quartz trachytes. The Permian felsic magmas originated mainly from partial melting of a relatively juvenile lower crust, whereas the coeval mafic rocks were probably derived from partial melting of a relatively depleted lithospheric mantle that was modified by fossil subduction‐related fluids. The igneous rock associations and their geochemical features, together with data from coeval sedimentary and volcanosedimentary successions, indicate that Permian magmatism within the eastern Songnen and western Jiamusi massifs formed in an extensional environment, similar to a back‐arc setting, related to westward subduction of a Palaeo‐oceanic plate beneath the eastern margin of the Jiamusi Massif. We find no evidence for double‐sided subduction of the Mudanjiang oceanic plate during the Permian.
