“…They, thus, are not considered as provenance sources of the Permian sedimentary basins along the Xar Moron River. However, e.g., Zhou et al [] and Han et al [] proposed that the Erguna, Xing'an, Jiamusi‐Khanka, and Songliao blocks in northeast China have Pan‐African basement and represent fragments that rifted from northern Gondwana, and may have influenced sedimentary systems in the region during Late Paleozoic.…”

“…The overall detrital zircon U‐Pb age distribution of the study area, thus, resembles that of a convergent tectonic setting as recently characterized by Cawood et al [], thus representing a basin environment within or near an active arc system. This is supported by arc‐related volcanic rocks along the Xar Moron River, which are characterized by calc‐alkaline compositions [ Li , ; Zhang et al , ; D. P. Li et al ., 2011; Y. L. Li et al ., 2011a; Han et al , ]. In this study, we show that the Permian sedimentary and volcanic rock suites along the Xar Moron River are geochemically related (Figure ).…”

Final closure of the Paleo‐Asian Ocean along the Solonker Suture Zone: Constraints from geochronological and geochemical data of Permian volcanic and sedimentary rocks

et al. 2014

There is a broad consensus that the Solonker Suture Zone marks the final closure of the Paleo-Asian Ocean, which led to the formation of the eastern segment of the Central Asian Orogenic Belt. However, when and how the final closure occurred still remains controversial. To address this issue, provenance analysis of Permian sedimentary rocks of arc basins along the Xar Moron River was carried out. Geochemical analysis revealed a close relationship between the sedimentary and volcanic rock suite in the study region suggesting short transport distances and a complex convergent arc setting. Detrital zircon U-Pb analysis identified two major age provenances: (1) the Precambrian basement of the North China Craton (~2497 Ma and~1844 Ma) and (2) the Paleozoic Southern Accretionary Orogen along the northern margin of North China (~436 Ma and 269 Ma). The present locations of identified age provenances indicate southward subduction beneath the northern margin of North China. A comparison of the youngest age population in the sedimentary rocks with U-Pb ages obtained for subduction-related volcanic rocks implies that the Solonker Suture Zone formed from the Late Permian to Early Triassic. The results of our study advocate a complex Permian arc system which was probably similar to present-day Southeast Asia.

“…For instance, Han et al . () compared the zircon U–Pb ages and Hf isotopic compositions of detrital zircons in the Permian sandstones collected from the Da Xing'an Mountains (an NNE‐trending Mesozoic orogen north of Solonker suture zone). Their results showed that the zircons with U–Pb ages of ~ 1.8 Ga and ~ 2.5 Ga, which are interpreted as North China Craton affinity, were rarely discovered in Middle Permian Zhesi Formation.…”

Permian back‐arc extension in central Inner Mongolia, NE China: Elemental and Sr–Nd–Pb–Hf–O isotopic constraints from the Linxi high‐MgO diabase dikes

Early Permian (272 ± 2 Ma) diabase dikes from the Linxi area in central Inner Mongolia of NE China have high .2 -6.0 ‰ with an average of 5.7 ‰) than normal mantle. The combined geochemical data indicate their derivation from a depleted mantle metasomatized by recycled crustal component. Elemental and isotopic modeling results suggest that the primary magma was produced through 5 % to 10 % melting of a depleted mantle, which contained approximately 1 % sediment fluid released from the subducted paleo-Asian Ocean. Considering the widespread distribution of contemporaneous mafic rocks across the central Inner Mongolia, which show REE patterns from E-MORBs to normal MORBs, we propose a petrogenetic link between the Early Permian mafic magmatism and a back-arc extension in response to northward subduction of the paleo-Asian Ocean. The Permian mafic magmatism and the new age constraints from the metamorphic and sedimentary records in this area tend to indicate the ultimate closure of the paleo-Asian Ocean by the end of Paleozoic.

Detrital zircon U-Pb dating of the Xingfuzhilu Formation in southern Inner Mongolia yields a maximum depositional age of around 220 Ma. The predominantly Permian and Triassic zircons are characterized by oscillatory zoning and euhedral shapes, with mostly positive zircon ε Hf (t) values (+2.0 to +16.4), indicating that they were derived from a proximal magmatic source. Early-Middle Paleozoic zircons have variable zircon ε Hf (t) values from À6.2 to +11.2 and are characterized by weak oscillatory zoning and subhedral-subrounded shapes, suggesting that the sources are a proximal magmatic arc, possibly mixed with components of the Ondor Sum magmatic arc and the magmatic arc at the northern margin of the North China Craton. The remnants of Precambrian blocks in the southeastern Central Asian Orogenic Belt (CAOB), and the North China Craton may also have been a minor source region for the Xingfuzhilu succession. These results, combined with regional data, indicate that a closing remnant ocean basin or narrow seaway possibly existed in the Middle Permian (Guadalupian) immediately prior to final collision of the CAOB and closure of the Paleo-Asian Ocean. Subsequent collision resulted in the crustal uplift and thickening along the Solonker suture zone, accompanied by possible slab break-off and lithospheric delamination during the Latest Permian to Middle Triassic. The resultant orogen in the Late Triassic underwent exhumation and denudation of rocks in response to the postorogenic collapse and regional extension. Vertical crustal growth in the Triassic is documented by detrital zircons from the Xingfuzhilu Formation and appears to have been widespread across entire eastern CAOB.
