“…This supports the southeasterly swing of the main suture (Fig. 4) and is also in agreement with paleobotanical data from the Xar Moron-Changchun segment that show the suture marks the boundary between Permian Angaran cool temperate flora to the north and Cathaysian tropical flora to the south (Huang, 1983(Huang, , 1991Wang and Liu, 1986;Sun et al, 2013b). The weight of evidence thus suggests that suturing along the Xar Moron-Changchun segment occurred in the late Permian (Wu et al 2007).…”

This study presents zircon U–Pb ages and geochemical and Sr–Nd isotopic data for acid granites from the Uliastai continental margin, which is located in the Ulaan Tolgoi area of the south‐eastern Central Asian Orogenic Belt (CAOB). Although most samples have similar calc‐alkaline (K2O/Na2O = 0.55–1.70, average of 1.35) and peraluminous (A/CNK = 1.02–1.20 and A/NK = 1.09–1.87) characteristics, the granodiorites, monzogranites, and alkali feldspar granites exhibit distinct light rare earth element (LREE)/heavy REE (HREE) anomalies, including negative Nb, P, Ti, Sr, and Ba anomalies and negative εNd(t) values. These characteristics indicate that this complex massif comprises lower Early Carboniferous subduction‐related calc‐alkaline granodiorites (348 ± 1 Ma); an upper Early Carboniferous syn‐collisional segment characterized by S‐type, high‐K, calc‐alkaline, and peraluminous monzonitic granites (334 ± 1 Ma); and Late Carboniferous post‐orogenic extensional A2‐type peraluminous alkali feldspar granites (317 ± 1 Ma). Previous studies performed on coeval volcanic rocks and Early Palaeozoic granites in the same area have demonstrated that the Early Carboniferous granodiorites have the same geochemical characteristics as volcanic arc granites (VAGs), thus indicating that the northward subduction of the Hegenshan Ocean may have continued through the Early Carboniferous. The monzogranite and alkali feldspar granites, in conjunction with the Late Carboniferous lagged arc volcanic rocks observed in this area, suggest a syn‐collisional to post‐collisional setting. The new data presented in this study provide constraints on the timing of the transition from island‐arc magmatism to post‐collisional extension‐related magmatism in this region during the later stage of the Early Carboniferous.

“…Another viewpoint suggests that the Xar Moron–Changchun Suture represents the final closure of the Palaeo‐Asian Ocean between the NCC and Mongolia Terrane, based on a regional synthetical analysis of available geological and palaeontological data, and the difference of the Palaeozoic strata on either side of the Xar Moron River (Li, ; Huang, ; Wang and Liu, ; Li, ; Wu et al ., ; Y. Sun et al , , Y. W. Sun et al , ). Discontinuously outcropping ophiolites, radiolarian cherts, syn‐collisional granites, strongly deformed rocks, island‐arc volcanic rocks along the Xar Moron–Changchun Suture support this viewpoint (Tang et al ., ; Wang and Liu, ; Wang and Fan, ; Sun et al ., ; J. Y. Li et al ., ; Han et al ., ).…”

Geology, geochemistry and tectonic setting of the Indosinian Mo deposits in southern Great Hinggan Range, NE China

The southern Great Hinggan Range in northeast China, mainly bounded by the Kangbao–Chifeng Fault to the south and the Hegenshan–Heihe Suture to the north, is a Palaeozoic subduction‐related accretionary belt added to the northern margin of the North China Craton. The area has been considered as a Yanshanian metallogenic province, with more than 20 Mo deposits being discovered. Recently, six of the Mo deposits were proven to have formed during the Indosinian (Triassic) Orogeny, indicating the significance of the Indosinian mineralization, orogeny and magmatism. In this contribution, we summarize available data of the Indosinian Mo deposits, and show that Triassic Mo mineralization occurred in the time range of 248–232 Ma, coincident with a regional granitic event, and was presented as porphyry and intrusion‐related quartz vein systems. The Indosinian ore‐related granitoids show geochemical features of high‐K calc‐alkaline metaluminous–peraluminous and adakitic rocks, and have been formed by partial melting of thickened lower crust in a post‐subduction tectonic setting. Rhenium contents of molybdenite crystals and sulphur–lead isotopic compositions indicate that the ore‐forming materials originated from continental crust with some mantle components involved.
