“…The CTS was formerly assumed as an independent block that was separated from the Tarim Craton during the Neoproterozoic (Wu et al., 2022a, 2022b). However, recent investigations on xenocrystic zircons from basement rocks and detrital zircons from Neoproterozoic to early Paleozoic sedimentary sequences from both CTS and northern Tarim exhibited comparable age patterns (Han et al., 2015; Ma et al., 2012a, 2012b; X. S. Wang et al., 2017c).…”

While the western part of northern Tarim Craton has long been considered as a Paleozoic passive margin, a pronounced Silurian‐Devonian magmatism developed on eastern part of this margin may indicate different but active margin setting. In this contribution, detailed structural mapping, petro‐structural analysis, and geochronological investigations were conducted in the Korla area, eastern part of northern Tarim Craton. Three main generations of fabrics were recognized. The earliest pervasive fabric is an originally sub‐horizontal metamorphic S1 foliation that is in part associated with migmatization characterized by high temperature/low pressure metamorphic mineral assemblages, interpreted as reflecting crustal extension. S1 foliation was affected by D2 contraction forming regional‐scale F2 upright folds associated with sub‐vertical axial planar foliation S2. D3 is marked by development of NW‐SE oriented dextral fault, asymmetric mega‐folding of S2 and spaced NW‐SE‐striking S3 foliation, likely in response to dextral transpression. Geochronological data indicate that D1 extension occurred from ca. 420 Ma to 410 Ma, D2 contraction started around 410 Ma and lasted till 400 Ma or later, and D3 transpression was ongoing around ∼370 Ma. Integrated with regional data, an updated geodynamic model is proposed by interpreting the Central Tianshan, South Tianshan and NE Tarim Craton as an early Paleozoic supra‐subduction system. We suggest that the Silurian‐Devonian event reflects thermal softening and horizontal stretching of the supra‐subduction crust, resulting in drifting of the Central Tianshan continental arc from the proto Tarim Craton in association with opening of the South Tianshan back‐arc basin in‐between.This article is protected by copyright.

“…835 Ma was followed by syncollisional magmatism in the Aktau-Yili terrane and Chinese Central Tianshan. The subsequent mafic and bimodal contrast magmatism reflects post-collisional extension during 740-610 Ma (Wu et al, 2022).…”

“…In the Alataw and Yili areas of northwestern China, the Neoproterozoic magmatism occurred over a longer time interval from ca. 980 to 800 Ma and was accompanied by forming various granitoids with I-, S-and A-type geochemical characteristics (Xiong et al, 2019;Sun et al al., 2022, Wu et al, 2022. These granites were interpreted as reflecting subduction-collisional tectonics during the early Neoproterozoic, related to the emplacement of syncollisional S-type granites during ca.…”

“…The Neoproterozoic A-type granitoids of the Junggar Alataw and Aktau-Mointy areas of Kazakhstan formed in a short period (928-917 Ma) compared to the age of the primary magmatic realm in NW China. They were likely located some distance from the primary convergence zone related to a collisional belt or continental arc in the models of Xiong et al (2019) and Wu et al (2022), respectively. In the context of Xiong et al's (2019) model, the A-type granitoids of Kazakhstan might reflect intraplate magmatism in areas adjacent to the collisional belt.…”

The combined petrographic, petrological, geochemical and geochronological study of the Neoproterozoic gneisses of the Sarychabyn and Baskan complexes of the Junggar Alataw of South Kazakhstan elucidate the Precambrian tectonic evolution of the Aktau–Yili terrane. It is one of the largest Precambrian crustal blocks in the western Central Asian Orogenic Belts. The U–Pb single‐grain zircon ages indicate that granite‐gneisses formed from the same source and crystallised in the early Neoproterozoic ca 930–920 Ma. The chemical composition of gneisses corresponds to A2‐type granites. The whole‐rock Nd isotopic characteristics (ɛNd(T) = −1.0 to −4.9 and TNd(DM‐2st) = 1.7 to 1.9 Ga) indicate the involvement of Paleoproterozoic crustal rocks in magma generation. Early Neoproterozoic ca 930–920 Ma A‐type granitoids in the Aktau–Yili terrane of South and Central Kazakhstan might reflect within‐plate magmatism adjacent to the collisional belt or a local extension setting in back‐arc areas of the continental arc.
