Abstract Accretionary orogens generally involve trench advance and retreat, recognition of which is critical to understand the thermal evolution geodynamics lithosphere. A systematic study has been conducted on Silurian Carboniferous volcanic rocks from Dananhu‐Harlik arc in Chinese eastern Tianshan. Three distinct episodes volcanism have recognized: Late normal andesite, high Sr/Y andesite sanukitoid, Devonian bimodal high‐alumina basalt dacite, Early basalt. These magmatism experienced...
Abstract Identification of subduction to post-collisional tectonic transitions is critical the study orogenic belts. To characterize such a transition in Tianshan Orogenic Belt, systematic was conducted on late Carboniferous (305–301 Ma) Hongshankou dolerite and Dikan’er basalt Eastern Tianshan. The dolerites have relatively high Ti Nb contents, akin Nb-enriched arc basalts. Based Nb/La ratios, these can be divided into low-Nb/La (0.35–0.40) high-Nb/La (0.67–1.4) groups, which were likely...
Abstract The transition from breakup of Nuna (or Columbia, 2.0–1.6 Ga) to assembly Rodinia (1.0–0.9 is investigated by means U‐Pb and Lu‐Hf data detrital zircons three Neoproterozoic metasedimentary rocks in the Central Tianshan Block (CTB), NW China. These yield six age peaks around 1.0, 1.13, 1.34, 1.4–1.6, 1.75, 2.6 Ga. Few are detected between 2.0 2.5 Paleoproterozoic have Hf isotopic compositions (−22.1 +13.0) similar those coeval magmatic CTB, indicating a proximal provenance. results,...
Lithospheric foundering, through mechanical delamination or convective dripping, has been invoked to elucidate various perplexing geological phenomena, including near-surface deformation, sedimentation, and volcanism. Compared delamination, direct evidence for the existence of modern lithospheric drips challenging acquire because their small-scale transient nature. Here we present an image crustal upper mantle electrical resistivity derived from high-quality, long-period magnetotelluric...
Abstract Origins of early Paleozoic metabasites (granulites and amphibolites) their host metasedimentary rocks in the Dunhuang block, NW China, are addressed by new geochronological geochemical data. The show back-arc basalt–like features, marked high Zr/Nb ratios Zr-Hf troughs, but they can be classified into two groups based on dissimilar protolith ages distinct Nd signatures. Most group I metabasaltic were emplaced before 455 Ma possess Ba/Nb (11.46–224), low (Nb/La)PM (0.10–0.71),...
Decoding the crustal and tectonic evolution of ancient accretionary orogens is not always straightforward. Here, four episodes Paleozoic granitoids have been identified with distinct zircon–Hf isotopic characteristics from Northeastern Tianshan. The first stage in Dananhu–Harlik arc system are characterized by highly positive zircon ε Hf ( t ) values short incubation times a rising event signature, suggesting northward trench advance for Kangguer Ocean. During second stage, Dananhu belts...
