英文摘要During late Palaeozoic time, extensive magmatism and associated ore deposits were developed in the eastern Tianshan orogenic belt (ETOB), Northwest China, which is part of the Central Asian Orogenic Belt. To understand the petrogenesis of the intrusions in this area, we performed in situ zircon UPb and Hf isotopic analyses on the TuwuYandong (TWYD) stocks and the Xianshan, Hulu, Luodong, and Poshi batholiths. Two major suites of intrusive rocks have been recognized in the ETOB: (1) 338339 Ma plagiogranite porphyries and 265300 Ma ultramafic and mafic rocks, of which the former are associated with 323 Ma porphyry CuMo deposits and have enriched radiogenic Hf isotopic compositions (E-Hf(t) = +11.5 to +15.6), which were derived from a depleted mantle source, whereas the latter are associated with 265300 Ma magmatic NiCu deposits and have variable Hf isotopic compositions (E-Hf(t) = 10.3 to +14.3), indicating an origin via the hybridization of depleted mantle magma and variable amounts of ancient lower-crustal components. The proposed magma sources, combined with the geochemical differences between these two suites of intrusive rocks, indicate that in the lower to middle Carboniferous, a N-dipping subduction zone beneath the Dananhu arc triggered the emplacement of granitic porphyries in the Tousuquan and Dananhu island arc belt in the east Tianshan, leading to the formation of the TW and YD porphyry CuMo deposits. In the Upper Carboniferous to Lower Permian, large maficultramafic complexes were emplaced during the closure of the ancient Tianshan Ocean, resulting in the formation of several magmatic CuNi sulphide deposits.
