| 英文摘要 | Late Palaeozoic evolution of the Chinese Altai-East Junggar orogenic collage is vital for a better understanding of the accretionary evolution in the southern Altaids. This paper reports new geochronological, geochemical, and isotopic data for the magmatic rocks collected from the northern part of the Dulate arc. The similar to 304.6 Ma tonalite samples present typical adakitic features of high Sr (396-714 ppm), low Y (1.42-2.60 ppm), Yb (0.11-0.24 ppm), and high Sr/Y (177.25-440.23) ratios. Combining high Mg# (55.35-57.21) and depleted isotopic composition (epsilon(Hf)(t): +9.89 to +13.37 and epsilon(Nd)(t): +5.36 to +6.06), we suggest that they were derived from the partial melting of a subducted oceanic slab. The similar to 299.4 Ma monzogranite samples have high A/CNK values (1.08 to 1.25), CIPW normative corundum contents (1.28-3.25 wt.%), and positive epsilon(Hf)(t) (+5.14 to +8.63) and epsilon(Nd)(t) (+1.08) values, which are similar to S-type granite that may be generated by the melting of greywackes. The monzogranite (similar to 286.9 Ma) and rhyolitic porphyry (similar to 283.9 Ma) are high-K calc-alkaline and similar to the highly fractionated I-type granites with depleted isotopic features (epsilon(Hf)(t): +11.68 to +14.99 and +0.75 to +7.18, epsilon(Nd)(t): +5.91 and +6.18). The monzogranite and rhyolitic porphyry could have been derived from a depleted mantle source, but the rhyolitic porphyry probably suffered partial assimilation of the overlying crust materials. Combining regional rock associations of mafic-ultramafic complexes, adakitic rocks, high-Mg diorites, and A-type granites with close spatial-temporal relationship, we conclude that a mid-oceanic ridge of the Ob-Zaisan Ocean subducted southward beneath the Dulate arc during the latest Carboniferous to Permian. With the opening of the slab window, the upwelling asthenosphere provided high heat flux and triggered various magmatism in the upper plate. We propose that ridge subduction is one of the most effective mechanisms of continental growth in the southern Altaids. |
