| 英文摘要 | The Altai is an enigmatic, relatively young mountain belt with sharp relief (up to 4,500 m high) that developed thousands of kilometers away from the nearest current plate margins. The Fuyun area, at the interface between the southern margin of the Chinese Altai and the Junggar Basin, represents a key locality for understanding the Meso-Cenozoic deformation and exhumation history of the Altai. The complex structural architecture of the Fuyun area suggests that multiple deformation events affected the area, which ultimately led to the exhumation of the Altai. Furthermore, the area hosts orogenic-type mineralization, suggesting a history of fluid alteration. However, in contrast to the well-constrained Palaeozoic history, the timing of Meso-Cenozoic deformation, metasomatism and exhumation has not been comprehensively studied. This study presents new apatite U-Pb, trace element and fission track data for the Fuyun area and integrates these with previous studies for the Altai to shed more light on the Meso-Cenozoic tectonic history. The apatite U-Pb dates, associated with LREE-depleted trace element profiles, suggest that a phase of Middle-Late Jurassic (similar to 170-160 Ma) metasomatism affected the Keketuohai area, which is potentially linked to the timing of rare-metal mineralization. The apatite fission track results and thermal history models reveal rapid early Late Cretaceous (similar to 100-75 Ma) cooling linked to tectonic exhumation throughout the Chinese Altai, associated with distant plate-margin processes. In addition, samples taken in vicinity to the frontal thrusts of the Altai record evidence for Cenozoic partial resetting of the apatite fission track system. |
