Two Stratigraphic Concerns on the Central and Northern Tianshan Tectonic Complex, Northwest China
详细信息   
摘要

Two tectonostratigraphic concerns on the Late Paleozoic Tianshan tectonic complex were addressed in this study: 1) the stratigraphic succession of the Bayingou ophilite mélange; and 2) the timing of tectonic accretion of the Siberian craton in the Aiweiergou area by integrating the relevant data of stratigraphy, palaeontology, tectonopaleogeography and tectonopaleobiogeography.  The authors considered that this unconformity indicates the closure of the Tianshan Ocean and final tectonic accretion might have taken place between the latest Permian and Triassic. The authors infer that the closure of the South Tianshan Ocean and tectonic accretion of the Tianshan blocks might have taken place during Late Carboniferous to Early Permian times.
