Geological features and Tectonic significance of melange zone in West Kunlun Taxkorgan

Taxkorgan West Kunlun tectonic melange belt by the composition of the Paleoproterozoic basement rock-chip sector, the mainland Sinian plate rift basalt rock film, Ordovician-Silurian flysch rock film, Carboniferous-Permian volcanic arc rock-chip and high-pressure metamorphic rocks. According to the high-pressure metamorphic, the remnants of oceanic basin and the formation of magmatic arc of time to determine a comprehensive, mixed with melange belt formation in early Paleozoic. The melange belt Kangxiwar for the establishment of the nature of the fault zone and in the West Kunlun tectonic evolution of the research is of great significance, which indicates that further discoveries in the West Kunlun region in early Paleozoic there have been plate subduction and collision course , and hinted that the mazar - Kangxiwar fault may represent the original Tethys - the ancient Tethys subduction and final closure of the line.
