Middle to late Miocene growth of the North Pamir

How and when the Pamir formed remains an open question. This study explores tectonics recorded in a sedimentary section eastern Tajik Basin. A prominent lithofacies change that has been recognised regionally is assigned to middle Miocene (13.5 Ma based on preferred magnetostratigraphic correlation). Closely following this change, detrital zircon U-Pb age spectra mudstone bulk-rock εNd values exhibit sediment source from Central North estimated ca. 12 Ma. At same time, stable oxygen carbon isotopic of carbonate cements show negative positive shifts, respectively. Combined with previous studies both Tarim basins, these results suggest experienced middle–late phase deformation surface uplift. supports models proposing tectonism, climate implying coeval orogenesis deflected Westerly moisture affected Asian environments.
