Mesozoic–Cenozoic multistage tectonic evolution of the Pamir: Detrital fission‐track constraints from the Tajik Basin

Abstract Knowledge of the tectonic history Pamir contributes to our understanding both evolution collisional orogenic belts as well factors controlling Central Asian aridification. It is, however, not easy decipher Mesozoic–Cenozoic tectonics due extensive Neogene deformation in an orogen that remains largely understudied. This study reports detrital apatite and zircon fission‐track (FT) ages from eastern Tajik Basin sedimentary rocks modern river sands. These FT data, supported by vitrinite reflectance U–Pb double dating, suggest majority are unreset record exhumation stages Pamir, which has served source terrane since Cretaceous. Furthermore, we combine new data with a compilation published sands, explore Pamir. Deconvolved Peak Ages document two major Mesozoic events associated Late Triassic–Early Jurassic Cimmerian orogeny reflects accretion terranes, Early–early Cretaceous northward subduction Neo‐Tethys Ocean beneath The compiled also show significant Eocene–Neogene ongoing formation peaks at ca. 36, 25, 14 7 Ma.
