英文摘要	The Tarim Basin, located in the rain shadow of the Tibetan Plateau and other central Asian active orogens, is one of the most arid areas in the mid-latitude of the Northern Hemisphere. Its aridification history is important for understanding climate changes in the context of global cooling and regional tectonics. In this study, we present an environmental magnetism study of the early Miocene-early Pliocene (similar to 20-4 Ma) terrestrial sediments in the Southern Tian Shan foreland. Magnetic parameters representing the relative/absolute concentrations of hematite in the sediments, together with color parameters, are used to reconstruct the Neogene climate evolution of the Tarim Basin. Our results reveal that the Tarim Basin was dominated by relative warm and wet climate between similar to 17 Ma and similar to 14 Ma, corresponding to the Mid-Miocene Climatic Optimum (MMCO), followed by three step-wise cooling/drying events at similar to 14 Ma, 7 Ma and similar to 5.3 Ma, respectively. The dramatic cooling event at similar to 14 Ma is attributed to the expansion of East Antarctic Ice Sheet. The stepwise aridification at -7 Ma and similar to 5.3 Ma in the Tarim Basin was controlled first-order by global cooling but superimposed by regional tectonics. The late Miocene aridification at similar to 7 Ma is partly due to the reduced moisture transport to the Tarim Basin related to the Mediterranean Salinity. Basin-wide extreme aridification since similar to 5.3 Ma is dominated by the final collision between Pamir and Tian Shan, which blocked the water-vapor brought by the westerlies from the Paratethys Sea to the downwind Tarim Basin.
