“…Thickness intervals 0-756.6 m, 805.6-908.6 m, 2341-3108.6 m and 3719.6-3824.8 m are poorly constrained. In particular, the chronologic constraint for thickness interval 0-756.6 m is referred to Wang et al (2014) with less confidence, and therefore the SAR in the interval is shown in dashed line. as noted above, provide solid evidence for lithostratigraphic correction of our described section to other section with detailed biostratigraphic constraint.…”

“…These published biostratigraphic results provide approximate dates for the formations. As summarized by Wang et al (2014), traditional biostratigraphic findings, accompanied by mineral and geochemical evidence, suggest that the Aertashi Formation was deposited during early Paleocene (roughly 65-62 Ma) (Guo, 1994;Guo et al, 2000;Hao et al, 2001;Jia et al, 2004;Tang et al, 1989;Wang et al, 2014;Yong et al, 1989). This correlation is supported by the widespread thick gypsum and dolomite beds, providing a distinctive mark for the correlation.…”

“…This correlation is supported by the widespread thick gypsum and dolomite beds, providing a distinctive mark for the correlation. In light of the Bashibulake Formation, detailed biostratigraphic analyses suggest that the deposition of the formation ended at approximately 34 Ma (see Wang et al, 2014 andBosboom et al, 2014 for details). All these discussions suggest that this lower part of the measured section spans age interval of ca.…”

“…S5), similarly reported in northern Pamir (33). Cenozoic sequences in the Pamir-Tianshan convergence zone, changing from an arid continental plain to an intermountain basin by ∼5 Ma, support surface uplift of the west margin of the Tarim Basin (34). Occurrence of detrital apatite fission track ages from West Kunlun Ranges (35) also peaked at ∼4.5 Ma (Fig.…”

The Tibetan Plateau uplift and Cenozoic global cooling are thought to induce enhanced aridification in the Asian interior. Although the onset of Asian desertification is proposed to have started in the earliest Miocene, prevailing desert environment in the Tarim Basin, currently providing much of the Asian eolian dust sources, is only a geologically recent phenomenon. Here we report episodic occurrences of lacustrine environments during the Late Miocene and investigate how the episodic lakes vanished in the basin. Our oxygen isotopic (δ 18 O) record demonstrates that before the prevailing desert environment, episodic changes frequently alternating between lacustrine and fluvial-eolian environments can be linked to orbital variations. Wetter lacustrine phases generally corresponded to periods of high eccentricity and possibly high obliquity, and vice versa, suggesting a temperature control on the regional moisture level on orbital timescales. Boron isotopic (δ 11 B) and δ 18O records, together with other geochemical indicators, consistently show that the episodic lakes finally dried up at ∼4.9 million years ago (Ma), permanently and irreversibly. Although the episodic occurrences of lakes appear to be linked to orbitally induced global climatic changes, the plateau (Tibetan, Pamir, and Tianshan) uplift was primarily responsible for the final vanishing of the episodic lakes in the Tarim Basin, occurring at a relatively warm, stable climate period.Tarim Basin | Late Miocene | aridification | tectonic uplift | Milankovitch

Provenance change of sediment input in the northeastern foreland of Pamir related to collision of the Indian Plate with the Kohistan-Ladakh arc at around 47 Ma

The Pamir plateau forms a prominent tectonic salient that marks the western end of the Himalayan orogen containing several terranes that were accreted to Eurasia from the Late Paleozoic to Cenozoic. A detailed knowledge of the tectonic evolution of the Pamir salient during the Cenozoic is important for our understanding of the intracontinental deformation in the western Himalaya. Although the tectonic evolution of the Pamir salient has long been studied, the timing of collision between the Indian Plate and the Kohistan-Ladakh arc is still a matter of debate. We present new U-Pb ages and Hf isotopes of detrital zircons, magnetic fabrics, and stable isotopes from the foreland basin on the northeastern margin of the Pamir that indicate a change in sediment provenance started at about 47 Ma. Sediments in the southwest Tarim Basin were partially derived from the uplifted and eroded Karakoram and Kohistan terranes created by the collision between the Indian Plate and the Kohistan-Ladakh arc at circa 47 Ma, as a result of northward thrusting and propagation of the Indian Plate under Eurasia.
