“…(Table S1 [see footnote 1]). Microfossils, isotope stratigraphy, and magnetostratigraphy have been used to differentiate between these formations (e.g., Fang et al, 2008;Chang et al, 2008;Pang et al, 2004;Wang et al, 2007;Rieser et al, 2005Rieser et al, , 2009). To date, there are few studies of lithofacies or lateral correlation of these strata, making fi eld identifi cation and/or interpretation of sedimentary environments problematic .…”

“…1; Halimov and Fezer, 1989;Goudie, 2007;Rubin and Hesp, 2009;Kapp et al, 2011). Since at least the Eocene, however, most of the Qaidam Basin has continuously accumulated sediments, and late Paleozoic and Mesozoic sediments were locally deposited prior to the Cenozoic (e.g., Wang and Coward, 1990;Xia et al, 2001;Rieser et al, 2005;Zhuang et al, 2011b). Cenozoic strata are locally >5000 m thick and span from the early Eocene to present (Table S1 in GSA Data Repository 1 ).…”

“…2.6 Ma), the fi rst appearance of gypsiferous shale within the strata provides unequivocal evidence for the evaporite-rich Quaternary Qigequan strata at this location, and it is the basis for our formation boundary. This change from lacustrine to evaporite strata is widespread throughout the Qaidam Basin (Song and Wang, 1993;Rieser et al, 2005;Zhu et al, 2006;Fang et al, 2007;Wang et al, 2012) and implies that the lithofacies change was not a local event but rather a basinwide event due to an overall increase in aridity between 3.1 Ma and 2.6 Ma in the region.…”

“…The Qaidam Basin in central Inner Asia (north of the Tibetan Plateau) provides a key location to explore climate changes, where the effects of the global temperature, Tibetan Plateau uplift and development of the Asian monsoon are preserved due to the basin's ideal location and super-thick Cenozoic sediments (e.g., Rieser et al, 2005;Fang et al, 2007;Wang et al, 2007;Lu and Xiong, 2009;Miao et al, 2011Miao et al, , 2012Wu et al, 2011;Cai et al, 2012;Chang et al, 2012) (Fig. 1a).…”

Cenozoic climate changes in inner Asia provide a basis for understanding linkages between global cooling, the Tibetan Plateau uplift, and possibly the development of the East Asian monsoon. Based on a compilation of palynological results from the western Qaidam Basin, this study reconstructed a 15-million-year (Ma) record of changing vegetation and paleoclimates spanning the middle Miocene to present (comprising two series: ~ 18–5 Ma and ~ 3.1–0 Ma, respectively). The thermophilic percentages were highest between 18 and 14 Ma, and decreased after 14 Ma, closely corresponding to the Middle Miocene Climatic Optimum (MMCO) between 18 and 14 Ma and the following global climatic cooling between 14 and 5 Ma. At the same time, decreases in the xerophytic and coniferous taxa percentages, and the increasing logarithmic ratio of non-arboreal pollen to arboreal pollen (ln (NAP/AP)), reveal the continuous aridification across both the basin and surrounding mountains. Between ~ 3.1 and 0 Ma, the percentages of the thermophilic, xerophytic and coniferous pollen as well as the ln (NAP/AP) imply further cooling and drying in this region since 3.1 Ma. We argue that these vegetation and climate patterns during the late Cenozoic western Qaidam Basin are primarily a result of the global cooling, with the Tibetan Plateau uplift and East Asian summer monsoon having contributions of lesser importance

Most existing tectonic models suggest that the deformation and uplift of the northern Tibetan Plateau is the latest crustal response to the collision of the India Plate and Eurasian Plate. The tectonic evolution of Altyn Tagh Mountain (hereafter called simply the “Altyn Tagh”), on the northern margin of the Tibetan Plateau, has attracted considerable scientific attention. In this study, we use fission track age dates of detrital zircons from the northwestern Qaidam basin together with sedimentary observations to understand more fully the Cenozoic tectonic uplift of the Altyn Tagh. Detrital zircons from five borehole samples distributed in different folds in the northwestern Qaidam basin yielded ages mainly ranging from 88.5 to 49.2 Ma, older than their sedimentary deposition ages (43.8–22 Ma). The binomial distribution in grain age fitted peaks was generally dominated by one young peak, P1, which varied from 73.6 to 47.2 Ma. A thinning of the Cenozoic Lulehe Formation (53.5–43.8 Ma) stretched from the inner Qaidam basin to the slopes of the Altyn Tagh in the seismic sections of the northwestern Qaidam basin. Based on magnetostratigraphic dating, there was a hiatus in sedimentation in the Qaidam basin between 65 Ma and 54 Ma; this was confirmed by seismic profiles and borehole data, which show an unconformity between the Mesozoic Quanyagou Formation and the Lulehe Formation. Combined with an analysis of provenance, the detrital zircon young peak age and the sedimentary record revealed that the most significant regional uplift of the Altyn Tagh occurred during the Paleogene‐Early Eocene, almost coinciding with the collision of the Indian and Eurasian plates between 65 Ma and 44 Ma.
