The resulting age model serves as a robust framework for paleoclimate reconstruction of Neogene climate dynamics in Central Asia. doi: 10.1002/dep2.34 Cross Ref Full Text | Google Scholar Vollmer, T., Werner, R., Weber, M., Tougiannidis, N., Röhling, H.-G., and Hambach, U. Orbital control on Upper Triassic Playa cycles of the Steinmergel-Keuper (Norian): a new concept for ancient playa cycles. Central Asia's climate dynamics during the Cenozoic, with a general trend of aridification (Guo et al., 2002; Tang et al., 2011; Caves et al., 2015), was mainly driven by global cooling and uplift of the Tibetan plateau (Zhisheng et al., 2001; Lu et al., 2010; Miao et al., 2012). The extent of the Paratethys, together with its advance and retreat largely influenced the atmospheric moisture supply in Central Asia (Fluteau et al., 1999; Bosboom et al., 2011).

Climatically forced moisture supply, sediment flux and pedogenesis in Miocene mudflat deposits of south-east Kazakhstan, Central Asia. To investigate these influencing factors, we study a well-exposed paleoclimatic archive, the Neogene sedimentary succession in the Aktau Mountains (SE Kazakhstan).
The Bastau Fm, with its depositional variability and magneto-mineralogical alteration effects, is an example of a complex continental setting. doi: 10.1111/j.1365-246X.1984.tb01909.x Cross Ref Full Text | Google Scholar Tauxe, L., Kent, D.
The Neogene succession of the Aktau Mountains in the Ili Basin, southeast Kazakhstan, is a terrestrial archive well suited for researching the role of Central Asia in Miocene climate evolution.
We present an integrated approach for dating the well-exposed Bastau Formation, based on magnetostratigraphy and constraints from cyclostratigraphy and biostratigraphy. doi: 10.1007/s11200-011-9018-4 Cross Ref Full Text | Google Scholar Zhang, W.
Stepwise demagnetization yielded characteristic remanence directions that are consistent with those expected for the Miocene in Central Asia.
The reddish-colored alluvial floodplain deposits and gray lacustrine deposits show partly complex magnetic behavior with magnetite and hematite as the main magnetic carriers, with variable demagnetization behavior and non-dipolar normal and reverse polarity directions.
Because of the possible influencing factors mentioned above, it is essential to verify the reliability of each red bed record. doi: 10.1016/0012-821X(80)90044-8 Cross Ref Full Text | Google Scholar Taylor, S.
