1Central Asian aridification during the late Eocene to early Miocene inferred from preliminary study of shallow marine-eolian sedimentary rocks from northeastern Tajik Basin显示文摘The tempo-spatial development of the Cenozoic Asian aridification across the Eocene-Oligocene and its controlling factors are important scientific topics in Earth Sciences, which are pertinent to regional and global tectonic and climatic events. However, sedimentary rocks preserving the record of aridification during this time from central Asia(ACA) are rare. Here we present a preliminary analysis of sedimentary facies of the lower Paleogene in the northeastern Tajik Basin, which reveals that: the lower part of the studied section is dominated by shallow marine deposits of the Paratethys, the middle part is typical of alternations of eolian dune and fluvial deposits, the upper part is represented by eolian loess-sandy loess(L&SL) like facies, and the top exhibits alternations of fluvial-lacustrine and loess like facies. Based on a chronological framework derived from preliminary magnetostratigraphy, published U-Pb dating of a volcanic ash, and regional litho-stratigraphic correlations, we determine that eolian and L&SL facies accumulated in the northeastern Tajik Basin during the Late Eocene and through most of the Oligocene. These sedimentary units indicate that semi-arid to arid environments of ACA had developed at least since the late Eocene. This initial aridification is closely linked to the westward retreat of the Paratethys that was likely driven by a combination of tectonic activity and sea level changes.WANG Xin Brian KRAATZ Jin MENG Barbara CARRAPA Peter DECELLES Mark CLEMENTZ Sherzod ABDULOV CHEN FaHu 2016Science China Earth Sciences2016,59,6:9
2塔吉克盆地东北缘海相-风成沉积序列与中亚晚始新世-早中新世干旱化的初步研究显示文摘新生代亚洲内陆干旱化的时空演化历史及其驱动机制,是国际古环境研究的热点和重点,然而至今缺少直接来自中国境外干旱区的新生代干旱化记录.对塔吉克盆地东北缘代表性剖面的沉积相分析结果表明,该地区早新生界地层底部以副特提斯海沉积序列为主,中部为厚层风成砂与河流砂交互沉积,上部以风成黄土、砂黄土状堆积为主,顶部为河湖相沉积和风成黄土状堆积交互沉积.根据已发表的火山灰U-Pb年代、初步的古地磁年代框架及区域地层划分证据,风成砂和黄土、砂黄土状堆积物形成于晚始新世和渐新世,表明中亚的干旱环境可能从始新世晚期已经开始,其形成和发展与构造活动驱动的晚始新世副特提斯海退缩密切相关.王鑫 Brian KRAATZ Jin MENG Barbara CARRAPA Peter DECELLES Mark CLEMENTZ Sherzod ABDULOV 陈发虎 2016中国科学:地球科学2016,46,5:5
