中文摘要	由于对地球表层环境和大气环流形式产生了明显变化,青藏高原在新生代持续快速的隆升过程,就成为重要而壮观的全球变化事件之一。对该事件的关注与研究,产生了许多重要的科学概念和成果,同时也产生了许多争论。发育在青藏高原东北缘即甘肃省酒泉地区的新生界风成砂岩及其相关沉积,代表了青藏高原新生代隆升过程中造成的环境变化的特殊沉积。它们包括:(1)古近系白杨河组底部的风成砂岩,代表了受到印度夏季季风控制的炎热干旱环境的产物;(2)新近系疏勒河组下部的风成砂岩,表明了继续受到印度夏季季风控制的潮湿气候背景的沉积;(3)第四系玉门组冰水沉积中的风成砂岩透镜体,表现为冬季季风(或盛行西风)形成的寒冷气候下的风成砂岩。因此,研究区域的新生界风成砂岩,成为窥视青藏高原新生代隆升的沉积学响应,为研究青藏高原的新生代隆升过程提供了重要思考线索。
英文摘要	Since it led to the obvious change of both the surface environment of the Earth and the pattern of the atmosphere circulation,the rapid persisting uplift of the Qinghai-Tibet Plateau during the Cenozoic is an important and conspicuous event of the global change.Lots of important concepts and ideas were resulted from studies on this important event,and many controversies were also caused from these studies.Aeolian sandstones and their relative deposits of the Cenozoic in Jiuquan area represent particular deposits formed by the environmental change that was controlled by the persisting uplift of the Qinghai-Tibet Plateau during the Cenozoic.These aeolian sandstones are:(1)aeolian sandstones in the bottom part of the Paleogene Baiyanghe Formation,which delegated the product formed in arid and torrid environment controlled by Indian Summer Monsoon;(2)aeolian sandstones in the lower part of the Neogene Shulehe Formation,which represented the deposit generated in the humid environment that was also controlled by Indian Summer Monsoon;(3)lens of aeolian sandstones within the Quaternary Yumen Formation,which were resulted from the cold environment caused by the Winter Monsoon(or the Westerlies).Therefore,aeolian sandstones of the Cenozoic in the study areas became the importantly sedimentological response to peek the uplift of the Qinghai-Tibet Plateau during the Cenozoic,and provided an important thinking clue for further research on the uplift process of the Qinghai-Tibet Plateau during the Cenozoic.
