新疆准噶尔盆地北缘夺勒布勒津台地西侧的索索泉组与上覆哈拉玛盖组为连续堆积地层,在该地测制的地层剖面,完善了索索泉组,并可与铁尔斯哈巴合剖面连接,组成时间跨度为25~13.5Ma的基本上连续的夺勒布勒津-铁尔斯哈巴合综合剖面.索索泉组厚约150m,是以风成沉积为主体的地层.该组堆积始于地磁极性时C6Cr顶,止于C5Cr,地质时间约为24~17Ma,跨越了最晚渐新世至早中新世晚期近7Ma的时间.夺-铁剖面岩性变化明显、含多层哺乳动物化石且古地磁记录较完整,是目前研究中国北方该时段中陆相哺乳动物年代和气候环境变化的理想剖面.剖面也为了解现代亚洲风系和风成沉积的形成过程、亚洲中纬度内陆地区的干旱化过程以及这个过程与全球环境变化、青藏高原隆升、副特提斯海的退缩等因素的关系,提供了新的认识和证据.
The Sosuoquan Formation and the overlying Halamagi Formation in the northern part of the Nurbuluzuzu Platform on the northern margin of the Junggar Basin in Xinjiang are continuously accumulating strata. The stratigraphic profile measured here has perfected the Soxoquan Formation and can be used with Tieer Sjobasha profile, forming a basically continuous Nurbulejin-Karshaba co-profile with a time span of 25-13.5 M. The Sosuoquan Formation is about 150 m thick and is mainly composed of aeolian deposits. This group of sediments began at the top of the geomagnetic polarity C6Cr, ending at C5Cr, with a geological time of about 24-17 Ma, spanning from the latest Oligocene to late Early Miocene for a period of nearly 7 Ma. , Which contains multi-layer mammalian fossils and complete paleomagnetic records, is an ideal profile for studying the age and climate change of terrestrial mammals in the northern part of China in this period. In order to understand the formation process of modern Asian wind systems and aeolian deposits, The arid process in mid-latitude inland Asia and the relationship between this process and global environmental change, the uplift of the Tibetan Plateau and the withdrawal of the Tethys Sea provide new insights and evidence.
