| 摘 要： | 近两年对准噶尔盆地北缘第三纪地层进行了进一步调查和研究，在索索泉组和哈拉玛盖组内发现了新的化石层位。对新发现的哺乳动物的研究表明在勒布勒津地区索索泉组顶部的沉积物时代为中中新世，下部的沉积物时代不晚于晚渐新世，中新世与渐新世地层的界线应在索索泉组内寻找。新发现的动物群分子Cricetodonsp．nov．和Tachyoryctoidessp．nov.指示哈拉玛盖动物群的时代应重新考虑，有可能早于丁家二沟动物群。

| Abstract: | During two fleld seasons in 1995-96, we have measured three geological sections respectively at Duolebulejin, Chibaerwoyi, and Tieershabahe along the south and northbanks of the Ulungur River, Xinjiang Province, Northwest China. We have carefullytraced the exposures of these strata to accomplish comprehensive lithological correlations. For biostratigraphic study, we have collected numerous vertebrate fossils,mainly mammal remains, from several well-defined levels of these sediments. These fossils are listed below: |
