| 摘 要： | 根据在新疆于田县普鲁地区新发现的中侏罗世地层及抱粉组合面貌的分析对比，参照其它动物及轮藻化石等，该套地层的时代应为中侏罗世早期，层位与杨叶组相当。结合本区侏罗纪地层层序、岩性及岩相变化、接触关系等，探讨了杨叶期的古地理环境，于田及其周缘地区为杨叶期沉降中心所在，策勒至民丰之间可能是今后找油的有利区段。

| Abstract: | According to the new discovery of the Middle Jurassic in Pulu of Yutian,Xinjiang and the sporo-pollen analysis, as well as the records of other animal and charophyte fossils, the paper regards the strata there as of early Middle Jurassic age, equivalent to the Yangye Formation. Combined with the Jurassic stratigraphic sequences, the changes in lithologic charaters and lithofacies and the contact relation, the paleogeographic environments during the Yangye time are discussed. It is pointed out that Yutian and its neighbourhood may be the depocenter during the Yangye time and the area between Cele and Minfeng may be an area with great potential for the search after petroleum. |
