  1. Advances in the Study on the Chronostratigraphy of the Ediacaran Period in the World and Developments in Future

    国际埃迪卡拉系年代地层学研究进展与发展趋势

  2. It is the first SHRIMP U-Pb zircon age obtained nearly the base of the Sinian ( Ediacaran ) Doushantuo Formation and represents a maximum age of the Doushantuo Formation .

    这一定年结果是目前中国震旦(埃迪卡拉)系陡山沱组底部首次获得的SHRIMP锆石U-Pb年龄。

  3. Dr Zhu also plans to push back before the Ediacaran period .

    朱博士还计划将研究倒推至埃迪卡拉纪以前。

  4. The last and most dramatic rise in oxygen took place towards the end of the Ediacaran .

  6. Barite from the Top Ediacaran Doushantuo Formation in the East Yangtze Gorges Area and Its Geological Implications

    峡东伊迪卡拉纪陡山沱组顶部重晶石特征与地质意义研究

  7. Such places are valuable because in most parts of the world there is a gap , known as an unconformity , between the Ediacaran and the Cambrian .

    由于世界的大部分的此地区都有裂缝,即不整合面,因此埃迪古拉纪和寒武纪之间的这些地方是变化多样的。

  8. The sampling site lies just above the Doushantuo cap carbonate , so the data basically forms an age constraint on the lower boundary of the Sinian ( Ediacaran ) System .

    采样点紧邻作为震旦系底界的盖帽碳酸盐岩之上,基本可以限定震旦系的底界年龄。

  9. The affinity of phosphatized globular fossils , one of the important types in the Ediacaran Weng'an biota , was first interpreted as that of green algae .

    磷酸盐化球状化石是埃迪卡拉纪瓮安生物群中的主要化石类型。

  10. A highly diversified macrofossil assemblage was discovered from the Jiucheng Member of the uppermost Ediacaran of Jinning and Jiangchuan areas in eastern Yunnan .

    滇东地区旧城段形态多样的宏体藻类化石的发现,进一步表明埃迪卡拉纪末期存在后生植物的多样化发展。

  11. Most ambitiously , Dr Zhu , Dr Xiao and their colleagues hope to drill right through several fossiliferous sites in southern China where Ediacaran rocks turn seamlessly into Cambrian ones .

    朱博士、肖博士及他们的同僚们最有抱负的是,希望在中国南部地区,在埃迪古拉纪岩石与寒武纪岩石交替的化石遗址中进行钻测。

  12. I discussed Ediacaran paleogeography evolution in Mid-Yangtze in the paper . Thought that the Mid-Yangzi area Ediacaran discipline lithic facies ancient geography pattern is inherits in the Southern China discipline foundation and develops .

    讨论了中扬子地区伊迪卡拉纪古地理演化,认为中扬子区伊迪卡拉纪岩相古地理格局是在南华纪基础上继承和发展起来的。

  13. The redefined Sinian System in China , bounded by the base of the cap carbonate ( the lowermost Doushantuo Fm . ) just above the Nantuo diamictite , quite corresponds with the Ediacaran System .

    我国修定后的震旦系与埃迪卡拉系完全相当,底界以南沱冰碛岩之上盖帽碳酸盐岩的下界为界。

  14. They have found that the proportion of ¹² C - a light isotope of carbon that is more easily incorporated by living organisms into organic matter than its heavy cousin , ¹³ C - increased on at least three occasions during the Ediacaran period .

    他们已经发现,有机体中的碳12比其同胞碳13更易于与有机化合物结合,在埃迪卡拉纪可增加至少3倍。

  15. Other researchers have found fossils of algae and wormlike creatures in rocks in northern China that pre-date the end of the Marinoan glaciation , 635m years ago , which marks the boundary between the Ediacaran and the Cryogenian period that precedes it .

    其他研究者已在中国北部地区的岩石里发现水藻化石和蚯蚓类生物,是6.35亿年前的冰河世纪末,标志埃迪卡拉纪和成冰系时期的界限前移。

  16. And , at several spots on the planet , the Ediacaran lagerst ? Tten , named after the Ediacara hills of Australia where the first example was found , harbor strange Precambrian soft-bodied fossils and animal burrows , including evidence for early bilaterians .

    而分布在地球上数个地区的艾迪卡拉特异埋藏点(名自首次发现的澳洲艾迪卡拉山)里面藏有奇妙的前寒武纪软体化石与虫穴,包括早期两侧对称动物的证据。
