| 1. | Paleocene the oldest epoch of the tertiary , 65 - 55million yesrs ago 古新世:第三纪最古的年代, 6500万5500万年前。
|
| 2. | Research on some favorable phase belts about the reservoir caprocks of cretaceous - paleocene in jianghan basin 下第三系储层盖层有利相带研究
|
| 3. | It is the first time to apply this method to study sedimentary facies of the paleocene - miocene in the qaidam basin 这是首次将定量的沉积相研究方法应用于柴达木盆地的古新统至中新统。
|
| 4. | The paleocene epoch , 63 millions ago , is a crucial time in the history of mammals , it was a world without dinosaurs 古新的世纪, 63成千上万前,是关键的时光在哺乳动物的历史上,它是一个世界没有恐。
|
| 5. | From paleocene to miocene , the sedimentary facies evolved from the extensive alluvial fan to the braided fluvial river environment 从古新世到中新世,柴达木盆地北缘经历了由大规模冲积扇沉积到辫状河沉积的演化过程。
|
| 6. | Paleontological studies showed that modern avian groups probably first appeared in the paleocene and experienced an explosive radiation in the early cenozoic 古生物学研究表明,现生鸟类的最早出现是在古新世,而爆发性辐射演化发生在新生代早期。
|
| 7. | The mesozoic primary hydrocarbon accumulation has been heavily damaged by the denudations at latest middle jurassic and latest cretaceous and the faulting from paleocene to eocene 中侏罗世末期、白奎纪末期的地层抬升剥蚀,以及古始新世的断裂活动对中生代形成的原生油气藏破坏作用明显。
|
| 8. | Only ten million years later , at the end of the paleocene , they had occupied a large part of the vacant ecological niches , often competing with giant carnivorous birds , especially in south america 只十百万年后,在结尾的古新,他们占领了空置生态学适当位置的一大部份,经常竞争与巨型肉食鸟,特别是在南美洲。
|
| 9. | The sedimentary systems were alluvial fan - braided fluvial river - lacustrine depositional systems during the paleocene - eocene , and braided fluvial river - lacustrine depositional systems during the oligocene - miocene 古新世始新世发育冲积扇辫状河湖泊沉积体系,渐新世中新世发育辫状河湖泊沉积体系。
|
| 10. | The study results can be summerized as following aspects : ( 1 ) the basic settling curve of this basin was broken - line shape of seven sections in which upper jurassic , lower cretaceous , eocene , oligocene and neogene corresponded with the decline ones representing five episodic clear subsidences of this basin , late cretaceous to paleocene and early miocene corresponded with the rising ones reflecting the uplift and denudation of this basin . ( 2 ) the subsidence of this basin migrated from the east to the west , from mesozoic to cenozoic 研究表明: ( 1 )北黄海盆地的基本沉降曲线型式为7段折线状,其中晚侏罗世、早白垩世、始新世、渐新世、新近纪为曲线下降段,代表盆地5幕较明显的沉降;晚白垩世古新世以及中新世早期为曲线上升段,反映盆地的抬升剥蚀。
