古新世

So, the timing of terrestrial strata can be defined from Eocene to Oligocene in Paleogene.

因此，尼玛盆地的陆相地层时代应为古近纪始新世－渐新世。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

Global physical events during the Late Miocene affected not only the European and Chinese Suoidea but also the environment.

猪类对比研究表明，从晚中新世初期到晚中新世末，中国与欧洲的古气候、古环境和猪类演化都受到了全球性自然变化的影响，有着相同或相似的发展经历。

Based on palynological data,we suggest that the retreat of the Tethys and Parat ethys from southern and Central Asia in Eocene and the uplift of Qinghai-Xizang Plateau in Miocene have largely shielded the monsoon climate northwestward,and have resulted in the Tertiary aridification in NW China.

文章依据孢粉资料讨论我国西北地区第三纪时期植被的演变情况，认为始新世时古地中海和副古地中海自南亚及中亚地区的撤退，以及中新世时青藏高原的隆起对东亚季风的屏蔽，都对西北地区的干旱化起了重大作用。

Artiodactyla generally divided into:(1) Ancient cloven-hoofed also known as sub-orders of ancient teeth, including the Eocene and Oligocene Some of the early cloven-hoofed, they already have two of the talus trochlear surface.

偶蹄目一般分为：（1）古偶蹄类或称古齿亚目，包括始新世和渐新世的一些早期偶蹄类，它们的距骨已具有两个滑车面。

Along the low-angle overthrust Early Permian marble and Early Triassic sandy slate were thrust southward over Paleocene-Eocene purplish red conglomerate of the Paleocene-Eocene Fenghuoshan Group and brick-red sandy conglomerate of the Oligocene Yaxicuo Group, forming many klippen of varying scales, and thick fault brecci.

沿低角度逆冲断层，早二叠世大理岩和早三叠世砂板岩自北向南逆冲推覆于古新统—始新统风火山群紫红色砾岩和渐新世砖红色砂砾岩之上，形成大量不同规模的飞来峰；沿主逆冲断层发育厚层断层角砾岩与断层泥，局部形成碳酸盐质糜棱岩。

The extinction or appearance of these Ostracoda always occurred in a short time interval, and can be correlated locally and globally, so they are of importance in bioeventstratigraphy. This article listed six such biological events in Qaidam Basin and discussed their causes. The extinction of Cetacella reflected temperature decrease at global scale and changes of palaeoclimate zones during the latest Jurassic and the earliest Cretaceous; The rapid decline of Cypridea in the earliest Cretaceous may be a result of the strikes of small planets; at the latest middle-Eocene Austrocypris became extinct, and at Oligocene Hemicyprinotus disappeared. These events related to the changes of the geological conditions at that time. The explosion of Cyprideis at the middle-Miocene was because the rise of Qinghai-Xizang Plateau which resulted in the dry climate and development of salt lakes.

这些水生生物的绝灭或发生均很迅速，在区域或全球范围内均可对比，具有生物事件地层学意义：Cetacella属的绝灭可能是侏罗、白垩纪之交全球性的古气候降温和气候带变化在柴达木盆地的反映；早白垩世之后Cypridea的迅速衰退是地外因素灾变的结果；中始新世晚期的Austrocypris的绝灭、渐新世Hemicyprinotus的绝灭都与当时地质条件的改变存在著内在的联系；中中新世Cyprideis的爆发推断是青藏高原隆升，导致气候乾燥、湖水咸化的结果；而晚更新世晚期1。

As to what happened to the Palaeocene fauna, the evidence points not towards an errant asteroid but to a giant burp from the oceans, which released a huge amount of methane.

至于古新世时代末期动物群到底发生了什么致使它们灭绝，有证据指出这是海洋的一个惊涛骇浪所散发出的大量甲烷气体所致使的，而并没有提到所谓的偏轨行星。

The study offers a "really big piece of evidence" to researchers trying to estimate Palaeocene climates, says Lisa Sloan, a climate scientist at the University of California, Santa Cruz.

这项研究提供了一个&很有说服力的证据&，这给研究者试着估计古新世的气候。丽萨说道--加利福尼亚大学气候科学家。

The heat flow evolution is associated with multi-episodic rifting processes.

古新世早期的大地热流值为83.6mW/m2，相当于现代活动裂谷的热流值。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
