始新世

The phase of rift basin formed the primary source rocks and reservoir and seal. Triassic-Jurassic Pucara Group and Cretaceous Chonta Formation generated a mass of hydrocarbons in Paleocene-Eocene (60-45Ma) and Miocene (15-5Ma), respectively.

盆地内主要的烃源岩及储、盖组合均发育在裂谷盆地阶段，三叠系—侏罗系Pucara群和白垩系Chonta组2套主要烃源岩的排烃高峰期分别是古新世—始新世（距今60～45 Ma）和中新世（距今15～5 Ma）。

Eocene The second oldest epoch of the Tertiary period, 55-38 million years ago.

始新世：属第三世后的第二世，从5500万年前到3800万年前。

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。

A large, coin-shaped, fossil foraminifer of the genus Nummulites, widely distributed in limestone formations from the Eocene Epoch to the Miocene Epoch of the Cenozoic.

货币虫货币虫体形大而呈硬币状，化石有孔的虫，从始新世到新生代的中新世广泛分布在石灰岩地层中

A family of North American Indian languages spoken by the Nootka and other peoples of Washington and British Columbia.

雷兽类一种已绝迹的雷兽属和其它相关属类的有蹄食草哺乳动物，生长于始新世和渐新世，类似于犀牛

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。

The former began to migrate toward fresh water environment in late Cretaceous,but portion of them still remained in sea water till late Eocene;the latter began to migrate toward fresh water in Paleocene and lost its records in sea water.

前者在晚白垩世开始向淡水环境迁移，但仍有部分留在海水中，一直延续到晚始新世；后者在古新世时开始迁向淡水，并在海水中失去记录。

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.

栲属在地质历史上有着比现在广泛的分布，最早、最可靠的栲属化石记录发现于始新世地层，栗亚科化石在古新世就有发现，化石记录表明栲属起源的时间不晚于古新世，所有的壳斗科及栲属的化石都发现于北半球，现代分布也主要在北半球，壳斗科及栲属起源于北半球可以确认，由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足，具体的起源地尚不能肯定。

On the basis of analyzing regional structure and evolution characteristics, It is considered that undergoing 3 evolutions of Eocene-Oligocene, Miocene and Pliocene exploration, Burma central basin Formed in Tertiary and can be divided into 2 secondary grade structural units, i.e. western deep depression and eastern shallow depression, and 11 third grade structural units, such as Irrawaddy sag, Prome sag, Salin sag, Chindwin sag, Hukawng sag, Putao sag, Shwebo sag, Inlelake sag, Salween sag, Sittang sag and Pegu upwarping.

基於对区域构造特徵和演化的分析，认为缅甸中央盆地形成於第三纪，经历了始新世－渐新世、中新世和上新世三期构造演化，可划分为西部深坳区和东部浅坳区2个二级构造单元及Irrawaddy凹陷、Prome凹陷、Salin凹陷、Chindwin凹陷、Hukawng凹陷、Putao凹陷、Shwebo凹陷、Inlelake凹陷、Salween凹陷、Sittang凹陷、Pegu凸起等11个三级构造单元。
