渐新世

从渐新世开始，柴达木盆地才进入强烈挤压的山间盆地阶段，并决定了柴北缘现今的构造格局。

The prototype basin in Jurassic was a weakly extending depression ; Begining Oligocene epoch , the basin was becoming intensively compressed and the structure distribution framework today was formed .

覆盖于穹丘上的沉积岩为渐新世侵蚀所截削

Oligocene erosion had truncated the sediments draped over the dome .

总结得出，在渐新世JAZMIN油田处于冲积平原，以河流相发育为主要特征。

The conclusion is that JAZMIN oilfield is in an alluvial plain with the main characteristics of river development .

形成深度约510km，形成环境不超过绿片岩相。大体生成于渐新世时期，约4020Ma之间。

The nappe structure was formed at depths of about 5-10km , largely in the Oligocene , and the formation environment did not exceed the low greenschist facies .

海盆中沉积物的厚度为300～1500m，时代为晚渐新世～第四纪，由此推测西南次海盆的扩张开始时间应该为早渐新世。

The thickness of the sediments in SW Subbasin is300 ~ 1500m and the age is late Oligocene-Quaternary , so the seafloor spreading age of SW Subbasin is about early Oligocene .

断块运动受统一应力场支配，早期（渐新世上新世）主压应力方向为NESW，晚期（上新世末第四纪）则转为NWSE。

Fault-block movement is controlled by the unified regional stress field . The principle compression stress direction was NE SW during the early neotectonic stage ( E_3 N_2 ) , while in the late stage ( the end of N_2 Q ) it 's become to NW SE .

渐新世太平洋板块以俯冲后撤作用为主，致使NW-SE向陆内扩张而形成一系列大型陆内伸展盆地，以及来源于软流圈地幔的玄武岩。

Controlled by the roll-back subduction belt of Pacific Plate during Oligocene , the NW-SE direction intracontinental spreading happened and a series of large intracontinental extensional basins and basalts derived from asthenosphere mantle were developed in this area .

东海陆架东部凹陷带渐新统砂岩锆石的U-P年龄表明陆架东部渐新世物源以元古代变质岩为主，其次为中生代母岩及少量太古代变质岩与古生代母岩。

The U-P dating data of zircons from Oligocene sandstones in the east of East China Sea shelf indicate that most zircon grains are Proterozoic , and then are Mesozoic , including sporadic Archean and Paleozoic ones .

所获得的新资料并不支持亚洲季风系统起源于约8Ma前这一观点，而认为东亚大约是在晚渐新世向季风气候转变这一假设更为合适。

The new data do not support the onset of the Asian monsoon system around 8 Ma . Rather , the new data led to a hypothesis that the transition to the monsoon climate system in East Asia occurred in the latest Oligocene .

A型俯冲始自中三叠世末，延续到渐新世初，持续了约180Ma，主构造期为中三叠世末。

From the middle Triassic to the early Oligocene , the A-type subduction lasted about 180 ma and major tectonic stage is the middle Triassic . In the lower Yangtze region , there exist good oil generating , bearing and covering bed assemblages in the marine strata .

南苏门达腊盆地是典型的弧后裂谷盆地，其演化经历了4大构造期：始新世中期到渐新世早期为裂谷发育期；

The South Sumatra Basin is a typical back-arc rift basin .

北部湾盆地在中始新世至早渐新世是一个湖泊。

Beibu Wan Basin was a lake in the middle Eocence-Lower Oligocene .

第二期发生在渐新世末期。

And the second occurred at the end of Oligocene .
