白垩

The transfer of these orogenesis types occurred respectively in the early-middle Triassic and late Cretaceous.

造山类型的两次重大转换分别发生于早、中三叠世与晚白垩世。

New observations indicate that Jingangtai volcanic rocks unconformably overlie the early Cretaceous Shangcheng Pluton, hence they must have not formed in the Jurassic.

新的地质观察表明，其不整合于早白垩世商城岩体之上，不应当归属为侏罗纪。

Archeology tells us that the Late Cretaceous was the last one the Mesozoic world, it has a large reptiles dominated the earth's sudden disappearance to an end; Paleocene is the new generation of the first world, it replaced the rapid development of mammals opened the earth and the latest scene in the history of biological evolution.

考古学告诉我们，晚白垩世是中生代最后一个世，它以曾经主宰大地的大型爬行类的突然消失而告终；古新世是新生代的第一个世，它以取而代之的哺乳类动物迅速发展而拉开地球和生物演化史的最新一幕。

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。

There is a short time exposing facebetween them. At the contact, the Paleocene clastic rock of Zongshan Formation overliesdirectly on the latest Cretaceous shelf carbonate rock.

古新世的砂砾岩直接覆于晚白垩世的陆棚碳酸岩盐沉积之上，沉积的重大转变代表一次区域构造运动。

The results indicate that the extension of the Hefei basin possibly started in the mid Early Cretaceous and lasted to the Paleogene.

结合同位素年代学资料综合分析认为，合肥盆地伸展活动的起始时间为早白垩世中期，持续至古近纪末。

Research on clay mineral s from the Jurassic-Cretaceous in Northeast of the "Eastern Plateau",China indicates that the change in clay mineral assemblage and content was related with paleoclimate,source and paleography,and IC did not vary with the depth of the stratum.

通过对"东部高原"东北部地区中侏罗统—白垩系中黏土矿物分析，结果显示黏土矿物的组合及含量变化能够较好反映当时的气候、物源以及古地理变化；同时，伊利石结晶度不具有随地层深度发生变化的规律。

The project will make full use of Cretaceous marine, terrestrial strata and paleontological records.

项目将充分利用中国大陆发育完好的白垩纪海相、陆相地层及古生物记录，通过松辽盆地白垩系科学钻探全岩芯取样和多学科综合研究的途径，着眼于厘定反映地质事件和气候变化的层位及标志和时间格架，解决高分辨率海、陆相沉积事件的精确对比，分析地层记录中气候标志和古生物类群的地理分布，集中研究陆地和海洋环境对同一事件的响应机制，重溯白垩纪地球表层系统重大地质事件过程及成因，探究陆相烃源岩大规模形成、陆地生物群更替与温室气候变化和碳循环之间的正/负反馈关系和机制等科学问题，为预测全球长时间尺度上的气候变化趋势提供科学依据。

The algae flourished from the Lower Permian to the Lower Cretaceous, some 140 million to 280 million years ago!!

蓬勃发展的藻类从早二叠世的早白垩世，有1.4亿至280万年前！

No evidence at present has been given to confirm that the Middle Jurassic plutonism is existed in the Beijing area.

北京地区中生代侵入活动发生在晚三迭世末－早侏罗世初、晚侏罗世－早白垩世两个阶段。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
