When data are insufficient,chemical analysis of REE can be used to rebuilt the lithofacies paleogeography of sequence. This method is favourable for the analyses of source,reservoir and cap rocks in the sequence framework.

在缺乏其它资料的情况下，应用稀土元素地球化学分析方法可恢复地层层序的岩相古地理，指导层序地层框架内油气生、储、盖条件的研究。

It has been caused much attention by many geologists at home and abroad. Based on the rich dinosaur resources in Henan Province, the author has obtained some important results through the scientific study and protection research of dinosaurs and,these results can help to discover more and more complete dinosaurs and other vertebrate fossils, to promote and raises the research level on the systematic paleontology and dinosaurs in Henan Province, and thus provides important scientific data on stratigraphy, paleogeography and paleoenvironment of Mesozoic basins, which can accelerate to build protection system at all levels and geological parks, all these can bring about a great advance in environment protection, tourism economy, agriculture, industrial production and social civilization.

以河南丰富的恐龙化石资源为依托，通过对恐龙化石的调查、发掘，科学特征和保护研究，不仅可获得一批重要的科研成果，促使发现更多更完整的恐龙化石和其它脊椎动物化石，促进和提升河南省恐龙研究水平，为中新生代盆地地层学和古地理、古环境研究提供重要的科学素材，而且可促进地质遗迹保护和地质公园建设，带动生态环境保护、旅游经济等方面的发展，达到促进地区经济效益增长和社会进步之目的。

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。

Based on detailed analyses on TOC,δ^13C org and HI from the lower Qingshankou to the upper Yaojia formations in Well Xu-22 of the central Songliao Basin, we have recognized three stages in the evolution of paleolimnology.

根据对松辽盆地中部X-22井青山口组－姚家组界线上下12.20m地层的TOC、δ^13C和HI等参数的分析，将该沉积期古湖泊的演化分为三个阶段。

These fossils not only enrich the content of the plant fossil assemblage in the study area but also provide an important paleontological basis for the determination of stratigraphic ages, stratigraph...

这些化石不仅丰富了本区植物化石组合内容，而且对地层时代的确定及与邻区的对比和沉积环境的恢复提供了重要的古生物依据。

中国山东省临朐县山旺中新世地层富含十分精美的古生物化石，已发现有10多个门类600余种。

Therefore , there are a lot of research work on sedimentary, well logging and high resolution sequence stratigraphy in the Upper Paleozoic in the Northeastern part of Ordos Basin in this paper.

因此，本文针对鄂尔多斯盆地东北部上古生界沉积、测井和高分辨率层序地层的研究展开了大量的工作。

The second episode is here re-defined as the "real" Linzizong volcanic successions that comprise, from bottom to top, Dianzhong, Nianbo and Pana Formations.

根据原始定义，后者才是"真正的"林子宗火山岩，并可由老至年轻分为典中组、年波组及帕那组等三个火山地层单元。

The study area is located in the W-E fault valley 68 km west to Yumenguan, on a residual hill peneplain of the North Mountain north to Suleihe billabong (90°～90°10′E,40°30′～40°34′N). There, the paleo-lacustrine sediments composing Yardang landform is deposited in the period of Middle and even Early Pleistocene.

玉门关西雅丹地貌位于玉门关以西68 km的疏勒河故道北面北山剥蚀残丘准平原的东西向断层谷地中（90°00′～90°10′E， 40°30′～40°34′N），该区雅丹地貌组成的古湖相地层被推测形成于中更新世甚至早更新世，中更新世末的新构造运动湖水向西撤退，随即被晚更新世的戈壁砾石层覆盖。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
