1.The comparison of Cenozoic basalts and their mantle xenoliths from both sides of the Taihangshan gravity lineament reveals that: (1) Cenozoic basalts from western and eastern North China display opposite temporal trends, suggesting lithospheric thinning in western North China during the Cenozoic and lithospheric thickening in eastern North China; (2) The lithospheric mantle in the west is mostly Late-Archean to Proterozoic in age, whereas that in the east has a modern age with minor Proterozoic age; (3) The crust mantle transition in the west is considerably thicker than in the east, probably due to different extents of magmatic underplating.
摘要通过对比华北太行山重力梯度带两侧新生代玄武岩及其中幔源包体的成分，发现：(l)华北东、西部新生代玄武岩具有相反的演化趋势，说明新生代以来西部岩石圈逐渐减薄，而东部岩石圈逐渐加厚；(2)西部岩石圈地幔组成相对复杂，年龄多为晚太古代－元古代；而东部岩石圈地幔组成相对单一，年龄多为现代值，少数为元古代；(3)西部壳幔过渡带较厚而东部较薄，反映两地不同的岩浆底侵作用程度。
2.There are different tectonic character of Jiuquan Basin in Cenozoic and Mesozoic: it was a foreland basin in Cenozoic and was a downfaulted basin in Mesozoic. So it is a superimposed basin and there are two tectonic units from Mesozoic to Cenozoic.
酒泉盆地的新生代与中生代有明显不同的构造特征，酒泉盆地的新生代以前陆盆地为主，而中生代为断陷盆地，中新生界在空间上构成了上下两个构造层，属于叠合盆地。
3.Abstract: On the basis of systematic synthesis, and study on the recent comprehensive geophysical-geochmical data, such as seismic, gravimetric, magnetic, electric, comprehensive logging, radiometric survey, this paper divides the second-order tectonic units of the basement of Mezo-Cenozoic sedimentary basins, the structure and basement lithology of sedimentary basims, and ascertains the sequential structre, occurrence depth, thickness and spatial distribution of the basin cover, and analyses the uranium source condition of the basement and provenance area, and the uranium content of Cenozoic strata, as well as the mobilization and migration of uranium in Cenozoic cover.
文摘:本文全面系统地整理和分析研究了巴楚地区地震、重磁、电法、综合测井、放射性测量等最新的综合物化探资料，划分出了该区中新生代沉积盆地基底的次级构造单元、盆地结构构造以及盆地基底岩性；查明了盆地盖层的层序结构、埋深、厚度及空间展布；分析了蚀源区和基底岩性的铀源条件和新生代地层的含铀性及铀的活化迁移规律。
4.In South Ⅳ and South Ⅴ sags, however, a secondary hydrocarbon generation occurred during Cenozoic due to thicker Cenozoic sediments
后续埋藏过程对大部分地区二叠系烃源岩的生烃没有明显影响 ,但南四凹及南五凹地区二叠系烃源岩因新生界沉积厚度较大而于新生代再次生烃
5.whereas the Meso Cenozoic first order sequences are consistent with the Meso Cenozoic synthems, which reflects the most important role of tectonic activities in formation of first order sequence during the foreland stage of the Tarim basin.
中、新生界地层的1级层序与构造层相符，反映了塔里木前陆盆地阶段构造活动对层序形成起着决定性作用。
6.On the basis of analysing the gas well productivity and test situation at home and in accordance with the geological charateristics and practical experience of Cenozoic shallow gas reservoirs,the single productivity production (or blowout)—pressure build up testing combination test method adopted in the productivity test in Cenozoic shallow gas reservoirs is proposed out.
在分析国内气井产能、测试现状的基础上，根据新生界浅层气藏的地质特征和实践经验，提出在新生界浅层气藏产能测试中应采用单产量生产（或放喷）—压力恢复试井组合测试方法；
7.Based on available data, the study on regional structure, sedimentary reservoir and source rock characteristics shows that the basins in South China Sea had experienced sedimentary evolution in faulting period and depression period, deposited thick Cenozoic formation, upwardly developed alluvial fan facies, river-lake facies→coastal swamp facies→coastal facies, neritic facies and bathyal deposit system, regionally had 3 source rocks of Eocene, Oligocene and Miocene, 3 reservoirs of pre-Cenozoic basement buried bill, Oligocene sandstone and Miocene reef, with Pliocene and Pleistocene neritic facies and bathyal shale as regional caprock.
摘要以现有资料为基础，通过对区域构造、沉积储层、烃源岩特征等基础石油地质条件研究，认为南海海域各盆地经历了断陷期和坳陷期沉积演化，沉积了巨厚的新生代地层，自下而上发育了冲积扇相、河湖相、滨岸沼泽相、滨海相、浅海相、半深海相沉积体系，区域上存在始新统、渐新统和中新统3套烃源岩，前新生代基岩潜山、渐新统砂岩、中新统生物礁3套储层，区域盖层为上新统和更新统浅海－半深海相泥岩。
8.Song-liao basin is a large Mesozoic-Cenozoic continental depositional basin developed in Xingmeng-Jihei Hercynian fold belt. Its basement is mainly composed of Paleozoic epimetamorphic rocks and the cover mostly consists of Cretaceous graywacke and organic shale formation,as well as Cenozoic loose elastic accumulations.
松辽盆地是在兴蒙－吉黑海西褶皱带上发育起来的中、新生代大型陆相沉积盆地，基底主要为古生界浅变质岩，盖层主要是白垩系杂砂岩－有机页岩建造和新生界疏松碎屑堆积。
9.Thirdly, the REE distribution from samples of the Cenozoic and Mesozoic is greatly similar, suggesting that the conversion of geological patterns occurred from the Mesozoic to Cenozoic and some sags of the Mesozoic became arch area of source in the Paleogene.
③新生界样品与中生界样品的REE分布模式具有很大的相似性,从一个侧面反映了济阳坳陷中生代与新生代的构造格局的转变,中生代接受沉积的部分洼陷区至古近纪成为供给物源的凸起区。
10.In reservoir, there is mainly Mesozoic Cenozoic reservoirs in basins of Central Asia, but basins of western China have not only Mesozoic Cenozoic reservoirs but also Palaeozic reservoirs.
从储集岩特征来看 ,中亚地区含油气盆地以发育中—新生界储层为主 ,而中国西部大部分盆地不仅广泛分布中—新生界储层 ,具有发育古生界储集层的优势 ;
