地层

Seismic stratigraphy is the study of stratigraphy and depositional facies as interpreted from seismic data.

地震地层学是按照地震资料解释进行地层学和沉积相的研究。

On the basis of analysis of the movement characteristics of horizontal layered foundation and the relationship between soil parameters and eigenvalues and eigenvectors of the soil system, frequency domainid entification method of the layered foundation parameters is suggested by correcting the deviation between the measured soil data and theoretical calculation results.

在分析水平层状地基运动特征的基础上，通过研究地层系统的特征值和特征向量与地层参数之间的关系，修正测量得到的数据与理论计算结果之间的偏差，建立了层状地基参数的频域识别方法。

Basing on the analysis of epicontinental sea carbonate platform sequence stratigraphy of Cambrian in north China, the paper puts forward 6 points which shall be noticed on the study of sequence.

根据对华北地台寒武系陆表海碳酸盐台地层序地层分析，提出了露头层序工作的方法以及应注意的六项问题。

The sedimentary formation can be summarized as epicontinental sea filling sequence, offshore debris lake basin sequence and inner continental lake basin sequence etc.

在此基础上，对沉积层序地层进行了探讨，划分出了陆表海、近岸碎屑湖盆和内陆湖盆等3个层序组以及18个沉积层序，建立了研究区层序地层学格架。

Through the investigation of massive literatural materials related to researching area,the thesis has carried out comprehensive analysis for the features of lithology and logging curves,on the basement of having clarified the regional geological background and epigeic geological characteristics.

本论文通过调研大量有关研究区的文献资料，在弄清了塔中地区的区域地质背景、构造作用史等地质特征的基础上，进行了岩性特征、测井曲线特征综合分析，将塔中地区下奥陶统地层划分为鹰山组和蓬莱坝组，并在此基础上进行了地层的进一步划分和对比，将鹰山组划分为鹰一~鹰四段。

The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

It always contains fractures、 poorly cemented or non- cemented fracted zone in real formations, moreover, some fractures are induced during drilling, so the formation around the well is not continuous.

实际地层本身含有裂缝、胶结差、甚至无胶结的破碎带，再加上钻井过程中的诱导裂缝，井眼周围的地层并不是连续的。

The strata between the carbonate rocks of the Chaguoluoma Formation (Devonian-Early Carboniferous) and carbonate rocks of the Xiala Formation consist mainly of clastic rocks with limestone, which are marked by glaciomarine deposits in terms of sedimentation and mixing of Gondwanan and Tethyan faunas in terms of fossils.

古生物群混生的现象为石炭纪—二叠纪的特提斯生物区与冈瓦纳生物区之间的地层和古生物对比建立了一座桥梁。永珠组中上部地层中同时产有牙形石和腕足类，牙形石的研究表明其时代为晚石炭世莫斯科期，而腕足类的研究则表明其为早二叠世萨克马尔期。

The original Seluohe Group contains at least four parts: Late Archean metamorphic rocks (zircon SHRIMP protolith ages 2517~2534 Ma), Late Paleozoic metamorphosed volcanic-sedimentary strata (zircon SHRIMP 252 Ma), Permian gneissic granitic complex (zircon SHRIMP 260 Ma), and Jurassic mylonitized granites (zircon SHRIMP 168 Ma).

原划分的色洛河群至少由4部分组成：新太古代变质火山－沉积地层（锆石SHRIMP年龄为2517~2534 Ma）、晚古生代变质火山－沉积地层（英安岩锆石SHRIMP年龄为252 Ma）、二叠纪片麻状杂岩体（锆石SHRIMP年龄为260 Ma）和侏罗纪糜棱岩化花岗岩（锆石SHRIMP年龄为168 Ma）。

Five types of traps, including compressional, extensional, shearing, gravitative and strata litholoical types, were divided on studying the feature of different tectonic movements , seismic sequences and depositional property in Wan an Basin.

作者在分析该含油气区地质构造特征、地层划分和沉积特征的基础上，划分了压缩型、伸展型、剪切型3 种构造类圈闭和重力、地层－岩性两种非构造型的圈闭，并选用南、北两条典型地震剖面模拟了典型圈闭形成过程及其与构造运动之间的演化关系，可为在该区中寻找同类型含油气圈闭和进行构造演化史的研究提供可靠依据。

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.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
