These mainly are Pteridophyta and Gymnospermae and plant species are frequent ones in lower and middle Jurassic, basically in corresponding to Coniopteris-Phoenicopsis flora group of Lower-Middle Jurassic coal-bearing strata widely distributed in China.

植物化石中以蕨类和裸子类为主，植物总体种群为中外早中侏罗世地层中常见分子，基本上相当于我国早中侏罗世广泛分布的含煤地层所含Coniopteris-Phoenicopsis植物群。

Synchronous parallel-type refers to the oil-gas system formed a relatively independent oil-gas system in the same stratigraphic range. Heterochronous polymeric-type refers to the stratigraphic and regional range overlaid in oil-gas systems which formed in different period. Synchronous cross-type refers to a mode of regional ranges crossed of two oil-gas systems.

同期并列式指含油气系统在同一地层范围形成彼此独立的含油气系统；异期叠合式是指不同时期形成的含油气系统地层范围，地区范围重叠的组合方式；同期交叉式是指两个含油气系统地区范围交叉的组合方式。

In an attempt to summarizing the previous work, and analyze the hydrometeorological, geological and hydrogeological condition of Beitang reservoir, in Tianjing city, the hydraulic conductivity of the reservoir bottom stratum and its spatial random distribution were determined by using field hydro-geological investigation and grain size analysis in the laboratory.

本文以天津市北塘水库为研究对象，在总结前人研究成果、分析北塘水库地区的水文气象、地质、水文地质条件的基础上，通过野外水文地质勘探、取样与室内颗粒分析实验相结合的手段，获取了库底地层的渗透系数，探讨了库底地层渗透系数的空间随机分布。

The thickness of Badong formation is approximately 820m at least and 1420m at most with a tendence of gradual incrassation from east to west.

巴东组地层在秭归、巴东、巫山、奉节等4个地区的总厚度最小约为830m，最大约为1420m，自东而西地层总厚度具有逐渐增大的趋势。

Because the major seismic reflections have chronostratigraphic significance, and the isochronic correlation is relative, the seismic data may help us to correlate subzones of a nonmarine reservoir under certain conditions.

但是，由于主要地震反射同相轴具有年代地层意义，而且地层等时对比是相对的，因此，在一定条件下，利用地震资料可以进行陆相薄互层储层小层对比。

The rock formation and isochronic sequence stratigraphic correlation framework have been set up which shows the sedimentary sequence in both Luxi and Jiyang depression is similar to each other, being of the same sequence architecture of'duality structure'but a bit differences in sedimentary system.

以多重地层划分及层序地层学理论为指导，运用沉积学、古生物学、地球化学、地球物理学方法和资料对研究区石炭二叠纪陆表海聚煤盆地的沉积层序进行了综合识别分析。

With synthetic application of high resolution sequence stratigraphy and facies controlled cycle isochronous correlation technology, both of which are delicate sequence stratigraphic correlation methods, Es2 Member in Shanghe oil field is isochronously classified and correlated.

在对比了高分辨率层序地层学和相控旋回等时对比技术的基础上，认为二者同属于地层精细划分方法，在本质上没有区别，在层序划分级别上有可比性，在实际运用中各有其优缺点，在同一研究中可以结合运用。

The water in the pores of the undercompaction layer undertook a part weight of the super jacent stratum and resulted in the ultra-pressure of fluid in the pores.

具欠压实地层的孔隙水承担了部分上覆地层的重量，从而形成孔隙流体超压。

The metamorphic rocks of the area consist of granulite, plagioclase-gneis, biotite leptite and various kinds of schists of granulite to amphibolite facies By reconstruction, this metamorphic series is composed of three original formations which inciude five originai rock types: intermediate-acid volcanics formation at the bottom basic-felsic bimodae volcanits formation in the middle and basic-andesitic-felsic volcanics formation at the top...

区内太古代变质岩系广泛发育，其下部为深变质的麻粒岩相地层，上部为中深变质的角闪岩相地层，后者产出红透山式铜锌矿床多处，以及张胡子沟铜矿床和大荒沟硫铁矿床等一系列块状硫化物矿床(图1)。矿石中铅同位素年令为25～26亿年，在形成时代上可以和鞍本地区鞍山群对比。

In addition, it is one important basic research for exploration and development of lithologic oil and gas reservoirs in deep-water areas.

深水细粒沉积层系的层序地层单元细分和对比，是建立合理的层序地层格架的关键，也是进行深水区岩性油气藏勘探开发的一项重要基础研究工作。

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.
