From stratigraphical analysis the average tungsten content in stratum of Ganzhou is 9.53ppm, somewhere more than 12ppm. This is more than 7 times over the world average value of 1.3 ppm.

据统计，赣南地层中钨的富集为9.53 ppm，部分地层高达12ppm以上，为世界地层中钨平均值1.3 ppm的7倍以上。

E. , the east - central stratigraphical district and western stratigraphical district.

鄂尔多斯盆地奥陶系可分为两个地层分区，即中东部地层分区和西部地层分区。

As a branch of stratigraphy, sequence stratigraphy was established on the basis of seismic stratig...

层序地层学作为地层学的一个分支学科，是在地震地层学的基础上，根据北美海相被动大陆边缘盆地的研究成果而发展起来的。

Cyclostratigraphy was born in 1980s as a subdiscipline of stratigraphy. Based on the Milankovitch theory, outcrop sections and cores are analyzed with methods such as geochemistry, spectrum analysis, and time-sequence analysis to study the complex responses of orbital forcing to sedimentary records.

旋回地层学作为一门独立的地层分支学科诞生于20世纪80年代，它以米兰科维奇天文轨道旋回为理论基础，以露头剖面、岩心等为研究对象，应用地球化学、光谱分析和时间序列分析等方法，研究天文轨道参数周期性变化在地层记录中的沉积响应。

With the ordinal addition of dispersed clay particles,oil drops,conducting matrix grains,laminated shale to water and successive integration over the addition of a single inclusion,generalized matrix-conducting pore combination model in laminated and dispersed shaly sands is established.

通过两组分散泥质砂岩岩样实验测量数据和一组层状泥质砂岩测井资料及实际测井资料的计算，表明本文给出的电阻率模型既适用于分散泥质砂岩地层解释又适用于层状泥质砂岩地层解释，同时，还适用于含有分散粘土和层状泥质的混合泥质砂岩地层解释。

Distribution characters of the soil stress and its distortion were analyzed. The interaction relation among the character, and earth parameters and timbering parameters were clarified, and properties of region and structure of overlay soil for tunneling face was posted.

全面分析了围岩的应力与变形的分布特征及其变化规律，阐明了地层变位以及应力与地层参数、支护参数的相互关系；揭示了隧道上覆地层的区域性及结构性特点。

Fingering often occurs in waterflood development low permeability reservoir because of non-Darcy flow, which is weakened with formation dip increasing.

结果表明，由于非达西渗流的影响，注水开发时容易发生指进现象，而地层倾角的增大可以削弱指进；地层原油粘度的增大会增强开采难度，而地层渗透性能的改善会使油井产能提高。

Since Tertiary, the global eustatic level kept falling while transgression in the SCS remained expanding, indicating that local sea-floor spreading and subsidence acted as a leading role in the study area.

本文根据南海东部石油公司提供的钻井岩芯和地震剖面资料，作了岩石地层学、层序地层学和地震地层学分析，识别出东沙、西沙和南沙的淹没事件。

Currently, in the oil-field exploitation, existing the phenomenon of garbling the lack thickness of stratum with vertical fault-throw in well logging identification of strata while meeting fault in drilling well. In most case, consider the lack thickness of stratum which contrast the imperfection geologic strata thickness to the well and the well as the fault-throw. The method which using very popular in oil-field exist shortages, it very much easily lead people into the areas of misplay. especially when the seismic person and geology confirm the fault-throw, It often appear inconsistent instance.

目前，在油田开发中钻井钻遇断层时，地质人员时常存在将测井分层与相邻井对比时缺失地层厚度与铅直地层断距混淆的现象，很多情况下把井与井对比缺失地层厚度等同于断层断距等，这些现今在油田非常流行的用法存在一些不足之处，容易把人们引入一些认识上的误区，特别是在地震与地质人员进行断层断距的确定时，经常出现矛盾的情况。

Researches to the gold-bearing quality of sedimentary and magmatic rocks show that most of these rocks have more gold content than the average of the upper crust. Further evidences are quoted to support the view that fluids exist in shallow crust have the ability resolve some gold. Moreover, in the convergent compression, deep melting of the lower lithosphere can bring some Au and mineralization materials and move up to upper crust. Regional faults, which formed in geosynclinal and diwa periods, controlled the partial distribution of intrusions and gold mineralization belts, i.e.

区域地层和岩浆岩的含金性表明，岩浆岩和大部分地层均具较高的金异常含量，而进一步的研究表明浅部地壳的流体对地层中的金具一定的溶解和搬运迁移能力；而在汇聚挤压构造体制下由深熔作用生成的岩浆可以从岩石圈深部携带部分金和其它成矿物质并迁移到地表浅部，地槽期和地洼期形成的区域断裂构造共同控制了中新世岩浆的侵入和金成矿带的分布。

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
