The oilbearing analysis of Event Strata indicates that sealevel rising anoxic Event Association is favorable to producing oil, while the sealevel dropping turbidity Event Association may be favorable to reserving oil and gas.

事件地层含油性分析表明，研究区海平面上升-缺氧事件组合是有利的烃源岩，海平面下降-浊流事件组合具有一定的储集意义。

Tracksites occur exclusively throughout several stratigraphic levels of a thick, mixed-affinity, lagoonal-terrestrial sequence known as the Upper Red Formation in north central Iran and within a continental series deposited in the southern Caspian area in north of the country. The tracks from the Upper Red Formation are mainly artiodactylan type, attributed to several gazelle sized species due to their small size, and other tracks attributed to small, medium and large sized mustelid and felid carnivores.

足迹化石在伊朗中北部分布在一套被称为上红组的厚层、混杂的泻湖－陆相地层序列的数个层位中；在伊朗北部的里海地区南部，则位于一套陆相沉积序列中：产自上红组的足迹以偶蹄动物类型为主，由于个体很小，可归入几种像羚羊一样大小的种；其他足迹则分别归人小型、中型和大型的触科和猫科食肉动物。

Through the analysis on geochemistry of palaeohydrology,we can know the origin of the oilfield water and then conclude the geofactor and the geochemical factor of the formation water.Through the study and the comeback of the palaeohydrodynamic field, we can judge the migration direction of the petroleum,the separate between gas and water,and the relation between the petroleum and the pool.

通过对油气成藏系统中古水文地球化学分析，可以了解油田水的起源，推断地层水化学成分形成的地质、地球化学作用；通过对古水动力场的恢复与研究，可以判识油气运移方向，气水分异状况，及其与油气藏形成的关系。

The electromagnetic responses of the finite size induction coils were evaluated, and the effects of the borehole mud ,casing pipe and radius of the induction coils were analyzed, the sensitivity of the electromagnetic response to the formation resistivity was checked against the crosshole measurements.

分析了金属套管井中有限尺寸线圈的电磁响应特征，讨论了井眼泥浆参数﹑套管参数和不同线圈尺寸对电磁测井响应的影响，考察了金属套管中电磁测井对地层电阻率变化的灵敏度。

While the nearly E-W-trending steeply dipping foliation belts and their corresponding structure of metamorphic strata are attributed to the second orogenic cycle.

而近东西向陡倾叶理带及相应的变质地层结构则属于后期造山旋回。

We can follow the history of life through the strata.

我们可以通过这一层层的地层跟踪生命的历史。

On that basis,combined with the trend surface analysis,the strata of the hanging wall and footwall of a fault were simulated.

采用inteoCace界面模拟出了断层面，并与趋势面相结合，构建了断层上下盘中的地层。

Based on these, we will measure isotopic composition of boron in biological fossils, such as shell, foraminifer et al. producing from Ynaghu Village, Yanqing Basin, Beijing at early Quaternary and from the sediment of salt lake in Tibetan at Quaternary, and then offer a reliable boron isotopic evidence for determining their source and survival surroundings.

在此基础上对北京延庆杨户庄第四纪早期地层和青藏高原第四纪盐湖沉积产出的有孔虫、贝壳类等生物化石的硼同位素组成进行测定，为确定它们的海陆相来源及其生存环境提供硼同位素证据。

A large, coin-shaped, fossil foraminifer of the genus Nummulites, widely distributed in limestone formations from the Eocene Epoch to the Miocene Epoch of the Cenozoic.

货币虫货币虫体形大而呈硬币状，化石有孔的虫，从始新世到新生代的中新世广泛分布在石灰岩地层中

And so the sea-level indicator based on such few foraminifera species is inadequate.

而且，由于胶结质有孔虫在地层中容易遭到破坏，所以以底栖有孔虫为基础恢复建立古海平面存在一定的局限。

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
