侏罗系

Through statistical analysis of the rock mechanic properties of upper Jurassic and Cretaceous red mudstones, siltstones and sandstones in the middle Sichuan Red Basin, the range of their compressive strength, the features of the shearing strength and of the deformation curves are proposed in this paper.

文摘：对川中白垩系、侏罗系的泥岩、砂岩、泥质粉砂岩的抗压强度进行统计分析，得出红层岩石作为地基时抗压强度的范围值供设计参考，对泥岩、砂岩的其他力学性质进行了评价。

Based on the theory of Sequence Stratigraphy and the systematically analysis of strata which was closely focused on Lithostratigraphy, Biostratigraphy, Paleoecology Event Stratigraphy and Sequence Stratigraphy, four long-term base-level cycles can be recognized in the Mesozoic, each long-term base-level cycles can be further divided into intermediate-term to short-term base-level cycle. Eight intermediate-term base-level cycles are recognized in Mesozoic; Cenozoic can be divided into two structural base-level cycles, and can be further divided into seven long-term baselevel cycles.

应用层序地层学理论，在详细的岩石地层、生物地层、生态地层、事件地层和层序地层为核心的综合地层研究基础上，将中生界划分为四个长期基准面旋回，每个长期基准面旋回内部又可进一步识别出更次一级的旋回，侏罗系内部共可识别出8个次级旋回；根据钻井层序地层与地震地层划分结果，将北缘地区新生界划分为两个构造基准面旋回，其内部又可进一步划分为7个长期基准面旋回。

Although there is a little carbonite caused by some magmatic dikes in the CarboniferousPermiam coal, most Carboniferous-Permian coal has no great differences in vitrinite reflectance, crystalline indices, bulk specific gravity, hardness, and the content of velotile matter from the Jurassic coal, and both are super-anthracite.

区内石炭—二叠系煤与侏罗系煤除了前者含有一些由侵入体造成的天然焦或半焦外，二者均为超无烟煤，在镜质体反射率、煤晶核结构、显微硬度、挥发份和容重等方面上均没有明显的差异，说明区域变质是在煤系地层沉积之后发生的。

Gray-black oil shale and black charcoal shale were high quality source rocks in Jurassic system comparatively.

灰黑色油页岩及黑色炭质页岩是侏罗系中的优质烃源岩。

The phase of rift basin formed the primary source rocks and reservoir and seal. Triassic-Jurassic Pucara Group and Cretaceous Chonta Formation generated a mass of hydrocarbons in Paleocene-Eocene (60-45Ma) and Miocene (15-5Ma), respectively.

盆地内主要的烃源岩及储、盖组合均发育在裂谷盆地阶段，三叠系—侏罗系Pucara群和白垩系Chonta组2套主要烃源岩的排烃高峰期分别是古新世—始新世（距今60～45 Ma）和中新世（距今15～5 Ma）。

Four potential exploration targets are: Drape and extruding anticline traps in the source rock drainage area in Chonta Formation in central-western basin; Traction and extruding anticline traps in the source rock drainage area in Pucara Group in central-southern basin; Pucara Group carbonate traps in central basin; Upper Cretaceous lithologic traps and Upper Paleozoic structural-stratigraphy traps in the northern and eastern exploratory area.

有潜力的勘探领域包括中西部白垩系Chonta组烃源岩供油区域的披覆和挤压背斜圈闭，中部和南部侏罗系Pucara群烃源岩供油区域的牵引背斜圈闭和挤压背斜圈闭，中部的Pucara群碳酸盐岩圈闭，北部和东部成熟探区上白垩统岩性圈闭和上古生界构造-地层圈闭。

In order to discuss the relationship of coal measures and uranium deposit, extensive field exploration and systemic indoor analysis were conducted.

鄂尔多斯盆地东胜地区侏罗系煤与砂岩型铀矿在空间上密切共存，为探讨煤与铀矿的关系，进行了广泛的野外调研和系统的室内分析。

Later of Yanshan movement is main period of oil-gas migration and congregation,it is also main period of coalification in Permo-Carboniferous system ^ Triassic system and Jurassic system.

燕山晚期是盆地油气运移和聚集的主要时期，也是石炭—二叠系、三叠系及侏罗系的煤化作用的主要时期。

Clinging to life on an offshore crag, a tuatara looks little different from his Jurassic relatives.

死抱着生命在海面上的峭壁，一只新西兰产的大蜥蜴看起来有点不同，从它的侏罗系的亲属。

死抱着生命远洋危岩，一只新西兰大蜥蜴看起来有点不同，从它的侏罗系亲属。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
