查询词典 Jurassic

In Jurassic, the western, eastern and northern boundary of the basin had changed in varying degrees, except the south- Qinling orogenic belt rising in Indo-Chinese epoch, which is an always limited boundary. The western of the basin is limited by west-edge thrust nappe belt which formed in early and mid Jurassic.

The Chepaizi-Mosuowan paleo- uplift of N-E extending was shaped with the uplift ing of hinterland of Junggar basin during the Mid-Late Jurassic, which changed the structural framework of monoclinal hinterland of the basin, forming quite a few litho-stratigraphic traps of Mid-Upper Jurassic distributed along both sides of Chemo uplift .

侏罗纪中晚期，准噶尔盆地腹部隆升，形成北东向展布的车莫古隆起，改变了盆地腹部单倾的构造格局，形成沿隆起两翼分布的大量侏罗系中上统岩性圈闭与地层圈闭，为油气成藏提供了有利的场所。

In the Triassic-early Jurassic, the emplacement mechanism of monzonitic granite and orthoclase granite is dominated by tectonic extension and the diapirism is strong. The strong balloon swelling is dominant and tectonic extension is subordinate during the emplacement mechanism of early Jurassic alkali granite.

晚三迭世－早侏罗世二长、正长花岗岩体就位过程中构造扩展机制起主导作用，岩浆底辟作用也较强；早侏罗世碱性花岗岩体岩浆就位过程中以强力的气球膨胀作用为主，构造扩展机制为辅。

The tectonic evolution of southern Junggar basin can be classified into seven stages: stage of intracontinental rift from middle Periman to late Late Carboniferous; stage of weak extension and peneplane from late Permian to early Triassic; stable depression stage in middle-late Triassic; maximal basin formation phase in the setting of weak extension in early-middle Jurassic; inactive depressed basin formation phase in thrust setting in middle-late Jurassic; stable depression stage in Cretaceous and Eogene; foreland depressed basin formation phase in thrust setting in Neocene and Quaternary.

准噶尔盆地南缘晚石炭世以来盆地构造演化可划分为七个演化阶段：晚石炭世—中二叠世陆内裂谷作用阶段；晚二叠世到早三叠世处于弱伸展-稳定坳陷作用阶段；中、晚三叠世准平原化作用阶段；早、中侏罗世为弱伸展背景下广盆形成阶段；中、晚侏罗世冲断背景下的坳陷盆地形成阶段；白垩纪到古近纪弱伸展背景下的稳定坳陷盆地形成阶段；新近纪—第四纪为冲断背景下的前陆坳陷盆地形成阶段。

And the late Triassic bimodal association reflects the characteristics of intracontinental rift setting, the early Jurassic Raohe ultramafic - mafic rock - pillow lava association represent the environmental characteristics of oceanic island, magmatic arc association represent the characteristics of island arc and active continental margin with the background of the plate subduction, middle Jurassic syn-orogenic granodiorite-granite association reflects characteristics of matching and orogensis after continental accretion.

其中晚三叠世双峰式组合反映了板内裂谷成因特征，早侏罗世饶河超镁铁质-镁铁质岩-枕状熔岩组合代表了洋岛环境特征，岩浆弧火成岩组合代表了板块俯冲背景下岛弧和活动大陆边缘特征，中侏罗世同造山花岗闪长岩-二长花岗岩组合反映了陆缘增生后拼贴造山的成因特点，它们总体上代表了由被动陆缘裂向活动陆缘转化并最终发生陆缘增生带拼贴造山的一个演化过程，其间伴随有被动陆缘深海盆地沉积、活动陆缘弧后前陆盆地沉积和陆相类磨拉石建造

This study was only focused on the No.Ⅰore body. Based on detailed logging and dating results, it is considered that mineralization of the Cu_Au porphyry occurred in Late Jurassic. The formation of the ore body is related to the Late Jurassic augen quartz phenocryst_bearing hornblende_quartz diorite porphyrite intrusion（J3δομ）.

通过对雄村铜金矿床Ⅰ号矿体详细的地质编录和测年成果，发现雄村斑岩型铜矿床形成于晚侏罗世，矿体的形成与晚侏罗世侵位的、含眼球状石英斑晶的闪长玢岩（J3δομ）有关，成矿岩体呈不规则的岩枝状，全岩矿化，岩体中Au的平均品位大于1g/t，Cu含量大于0.7 %。

Through investigation and analyses of sedimentary settings especially the provenience of sediments, the Sinian-Jurassic sedimentary strata exposed in the study area have been recognized as Sinian-Lower Triassic passive continental marginal sequences and the Middle Triassic-Middle Jurassic foreland basin sequences. And then, it is inferred that the collisional orogeny in the Dabieshan orogen took place in the Middle Triassic.

通过对那里沉积物形成环境，特别是物源区的分析研究，识别出震旦系至下三叠统被动陆缘沉积岩系和中三叠统至中侏罗统前陆盆地沉积岩系，据此推测大别造山带碰撞造山作用发生在中三叠世。

Photo Gallery: Jurassic Period The late Jurassic Stegosaurus, like the pair walking through a North American forest in this illustration, was a slow-moving, plant-eating dinosaur that grew as long as 30 feet (9 meters) and as much as 2 tons.

侏罗纪时代图片集。晚侏罗纪古生剑龙，像一双穿过北美森林在这方面的插图，是一个缓慢的移动，恐龙吃植物的增长体长要在30英尺（ 9米）和重达2吨。

The supercontinent of Pangea began to break apart in the Middle Jurassic. In the Late Jurassic the Central Atlantic Ocean was a narrow ocean separating Africa from eastern North America.

盘古大陆在侏罗世中期开始分裂，到了晚侏罗世，中央大西洋已经张裂成一狭窄的海洋，把北美与北美东部分隔开来。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
