古生代的

It seems that Palaeozoic tiny Chondrites can be formed in shallowest and middle tierings.

指出Chondrites的阶层分布和对古氧相的示踪在古生代与中生代有重要差别。

The Palaeozoic complexes on the northern margin of the Ergun block may be regarded as the main provenance of the basin.

盆地南侧的额尔古纳地块北缘古生代杂岩可能是盆地的主要物源。

The confirmation of OIB suggests that Altun area existed paleo-oceanic basin in early Paleozoic, which therefore supports the existence of Hongliugou ophiolite and also implying a mantle plume activity at that time.

OIB的确定说明早古生代初，区内存在古洋盆，从另一个侧面证实红柳沟蛇绿岩的存在，也暗示当时就可能出现地幔热柱活动印记。

The Centr al Tethys Region lies in Hoh Xil-Bayan Har. Since Late Palaeozoic, the back-ar c bathyal basin continued to break and spread. The typical oceanic crust was event ually formed in Carboniferous and Permian. The Ocean during that period is named the Paleo-Tethys, of which the remnant is the Third and the Fourth suture zone s.

特提斯中区位于可可西里—巴颜喀喇，古生代晚期以来在弧后盆地基础上继续破裂、扩张，典型的洋壳形成于石炭—二叠纪，这个时期的洋称古特提斯，它的遗迹为第三和第四缝合带。

In the late Eopaleozoic period, large-scale concourse movement took place in Palaeo-Asian Ocean, and the combined Kazakhstan Plate was formed. Junggar Basin has become a part of this plate and entered the inter-plate cratonization evolutionary phase.

早古生代后期，古亚洲洋发生了大规模的汇聚运动，哈萨克斯坦联合板块形成，准噶尔成为其一部分，进入板内克拉通化演化阶段。

Geochemical analysis results of the basalts indicate that they were formed within oceanic plate.

玄武岩样品的地球化学分析结果表明，它们形成大洋板内构造背景，这证实了对古特提斯东延的设想，并有必要重新认识广西晚古生代地质演化的历史

In the Paleozoic era,the northern border area of North China Craton belonged to the tectonic domain of south peri-Paleozoic ocean and is characterized by subduction-collision orogenesis,leading to the formation of EW- to ENE-trending folds,thrust faults,nappes and ductile shear zones etc.

古生代，华北地块北缘处于古亚洲洋构造域，造山作用属陆缘俯冲-碰撞型，形成以EW向至NEE向为主的褶皱、逆冲推覆构造及韧性剪切带等构造类型。

In the convergent processes of Pangia in Late Paleozoic, Tarim massif, Kazakhstan-Yili plate, Siberia plate, North China plate all amalgamated in Paleo-Asiatic tectonic domain.

在晚古生代Pangia的聚合过程中，塔里木地块和哈萨克斯坦-伊犁板块、西伯利亚板块、华北板块等在古亚洲构造域的造山过程中拼合在一起。

Tectonic analysis of Pre-Carboniferous metamorphic stratum and structural foliation dating have shown that The Qinling and its vicinities had happened an important regional tectonic event -Caledonian event, this event represents early paleozoic closure of the Qinling ocean basin and continent-continent obliquely diachronous collision, so we also could reconstruct Caledonian Qinling orogenic belt's basic tectonic framework.

对北秦岭地区前石炭纪变沉积—火山岩地层系统进行构造解析，以及构造面理定年数据表明，秦岭及邻区志留纪至早泥盆世经历了区域性的重大构造事件，相当于加里东事件，该事件代表了秦岭早古生代洋盆闭合、陆—陆碰撞造山的造山事件，并可恢复加里东古造山带的基本构造格局。

In Chinese Palaeozoic era, many multiorigin prototype basins were overlapped and composite, paleokarst was welldeveloped because of multiperiod tectonic movement, largethickness and widely distributed carbonate rocks of sea facies.

中国古生代具有多时代、多类型原型盆地叠加复合的特点，海相碳酸盐岩分布广、厚度大，受多期构造运动等因素的控制和影响，古岩溶十分发育。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
