2.The Hexi area is located at the tectonic convergence of the north Qilian Caledonian orogen,Alex block and Ordos block where was the transitional period between the early Paleozoic oceanic stage and the Mesozoic continental basin developing stage in the mid-late Paleozoic age. The explanations proposed for the formation mechanism of the mid-late Paleozoic basins are varied.
贺西地区处于北祁连加里东褶皱带、阿拉善地块与鄂尔多斯地块的交汇处,该区晚古生代早中期处于早古生代洋盆体制与中生代陆内盆地发育期的转换时期,其盆地性质及成因争议颇多。
3.Based on discussion on the Paleozoic geodynamic evolution in the western Tianshan Mountains, three mimeralization zones mentioned above are correspondent with the Alataw-Kokirqin Late Paleozoic island arc zone, the Boluokeluo Late Paleozoic back-arc basin and the Awulale Permian rift zone respectively.
通过对西天山古生代的地球动力学演化探讨 ,认为上述 3条成矿带对应的大地构造单元分别为阿拉套—科古琴晚古生代岛弧带、博罗科洛晚古生代弧后盆地和阿吾拉勒二叠纪裂谷带。
4.This region has experienced a geotectonic evolution of at least four stages from Archeozoic continental nucleus,middle Proterozoic-early Paleozoic geosynclinal rift. late Paleozoic platform aulacogen to Mesozoic diwa,and formed four-layer Structure of crystalline basement,fold basement,platform cover and diwa cover.
指出本区地壳经历了从太古代陆核阶段→中元古代—早元古代地槽裂谷阶段→晚古生代地台断拉谷阶段→中生代地洼陆相火山岩阶段的多阶段演化，形成了结晶基底、褶皱基底、地台盖层和地洼盖层的四层结构。
5.The Siberian and Kazakhstanian plates took part in the three developmental stages of the Early Paleozoic Iapetusa, Late Paleozoic Angara and Eurasia since the late Early Permian.
西伯利亚和哈萨克斯坦板块经历了早古生代亚伯特斯古陆、晚古生代安加拉古陆和早二叠世晚期以来欧亚大陆3个发展阶段。
6.Coesite-bearing zircons from the Qinglongshan eclogite in south Sulu yielded Early Paleozoic UHPM ages, 441±9 Ma,449±9 Ma and 442±9 Ma, whereas the core of zircon with plagioclase and apatite inclusion in it gave a protolith age of 761±13 Ma. The age data suggest that the Early Paleozoic UHPM rocks extend from west to east for about 4000 km across the COB and the Triassic UHPM belt extends within the Dabie-Sulu region for about 1000 km.
获得江苏东海县青龙山榴辉岩含柯石英等超高压矿物锆石的年龄为441±9 Ma,449±9 Ma,和442±9Ma,平均444±9 Ma,核部含斜长石+磷灰石锆石年龄为761±13 Ma,认为前者代表超高压变质年龄,后者代表榴辉岩原岩结晶年龄。
7.Chengdao Oilfield is the first equipped oil field found at shallow sea in the east of China, in which eight oil-bearing formations were found such as Archean group, lower Paleozoic, upper Paleozoic, Mesozoic group, Paleogene Shahejie group, Dongying group, Neogene Guantao group, and Minghuazhen group, showing a typical compound accumulation area of oil and gas.
埕岛油田是在我国东部浅海海域发现的第一个整装油气田 ,已发现了太古界、下古生界、上古生界、中生界、古近系沙河街组、东营组、新近系馆陶组、明化镇组等八套含油气层系 ,为一典型的复式油气聚集区。
8.According to the study on the ore forming times of 1085 major copper deposits,the copper deposits in China have been divided into six metallogenic periods of Precambrian,Early Paleozoic,Late Paleozoic,Trias,Jurassic-Cretaceous and Cenozoic Era.
根据全国1085个主要铜矿床的成矿时代研究,将中国铜矿床划分为前寒武纪、早古生代、晚古生代、三叠纪、侏罗-白垩纪、新生代六个成矿期。
9.We suggested that all the Early Paleozoic poles for NCB were placed in the Atlantic, and the NCB located in the southern hemisphere at about 15 degrees in the Early Paleozoic.
与此相应，华北地块位于南纬15°左右．
10.Santanghu Basin is located between Altai Mountain and Tianshan Belt,it is a composite and reconstructed basin which superposes on the Paleozoic erogenic belt of Paleozoic age.
