| 1. | The evolutionary process in the late triassic period of ordos basin was complex 鄂尔多斯盆地晚三叠世经历了复杂的演化过程。 |
| 2. | Pterosaurs lived in the triassic period with the oldest examples dating back to around 220 million years ago 翼龙生活在三叠纪,而最早的化石样本可以追溯到大约2亿2千万年前。 |
| 3. | The creatures that we normally think of as dinosaurs lived from late in the triassic period ( about 225 million years ago ) until the end of the mesozoic era ( about 65 million years ago ) 这类被称作恐龙的生物生活在从三叠纪(大约2 . 25亿年前)到中生代的末期(大约6500万年前) 。 |
| 4. | Starting from the cambrian period ( 530 mya ) and ending at the early triassic period ( 248 mya ) , walking with monsters shows the life and death struggles prehistoric creatures before the dinosaurs went through 本片介绍了在这段时期内的各种史前生物的生死搏斗,同时也描绘了我们人类最早祖先的真实模样。 |
| 5. | Six geological formations in the parks contain fossils of a wide range of ancestors of mammals , dinosaurs and plants revealing the evolution of vertebrates and the nature of palaeo - environments in the triassic period 公园含有六个不同的地质层,化石囊括了哺乳动物祖先、恐龙、到植物等广阔物种,反映了脊椎动物的进化过程以及三叠纪时期的地球古环境。 |
| 6. | These two contiguous parks , extending over 275 , 300 ha in the desert region on the western border of the sierra pampeanas of central argentina , contain the most complete continental fossil record known from the triassic period ( 245 - 208 million years ago ) 这两个相邻的公园,坐落在阿根廷中部的沙漠地区,总共占地275 , 300公顷,保存有三叠纪( 2亿4千5百万到2亿零8百万年前)最为完整的大陆化石记录。 |
| 7. | Four tectonic evolution phases have been made out in this area . they are original crust formed in the archean - early proterozoic era , continental crust shearing in the middle - new proterozoic era , plate tectonic developed in sinian - triassic period and intracontinental orogeny in the middle cenozoic period 将区内构造演化归纳为太古?早元古代原始地壳形成、中新元古代大陆地壳裂解、震旦?三叠纪板块构造体制、中新生代陆内造山等四个演化阶段。 |
| 8. | In the area of the left bank , rock body is mainly composed of permian period - triassic period granite and triassic period siltstones and mudstones ( t2m ) . moreover , the rock body has been more faulted , such as f1 f3 f9 and so on . in addition , there also exist a lot of joints and form complex rock mass structure 工程区主要出露二迭纪三迭纪花岗岩体( _ 4 ~ 3 _ 5 ~ 1 )和三迭系中统忙怀组下段沉积岩( t _ ( 2m ) ~ 1 ) ,发育有工程区规模最大的f _ 1和f _ 3断层,以及其它断层和大量的各类断续延伸的裂隙,岩体结构较为复杂。 |
| 9. | Because of the above mentioned reasons , the first one should be considered the main source rock in yili basin . by means of the modeling of the buried history and the history of thermal evolution , it can be concluded that this set of source rock had entered the ceiling of the oil - generating window in the early triassic period and reached its peek in the middle and end of triassic period , befor entering the highest maturity in the early and middle jurassic period , and had generating gas in the end of jurassic period 其中铁木里克组烃源岩厚度大、有机质丰度高、成熟度高,具有较高的生烃潜力,是伊犁盆地主要的烃源岩系,通过埋藏史及热演化史模拟,该套烃源岩于三叠纪早期已进入生烃门限,中晚三叠世达到生、排烃高峰,早中侏罗世进入高成熟阶段,侏罗纪末进入生气阶段。 |
| 10. | This text utilizes the sedimentation and petroleum geology theories , makes use of outcrop , well drilling and analysis datum , studies deeply sedimentary facies and microfacies in chang - 6 to chang - 8 oil - bearing layers of triassic period at longdong region in e ' erduois basin . the sedimentary facies include three type : alluvial fan , lake delta , lake and their corresponding parfacies and microfacies . the spreading of the delta has been detailed researched 本文运用沉积学、石油地质学理论,充分利用露头、钻井和测试分析资料,对鄂尔多斯盆地陇东地区三叠系延长组长_ 6 ?长_ 8层位的沉积相、微相进行了深入研究,划分出冲积扇,河流、河湖三角洲、湖泊四种相及其对应的亚相、微相;并对研究区三角洲的展布进行了详细研究。 |
