Leaving a trail of geological mysteries behind.大地的时候,一个4.5billion岁的星球,还在进化。作为大陆转移和冲突、火山爆发、冰川成长和退去。地壳雕刻

2、在众多和奇妙的方式。只剩下掀翻的奥秘背后地质。2. In this episode, Loch Ness, in the highlands of Scotland， is explored. It holds more water than any other lake in Britain, with a bedrock containing some of the oldest rocks on the planet. Set in a landscape that was once part of America. Loch Ness is a lake with an endurin

3、g myth the Loch Ness monster. A team of scientists investigate how Loch Ness was made. The clues they uncover, also provide a window into the formation of the earth itself.我们将在本集中,尼斯湖水怪,在苏格兰的高地上,进行了探讨。它保存更多的水比其他任何湖在英国,与基岩含一些这个星球上最古老的岩石。设置在一个风景曾是美国的一部分。尼斯湖水怪是一个湖泊,具有不可磨灭的神话尼斯湖水怪。一个科学家小组调查如何尼斯湖水怪。他们揭开的

4、线索,并提供了一扇窗形成的地球本身。3. Deep, dark and full of mystery. This is Loch Ness in the highlands of Scotland. For a thousand years there have been claims that this vast lake hides a strange and terrible secret the fabled Loch Ness monster. A mythical beast, suggested by some as a descendant of the dinosaurs

5、which once roamed this part of Scotland. Loch Ness would be the perfect hiding place for a prehistoric monster. At 23 miles long and a mile wide, this vast freshwater lake covers the same area as New Yorks Manhanttan island. And its more than 700 feet deep. But the monster is not the only mystery th

6、at surrounds Loch Ness. In the hills above the loch, there is a type of rock whose origin baffled scientists for years. Its sandstone. And its the start of the investigation into how Loch Ness was made. 深,黑暗和充满神秘。这是尼斯湖水怪在高地的苏格兰。一千年来一直有声称这种大湖奇怪而可怕的秘密藏着一个传说中的尼斯湖水怪。提出一种神秘的野兽,他被很多人的后裔的恐龙曾经漫步在这一部分苏格兰。尼斯湖

7、水怪,可谓是一个绝佳的隐蔽的地方作为一个史前怪物。23英里长,一英里宽,这巨大的淡水湖覆盖同一区域作为纽约Manhanttan岛。而且它是超过700英尺深。但并不是唯一的神秘怪物围绕尼斯湖水怪。“在小山上方,有一种类型的岩理论的来源困惑科学家多年。这是砂岩。而且它是开始的调查是如何尼斯湖水怪。4. “Its know as the old red sandstone and its given that name because its red and its a sandstone and its called old because its about 350 million years

8、old. ”“这是所知道的旧的红色砂岩、这是考虑到的名字,因为它是红的,而且它是一个砂岩,这就是老,因为它是大约350亿岁了。”5. The old red sandstone runs down one side of Loch Ness. But the most astonishing fact about these rocks is not their age, but where they come from. 旧的红色砂岩跑下去一边的尼斯湖。但最令人吃惊的事实对于这些岩石不是他们的年龄,但是他们来自哪里。6. “These rocks actually belong to my

9、homeland of North America because these rocks originated on the North American continent and then have separated from North America. But in many ways this is almost a little bit of home for me here in Scotland”旧的红色砂岩跑下去一边的尼斯湖。但最令人吃惊的事实对于这些岩石不是他们的年龄,但是他们来自哪里。7. But how do geologists know that this ol

10、d red sandstone comes from 3000 miles away on the other side of the Atlantic Ocean? “These rocks are identical in age and character to the rocks that actually form the Catskill Mountains and so this part of Scotland belonged to northeastern North America”.但是,如何知道这旧的红色,地质学家砂岩来自3000英里远的另一端的大西洋?“这些岩石都是

11、相同的年龄和性格形成的岩石,实际上卡兹启尔山脉,于是这一部分属于北美苏格兰东北部”。8. For more than a thousand years, old red sandstone has been used for building castles in this part of Scotland. But its also been quarried in the US and used for brownstone building in New York City. Under the microscope rocks from both continents have an

12、identical crystal structure and chemical analysis has also proved that theyre exactly the some age. But how did part of America end upon the shores of Loch Ness?一千多年,旧的红色砂岩已被用于建筑城堡的这部分的苏格兰。但它也是被开采出来的在美国和用于上流社会的建筑在纽约市。在显微镜下岩石来自两大洲有一个相同的晶体结构和化学分析也证明了他们是完全一些年龄。但美国的一部分是如何结束的尼斯湖的海岸上9. To answer this cruc

13、ial question the investigation mast go much further back in time to look for evidence in the ancient bedrocks of northern Scotland. Its here that the story of Loch Ness begins. 要回答这个关键性的问题调查桅杆进一步返回到时间里去寻找证据,在古老的中坚北部的苏格兰。这是这里的尼斯湖那故事的开始。10. The trail starts north of Loch Ness, where the bedrock comes

14、to the surface; this landscape is full of the extraordinary mysteries of an unimaginably ancient past. Its made of a type of rock called Lewisian Gneiss. Recent drilling and blasting for a new road cut have exposed evidence which uncovers a amazing chapter in earths history. The long straight lines

15、are the drill holes left in the rock face. Modern radioisotope dating has given geologists the first clue to understanding the origin and formation of these rocks. 审讯的开始,在北的尼斯湖的基岩来到地表,这一景观,充满了非凡的神秘主义的一个常人难以想象的古老的过去。它是由一种称为Lewisian片麻岩的岩石。最近的凿岩爆破为新建公路削减所暴露的证据揭示了一个惊人的一章,在地球史上。它那又长又直的线条是钻孔忘在岩石表面的。现代利用放射

16、性同位素地质学家第一个线索给了理解的起源和形成这些岩石。11. “These rocks are very special to geologists. They are some of the very oldest rocks in the world. We see them in very few places perhaps a dozen places across the globe contain rocks of this age, talking about two and a half to three billion years old”.“这些岩石都是非常特别的地质学

17、家。他们是一些非常古老的岩石,在世界上。我们看到他们在非常少的地方,或许会使得世界各地的12个地方包含岩这个年龄,谈论两个半到3亿岁”。12. The origin of the gray Lewisian Gneiss lies in the first crust that cooled on the surface of the earth. After its formation 4.5 billion years ago, part of this crust were mixed together with the earliest sediments, buried, re-me

18、lted and forced back up again and again for more than a billion years. These extraordinary rocks are the result of that devastating period in our planets history. And theres more evidence exposed in this road cut revealing crucial information about the early history of the Loch Ness region. Lewisian

19、起源的灰色片麻岩在于第一外壳的冷却地球表面的。在其生成45亿年前,其一部分表层沉积物结合在一起,被埋,最早熔不得不退又一个多亿年前。这些不寻常的岩石都是毁灭性的结果,在我们这个星球的历史时期。并且有更多的证据揭示这条路切中暴露出的重要信息的早期历史尼斯湖地区。13. “This exposure contains three important pieces of geological jigsaw puzzle. First, we have the gray gneiss of 2.5 to three billion years old. Secondly, we have this b

20、lack igneous material which has been intruded into the area. This is two billion years old. And thirdly, we have this pink granitic intrusion that both intrudes the black material and the gneiss and this is 1.8 billion years old”这暴露包含三个重要的地质拼图碎片。首先,我们得灰色片麻岩的2.5到3亿岁。其次,我们有这黑色的火成岩的材料,这已经闯入了这一地区。这是两个亿岁

21、。第三,我们有这个粉红色花岗岩侵入,这两个侵犯我国黑的资料和片麻岩和这是1.8亿岁14. This evidence reveals that after the formation of the Lewisian Gneiss, much younger rocks were then melted and mixed into the ancient crust. But this process took an incredible length of time.这证据显示,Lewisian后片麻岩的形成,更年轻的岩石随后被融化,混合成古地壳。但是这个过程起了一个难以置信的时间长度。15

22、. “What weve got here are rocks that record over a billion years of earth history. Now, to put that into perspective that is almost a quarter of the age of the earth recorded in this exposure”“我们拥有什么,这里是岩石记录超过十亿多年的地球的历史。现在,为了把它列入角度说,几乎四分之一的地球年龄的记录在这个曝光”16. This is the bedrock of Loch Ness. It carrie

23、s an extraordinary story of a major part of earths history. And there are yet more secrets hidden in these rocks.这是尼斯湖水怪的基石。它携带一个离奇的故事的地球历史的重要组成部分。还有更多的秘密,隐藏在这些岩石。17. “It looks very much because of the temperatures and pressures that these rocks were under that theyve been to depths of perhaps 50 mi

24、les beneath the earths surface in the past. This suggests that these rocks have been to hell and back two or three occasions over a billion year period”“它看起来非常多,因为的温度和压力下,这些岩石都是:他们已经50英里深处的,也许在地球表面在过去。这表明这些岩石去过地狱和背部有两三次超过十亿年内”18. Geologists now know that the only force powerful enough to produce thi

25、s extraordinary mix of rocks is plate tectonics.地质学家们现在知道的唯一力量的威力足以产生这个离奇的岩石是板块构造的混合。19. Plate tectonics is the process by which the giant plates of the earths crust are driven slowly across the planets surface by vast convection currents deep in the earths hot mantle. In the Loch Ness region, the e

26、vidence in the road cut reveals that incredible pressures forced the crust deep down into the earth where it was melted, deformed, mixed together, then finally brought back to the surface. After that, for another billion years, this ancient land mass quietly eroded down to a rough, rolling landscape

27、. But this wasnt the green terrain we see now. There was much less oxygen in the earths atmosphere than today and the surface would have looked like a lunar landscape, desolate and sterile. Incredibly, remnants of that billion year old landscape are still preserved today. The clues are revealed in a

28、nother road cut, where the trained eye can draw amazing conclusions from what looks like a jumble of rocks.板块构造的过程称为巨大的地壳板块带动慢慢地走过这个行星的表面,深受广大对流在地球深处的热地幔。尼斯湖水怪是存在的地区,在道路的证据显示,令人难以置信的压力迫使削减地壳深入地球它是从哪里融化,丑陋,混合在一起,然后最后带回到了地面。在那之后,对另一个亿年间,这个古陆块的粗略侵蚀下来静静地、轧制景观。但是这并不是我们现在看到绿色的地形。有大量的少量的氧气在地球的大气层比今天和表面可能看起

29、来像一个月亮的景观,荒凉而贫瘠。难以置信的是,余下的那亿岁。今天仍然保存景观解谜的线索展示着另一条路切,那里的训练眼可以画出惊人的结论从看上去像一大堆岩石。20. 21. “At this road cut, we can see Lewisian Gneiss which is between two and a half and three billion years old. But up here we have something completely different. If I go up to this level and look above it, we have hor

30、izontally bedded red sandstones” This sudden change in rock type helps to unravel the mystery hidden in these ancient formation. “在这条路,我们可以看到Lewisian切割片麻岩,介于两个半和3亿岁。但在这里,我们有一些完全不同的东西。我若升到这个水平,仰视天空,我们都有红色砂岩的横向刚性”这种突然的改变在岩石类型有助于揭开最后的谜底,隐藏在这些古老的形成。22. “Theyre believed to have been laid down in a contin

31、ental environment by rivers. Weve got river systems that laid down horizontally bedded sedimentary rocks on ancient landscape”“他们相信已被记载在一个陆地环境的河流。我们已经得到了河流系统的横向埋入沉积岩放下关于古代山水”23. So this simple outcrop reveals that even in a world with little oxygen, the ancient bedrock of Scotland was covered in riv

32、ers a billion years ago. And theres yet another secret hidden here.因此这个简单的露头显示,即使是在一个世界同氧气很少苏格兰,古代的基岩上满是河流亿年前。还有另一个秘密隐藏在这里。24. “There is a junction between these rocks which are almost a billion years old and the rocks below that are two and a half to there billion years old. This is a major time gap of between one and half and two billion years”“有一个这些,岩石交界几乎亿年,下方的岩石,是两个半到那里亿岁。这是一个重要的时间间隔之间的一个半和两个亿年前25. The time gap revealed here is extraordinary. It shows that after the traumas of their early formation, the rocks of the Loch Ness region went through a period of ca
