| 1. | The pilot study on arctic mid - ocean ridge - introduction of amroe 2001
北冰洋gakkel洋中脊科学考察的初步认识- amore 2001简介 |
| 2. | Seamounts , underwater volcanoes , rift valley , the mid - ocean ridge , constitute a rich world of the ocean floor
海底山脉、海底火山、裂谷、大洋中脊等等，构成了丰富的海底世界。 |
| 3. | Characteristics of trace and rare earth elements suggest that ophiolite originated from the setting similar to mid - ocean ridge
微量元素和稀土元素特征显示蛇绿岩形成于类似洋中脊的构造环境。 |
| 4. | The film follows a team of scientists as they dive to research mysterious hydrothermal vents on the mid - ocean ridge of atlantic ocean
观众将会跟随科学家深入大西洋中洋脊，研究该处奇特的热喷口。 |
| 5. | Jurassic and cretaceous , the marginal ocean basin was in the stage of ocean crust evolution and had a setting similar to mid - ocean ridge
侏罗白垩纪为洋盆洋壳演化期，处于类似洋中脊的构造环境。 |
| 6. | Since the size of the earth is essentially constant , new lithosphere can be created at the mid - ocean ridges only if an equal amount of lithospheric material is consumed elsewhere
因为地球的大小本质上是不变的，只有同等数量的岩石圈物质在其它地方被吞没，新的岩石圈才能生成。 |
| 7. | Two ree distributed pattern , lree - depleted and flat , which display a specific character of typical mid - ocean ridge tholeiite , indicate that primary magma may be derived from near primary or a typical large ion lithophile element ( lile ) - depleted mantle
岩石稀土元素配分模式可分为lree平坦型和lree亏损型两类，指示了其原始岩浆起源于近原始或典型的大离子元素亏损型的地幔，为典型的大洋中脊拉斑玄武岩的特征。 |
| 8. | It also implied that mother magma formed mafite was a residual melt trace elements distributed pattern is similar to transitional mid - ocean ridge basalt simultaneously , the pattern , which displayed a clear ( k ) . rb . ba , th , ( th ) - enriched , also can be explained as an ocean ridge environment overlappe d with mantle plume
其微量元素的分配形式类似于过渡类型的洋中脊玄武岩，同时表现出( k ) 、 rb 、 ba 、 th 、 ( ta )的明显富集，也可解释为在洋中脊环境上叠加了地幔柱的特征。 |
| 9. | Through the systematic analysis and contrast studies on topographical environment characteristics of these typical regions , it is found that the hydrothermal activity only occurs under the circumstance of the particular topographical environment , though it distributes widely in the tensional tectonic environment , for instance , the mid - ocean ridges , transform faults zones , back - arc spreading basins and the modern marine craters regions
通过对典型热液区地形环境特征的系统分析和对比研究发现尽管现代海底热液活动广泛分布在大洋中脊、转换断层、弧后扩张盆地等各种不同的张性构造环境及现代海底火山活动区，但也仅出现在特殊的地形环境条件下。 |
| 10. | Students of the earth ' s mid - ocean ridge were closely following the incoming data from the galileo mission to jupiter , looking for more hints that an ocean of water - and with it , undersea volcanoes - could exist under the ice that covers jupiter ' s moon europa future interlanetary missions to europa and other promising sites seemed far more likely to find support than they had before mckay ' s announcement
研究地球大洋洋底形成的海脊的学者也在密切注视探索木星的伽利略号飞船传回的最新信息：在木星的卫星欧罗巴表面冰盖下面是否存在着海洋及海底火山的迹象，将来飞往欧罗巴及其他可能有生命的地点的星际航行任务可能会带来更多的新发现，支持地外生命这一假设。 |
