| 1. | At the same time, we hoped to learn about processes of volcanism that have rarely been observed before .
同时我们希望弄清过去很少能观察到的火山作用过程。 |
| 2. | Bimodal rift volcanism
双向裂谷火山活动 |
| 3. | For a long time researchers believed that etna ' s position at the crossroads of these faults was the explanation for its volcanism
长久以来，研究人员相信埃特纳火山活动的原因，正是因为它位处这些断层的交会处。 |
| 4. | Because the moon has experienced impact , volcanism and tectonic activity , it can serve as a touchstone for understanding those processes
由于月亮经历撞击、火山活动和板块运动，它可以做为了解这些作用的开门砖。 |
| 5. | Massive volcanism , on the other hand , continues to release its pollutants over millions of years , drawing out its effects on life and its habitats
而大规模的火山活动会持续喷出污染物，长达几百万年，对生物与栖所的影响是漫长的。 |
| 6. | Such findings would imply that a new cycle of volcanism had commenced ? and that the newly engorged magma chamber had more potential to explode catastrophically
这样的发现表示新一波的火山作用已经开始，而重新填满的岩浆库，更有可能造成灾难性的爆发。 |
| 7. | The increasing volcanism implies that the regional tectonism became progressively severe from the early stage to late stage of the late carboniferous
自晚石炭世早期到晚期，火山活动期逐渐增长，休眠期逐渐缩短，反映出盆地性质自稳定向活动的转化过程。 |
| 8. | Both kinds of plate boundary are associated with fault systems , earthquakes and volcanism , but the kinds of geologic activity observed at the two boundaries are quite different
两种板块边界均与地层系统、地震以及火山活动有关，但在两种边界处观察到的诸般地质活动却迥然不同。 |
| 9. | The iridium layer commonly used to support catastrophism fits into this theory as evidence for the extreme volcanism that would have been produced by the eruption of larasia and gondwana
至于那个支持灾变说的铱异常层，则可能是拉拉西亚和冈纳德万喷发时特别强大的火山作用的产物。 |
| 10. | This hypothesis gained strength when we learned that the ages of the zircons from post - lava creek eruptions span the entire two - million - year duration of yellowstone volcanism
我们得知克里克熔岩喷发物质中的锆石，年龄分布横跨整个黄石火山现象的200万年，这使我们的猜测更有说服力。 |
