| 1. | This rock type originates in the magma chambers that underlie volcanoes 这种岩石源自火山底下的岩浆库。 |
| 2. | In caldera , thrusting jets of air rise through fine sand , mimicking the development and collapse of a volcanic magma chamber 的上升气流穿透细沙层喷射而出,模拟岩浆室在火山内的形成与塌陷。 |
| 3. | As the land above the magma chamber collapses , immense gray clouds called pyroclastic flows burst out horizontally all around the caldera 当岩浆库上方的陆地崩陷,称为火山碎屑流的巨大灰色云雾,会突然由火山臼的周围向外水平散开。 |
| 4. | 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。 |
| 5. | When the enormous magma chamber at santorini finally collapsed to form the existing caldera , enormous tsunamis ( tidal waves ) spread outward in all directions 圣多里尼火山的巨大岩浆房最后倒塌,形成了现有的喷火山口,巨大的海啸(潮汐波)向各个方面向外伸展。 |
| 6. | According to temperature , pressure , and chemical evolution of mineral crystallization in the magma chamber , it is held that the magma of intrusive rocks ascended rather fast and was emplaced at the relatively shallow place 据岩浆房中矿物结晶时的温度和压力条件、矿物的结晶特征及演化趋势,推测岩浆上升速度较快,侵位较浅。 |
| 7. | Such old zircons could exist in the youngest ash only if they originated in material that was ejected during the oldest eruptions and if that material later collapsed back into the magma chamber and remelted to help fuel the youngest eruptions 这麽老的锆石能够存在最年轻的火山灰中,除非它们是来自最古老的喷发物质,而且这些物质后来塌陷回岩浆库并再次熔化,以助于点燃最近一次的喷发。 |
| 8. | The geologic , element and experimental study suggest the mechanism of small body , giant deposit in jinchuan is succeeding segregation whole magma chamber intruding from deep to emplace . the study is proof , supplementary and progress of the deep segregation , penetrating ore formation theory , which was advanced by mr tang zhongli , the academician of china . 5 特别是通过铂族元素、稀土元素研究、实验地球化学研究及其与实际资料的对比,提出了金川矿床成岩成矿是从深部到侵位持续熔离的新模式,论证、补充和发展了汤中立院士提出的深部熔离成矿说。 |
