| 1. | The continental crust is much thicker than average beneath the great mountain belts . 在高山地带下面的大陆地壳,其厚度要比平均厚度大得多。 |
| 2. | The convective heat of molten magma in the upper 10 km of the continental crust represents a significant geothermal energy resource 大陆地壳10公里深度以内熔岩中的对流热是一种重要的地热能资源。 |
| 3. | " but at the same time , a horizontal pulling power inside the lower continental crust and mantle of the earth counteracts this upward movement , " said bian “但同时,从下地壳一直到地幔上部在产生一种东西拉张的力量,这种拉力对喜马拉雅山的继续升高起到了阻碍作用。 ” |
| 4. | " but at the same time , a horizontal pulling power inside the lower continental crust and mantle of the earth counteracts this upward movement , " said bian “但同时,从下地壳一直到地幔上部在产生一种东西拉张的力量,这种拉力对喜马拉雅山的继续升高起到了阻碍作用。 ” |
| 5. | Networks of satellites already on orbit or soon to be launched are beginning to provide detailed observations of the workings of the atmosphere , ocean , and continental crust over the entire planet 由已经进入轨道或是即将发射的卫星所形成的网络已开始提供有关整个地球的大气、海洋和陆壳运动情况的详细观测资料。 |
| 6. | A large number of studies of geochronology and geochemistry indicate that mesozoic intermediate - felsic rocks from the dabie orogen have originated from recycling of the subducted yangtze continental crust itself 摘要大量的同位素地质年代学和地球化学研究表明,大别山中生代中酸性岩为俯冲扬子陆壳再循环的产物。 |
| 7. | The independent jiangda tectonic belt has appeared since late carboniferous , following the jinshajiang ocean crust of subducted beneath the changdu continental crust and the continental margin arc formed in east of changdu terrane 自晚石炭世金沙江洋洋壳开始向昌都陆壳地体边缘下俯冲,形成陆缘弧以来,独立的江达构造带就得以产生。 |
| 8. | During the magma evol ution , this primary magma suffered effects of the containing water fluid and a small extent contaminate of continental crust . according to all of features above , the paper analyzes the formatting mechanism of high - mg volcanic rocks 岩浆演化过程中遭受到了含水流体的影响及轻微的陆壳混染。根据以上特征对高镁火山岩的形成机制作了分析。 |
| 9. | 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。 |
| 10. | X4 ? gridding attenuation and 2 ? x2 ? gridding group velocity are calculated respectively , based on the attenuation and velocity , the distribuation of rayleigh wave quality factor qr are yielded finally . ( 3 ) building the s - wave quality factor og3d structure of the continental crust and upper mantle of china area 为此把中国大陆区域划分成4 4网格和2 2网格,利用lsqr方法分别进行衰减系数和群速度网格化反演,得到4 4单元格的衰减系数分布和2 2单元网格的群速度分布。 |
