crustal

As geologic forces pulled the crustal plate apart, new volcanoes formed in parts of the rift.

当地质作用力（试图）把地壳版块分开，版块开裂的一些地方就会形成新的火山。

The study authors propose another, more radical, explanation: The crustal rock they analyzed, called ferroan anorthosite, is not linked to magma dynamics at all.

这项研究的作者提出了一个更大胆的解释：他们分析了这种被称为铁斜长岩的月球地壳岩石，发现其并不与岩浆的运动相联系。

Iceland is geology in action. A one-hour flight from Reykjavik skims over steaming geothermal areas, the great crustal rift and some of the country's most famous volcanoes.

冰岛的国土一直处于地质活跃中。从雷克雅未克乘飞机飞行一个小时，途中尽是冒着蒸汽的地热区、巨大的地壳裂缝以及岛国最著名的几座火山。
