1. | A ratio change by as little as0.1 part per million could signal an influx of carbon dioxide from magma |
| 比例的变化即使只有千万分之一,都可能是种警讯,表示有岩浆在火山内累积或逐渐上升,其中的二氧化碳逸出所致。 |

4. | The voluminous alkaline granites in the region were probably from the same magma source, but crystallized |
| 该地区体积巨大的碱性花岗岩可能也来自相同的岩浆源,只不过它是在较浅的地壳深度上结晶的. |

5. | The magma originated from the upper mantle and belongs to the tholeiitic series which has undergone immiscible |
| 岩浆起源于上地幔,属于拉斑玄武岩系列,发生过金属硫化物的熔离作用。 |

8. | a form of igneous rock consisting of extremely coarse granite resulting from the crystallization of magma |
| 一种火成岩,由富含稀有元素的岩浆结晶而成的极粗的花岗岩构成。 |

9. | But,of course,it could also be expelled from the magma itself as it cooled. |
| 不过 当然 也可能是 岩浆冷却后形成的 |
|
|
| |
10. | cannot be certain, however, whether this upsurge is caused by tectonic forces or by a fresh batch of magma |
| 然而,研究人员并不能确定,这样的现象是因地壳运动还是一股从地函上升的新岩浆所造成的。 |
