中文摘要
翻译
大陆地壳在深度超过30公里处的温度可以达到800摄氏度以上。在这个温度下,大多数岩石开始融化,使花岗岩变成液体和固体残留物。花岗岩液体密度较小,会上升。因此,地壳上15公里的花岗岩成分比地壳平均值多,下地壳的花岗岩成分比地壳平均值少。地壳就是通过这个过程分化出来的。但残留物的成分告诉我们,花岗岩的形成比到达上层地壳的要多;有些人被困在下层和上层社会之间。
英文摘要
The continental crust can reach temperatures over 800 degrees celsius at depths greater than 30 kilometres. At this temperature most rocks have started to melt, making granite liquid and a solid residue. The granite liquid is less dense and rises. Thus, the upper 15 kilometers of the crust is more granitic in composition, and the lower crust less granitic, than the crustal average. The crust is differentiated by this process. But the composition of the residue, tells us that more granite was made than reached the upper crust; some got stuck between the lower and upper crust.
