Igneous and metamorphic rocks are more compact, commonly crystalline, and rarely contain spaces between grains.
火成岩和变质岩比较致密，通常是结晶性的，颗粒之间很少有空隙。
Some very ancient sediments were no longer recognizable, having been converted to igneous and metamorphic rocks in the course of mountain building.
在造山的过程中，一些非常古老的沉积物已被转化为火成岩和变质岩，已经无法辨认了。
However, even igneous and metamorphic rocks may act as groundwater reservoirs if extensive fracturing occurs in such rocks and if the fracture system is interconnected.
然而，如果火成岩和变质岩中发生大规模的断裂，并且断裂系统相互连通，那么它们也可以作为地下水储集层。
