The optimization function of faults on forming of igneous reservoirs is specially pointed out.(特别指出了该区断层对火成岩油气藏的形成所起的优化作用。)
The rocks here are igneous and do not fracture along predictable lines.(这儿的石头都是火成岩，石头的裂缝极不规则。)
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。)
I wonder if there are further classifications of igneous rocks.(我想知道火成岩还有进一步的类型划分吗。)
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。)
Such meteorites look like igneous rocks from earth-hence the belief that Vesta has a mantle.(这种陨石与地球上的火成岩相似—因此可以相信灶神星上有地幔存在。)
Its compounds are found in practically all igneous rocks and their sand deposits.(几乎在所有的火成岩及其沙尘堆积物中都可找到其混合物。)
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。)
The Yogo dike is a narrow subvertical sheet-like igneous body.(Yogo堤防是一个狭窄的亚垂直片状火成体。)
Texture and structure of igneous rocks and classification.(岩浆岩的结构和构造岩浆岩的分类。)
