The optimization function of faults on forming of igneous reservoirs is specially pointed out.(特別指出了該區斷層對火成巖油氣藏的形成所起的優化作用。)

The rocks here are igneous and do not fracture along predictable lines.(這兒的石頭都是火成巖，石頭的裂縫極不規則。)

Some very ancient sediments were no longer recognizable, having been converted to igneous and metamorphic rocks in the course of mountain building.(在造山的過程中，一些非常古老的沉積物已被轉化為火成巖和變質巖，已經無法辨認了。)

I wonder if there are further classifications of igneous rocks.(我想知道火成巖還有進一步的類型劃分嗎。)

Igneous and metamorphic rocks are more compact, commonly crystalline, and rarely contain spaces between grains.(火成巖和變質巖比較致密，通常是結晶性的，顆粒之間很少有空隙。)

Such meteorites look like igneous rocks from earth-hence the belief that Vesta has a mantle.(這種隕石與地球上的火成巖相似—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.(幾乎在所有的火成巖及其沙塵堆積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，如果火成巖和變質巖中發生大規模的斷裂，并且斷裂系統相互連通，那么它們也可以作為地下水儲集層。)

The Yogo dike is a narrow subvertical sheet-like igneous body.(Yogo堤防是一個狹窄的亞垂直片狀火成體。)

Texture and structure of igneous rocks and classification.(巖漿巖的結構和構造巖漿巖的分類。)
