1·The volcanics can be divided into three lithofacies: volcanic explosive facies, effusive facies and volcano-sedimentary facies.
火山岩可划分出三个岩相带：火山爆发相、火山溢流相和火山沉积相。
2·Maps of these oil production variables generally showed the same north south trend observed on lithofacies maps.
这些采油量变量图通常呈现在岩相图上观察到的相同的南北走向。
3·And then studied the origin and lithofacies meaning of siderite.
在此基础上研究了菱铁矿的成因和岩相意义。
4·Volcanic lithology and lithofacies are the main factors that control the types and forms of the volcanic apparatus in the Songliao Basin.
火山岩岩性和岩相是控制松辽盆地古火山机构类型及形态的主要因素。
5·Sedimentology plays an important role in the analysis of orogenic stratigraphy and lithofacies, but more attention should be paid to the close relation between sedimentology and tectonics.
沉积学在造山带地层和岩相分析中具巨大作用，应更多强调构造与沉积学的紧密结合。
