吉林省蛟河市境内大石河新生代玄武岩中含有丰富的地幔橄榄岩包体，详细的岩石学与矿物学研究显示，这些包体的主要岩石类型为尖晶石二辉橄榄岩-方辉橄榄岩，未发现石榴石橄榄岩。

It is inferred that the Cretaceous rhyolitic rocks developed widely in Zhejiang Province probably originated by partial melting of the basement metamorphic rocks. Continuous underplating of basalt resulted in significant increase of introduced mantle-derived materials with time.

推测浙江省广泛发育的白垩纪流纹质火山岩可能是基底变质岩部分熔融形成，由于持续的玄武岩底侵作用，造成幔源物质的加入量显著地随时间增加。

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

Geological and geochemical characteristics of the Early Ordovician volcanic rocks from North Qilian Mountain show that they are of the basalt-andesite association with no acid rocks or volcanic rocks of the shoshonite series.

早奥陶世阴沟群火山岩的地质－地球化学特征的研究结果表明，该期火山岩的岩石组合为玄武岩－安山岩组合，缺乏酸性火山岩和橄榄玄粗岩系列火山岩。

On Skye's Trotternish Peninsula, basalt pinnacles loom over the Sound of Raasay.

在斯凯岛的托尼特尼半岛，玄武岩尖塔笼罩的拉赛的声音。

In this paper, we firstly introduced the theory of the FORC diagram and its physical explanations. We then applied the method in detecting the thermal alteration of a basalt sample, which contains aluminum-substituted titanomagnetite.

本文首先详细介绍该方法的基本原理和其物理意义，在此基础上，给出了一个应用FORC图确定含铝的钛磁铁矿玄武岩样品中磁性矿物在加热过程发生转变的研究实例。

Diaojiaohaizi is a thoroughly closed basaltic depression lake on the top of Daqing mountains which has many advantages when it is used in studding vegetational evolution and climatic changes of the Holocene.

调角海子为大青山顶部的一个全封闭的玄武岩洼地湖泊，冰后期积水成湖，其湖泊沉积物具有用来研究全新世植被和气候变化的许多独特优点。

The tools are known as cobbles, lumps of volcanic basalt split by hitting them with another rock, leaving sharp cutting edges

这些名为砾石的石器，是用另一块石头从火山玄武岩上敲下来的，具有锋利的刃。

The chemical and isotopic arrays formed by basalts indicate mixing of components from two distinct source regions.

玄武岩所形成的化学和同位素阵列表明，它们是由来源于2个不同源区的组分混合产生的。

Geochemical analysis results of the basalts indicate that they were formed within oceanic plate.

玄武岩样品的地球化学分析结果表明，它们形成大洋板内构造背景，这证实了对古特提斯东延的设想，并有必要重新认识广西晚古生代地质演化的历史

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
