玄武岩

Petrochemical and mineralogical characteristics of fresh basalt and its saprolite from Touzhai landslide in Zhaotong, Yunnan Province, are described in terms of chemical analyses, optical observations of thin sections and SEM observations.

利用化学全分析、薄片鉴定及扫描电镜等测试、观察手段，分析了头寨滑坡发生的岩体玄武岩及其腐岩玄武岩腐岩的岩石化学和矿物学特征。

Mineralized materials can be leached out from them by supergene water.and each types of ore deposits will be formed at different palaeogeography circumstances.

把玄武岩划分为三个主要的喷发旋回，编制了各个喷发旋回的岩相古地理图，表明不同时期玄武岩的形成环境不同并有着不同的分布范围。

The compositions of major elements from the rocks are consistent with those of basalt and have evolutional current of tholeiite.

岩石的主量元素组成和玄武岩一致，并且具有拉斑玄武岩演化趋势。

Basic suite consists of tholeiite and alkali-basalt.

基性岩套由拉斑玄武岩-碱性玄武岩组成。

The second faulting activity during late period of early Cretaceous, controls the formation of a series of faulting bounded basins with dustpan shape, as well as the formation of interlayer between tholeiite and alkaline basalt bearing olivine existed in red layer.

早白垩世晚期的第二次断陷，则控制了赣杭带沿线—系列箕状断陷盆地以及红层中拉斑玄武岩和碱性橄榄玄武岩夹层的形成。

Metabasic volcanic rocks are a transitional type between island-arc tholeiite and mid-oceanic tholeiite.

而变质基性火山岩属于岛弧拉斑玄武岩与大洋拉斑玄武岩的过渡类型，它们形成于拉张盆地。

The Mg-rich volcanic rocks consist of high-Mg decite and high-Mg basalt which are the products of congenetic magma,in Ashele are, Xinjiang. In comparison with tholeiite, their εNd are obviously low, implying that they are contaminated by the oceanic sediments during their forming process.

阿舍勒富镁火山岩由高镁英安和高镁玄武岩组成它们可能是同源岩浆的产物，与共生的拉斑玄武岩相比，富镁火山岩钕同位素明显富集，反映在其形成过程中受到了大洋沉积物的混染。

Volcanic rocks of Xishanbulake Formation and Shuiquan Formation are of alkali basalt series, those of Zhamoketi Formation are of alkali basalt series and tholeiite series, and those of Beiyixi Formation are obviously characterized by bimodal assemblage and mostly belong to alkali volcanic rocks.

其中，西山布拉克组和水泉组火山岩均碱性玄武岩系列；扎摩克提组火山岩分属碱性火山武岩系列和拉斑玄武岩系列；贝义西组火山岩具有明显的双峰式组合特徵，大部分属碱性火山岩。

The basalt is belong island arc tholeiite and series of the calc-alkaline,and have character of island arc in rare earth element and trace element.

玄武岩属岛弧拉斑玄武岩和钙碱性系列，属太平洋型钠质类型，稀土、微量元素显示具岛弧特征，大地构造位置为岛弧中心靠近大洋一侧，与南侧那拉提晚泥盆—早石炭世侵入岩共同组成火山弧，同为古亚洲洋向北俯冲的产物。

Basalts plot in tholeiite in A.I-Al〓O〓 diagram. They have enriched LREE patterns without negative Eu anomaly. Their Zr/Y=4.4～6.5,〓=0.70790～0.70146, Th＞＞Ta,εNd values are between -1.8 and +3.7, indicating continental contamination. Pb isotope characteristics are close to that of typical tholeiitic flood basalt in the world.

Al〓O〓图上落入拉斑玄武岩区；稀土配分为LREE富集型，均无负Eu异常，Zr/Y＝4.4-6.5，〓＝0.70790～0.70146；Th＞＞Ta，ε〓介于-1.80～+3.7之间，都显示了陆壳混染的影响，Pb同位素与世界上典型拉斑质溢流玄武岩比较接近。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
