玄武岩

The original alkalic series of basalic magma evolutes into trachybasalt through crystallization differentiation of olivine and pyroxene, and the trachybasalt is transformed into alkalic rhyolite with remarkable Eu, Sr, Ba, Ti, P nagetive abnormalities through strong crystallization differentiation of plagioclase and also pyroxene Ti Fe oxides and apatite, all together leading to the loss of neutral (SiO 2=57%～63%) andesite and trachyandesite in the volcanic rocks in this area and appearance of bimodal volcanic rock combination feature.

原始碱性系列玄武质岩浆经橄榄石、辉石的结晶分异，向粗面玄武岩演化；粗面玄武岩经斜长石强烈的结晶分离作用，还有辉石、钛铁氧化物和磷灰石的分离结晶作用形成具显著Eu、Sr、Ba、Ti、P负异常的碱性流纹岩，导致本区火山岩缺失中性(SiO2=57%～63%)的安山岩和粗安岩，呈现双峰式火山岩组合的特点。

The activities of Wangtian′e volcano lasted for three periods:①The Changbai period volcanic rocks consisting mainly of trachybasalt with small amount of alkalic basalt and basaltic trachyandesite;② The Wangtian′e period can be further divided into early and late periods, the early period volcanic rocks consisting of basaltic trachyandesite and trachyte, the late period volcanic rocks cosisting of alkalic rhyolite;③The Hongtoushan period volcanic rocks consisting of alkalic rhyolite.

望天鹅火山活动从早到晚分为三期：①长白期以粗面玄武岩为主，少量碱性玄武岩和玄武质粗安岩；②望天鹅期又分早晚两个亚期，早期玄武质粗安岩和粗面岩，晚期碱性流纹岩；③红头山期碱性流纹岩。

Trachyte has as the same isotope feature as the basalts, indicating that they were derived from the same source, and resulted from products during different evolution phases of the same magma source, which is similar to that of the basalts in Emeishan.

该区粗面岩类与玄武岩的同位素特征类似，说明二者具有相同的源区，并可能代表了同源岩浆不同演化阶段的的产物，这与峨眉山地幔柱岩浆活动的玄武岩与粗面岩所具有的演化关系相同。

The basalt lava, the tiger xipi, the fierce appearance red, the fierce appearance white, G648, Zhangpu Huang Xiushi, Zhangpu black (the Asian refacing, litchi pan, board blackened by fire, sand blasting board, longan fur plates, chip axe surface, machine cut hair side, pineapple surface and so on), the pearl black, also have thick pore basalt, black hole stone, slate sandstone and each kind of size type modelling stone carving, the arc, the different shape processing, Lu Yanshi, each kind of processing surface place Guangdong Shi Zhuan, asked knows Shi Jidou the stone, granular and the striation blind grain stone, the mushroom stone, the landscape stone, the article fossil, the natural build botanical garden stone and so on.

玄武岩火山石、虎皮黄、虎皮红、虎皮白、G648、漳浦黄锈石、漳浦黑（亚光面、荔板面、火烧板、喷砂板、龙眼皮板、剁斧面、机斩毛面、菠萝面等）、珍珠黑、还有粗细孔玄武岩、黑洞石、板岩砂岩及各种大小种类造型的石雕刻、弧形板、异形加工、路沿石、各种处理面的地埔石砖、问知石及斗石、粒状和线状盲纹石、蘑菇石、景观石、文化石、自然体形园林石等。

The Cenozoic basalts in mainland of eastern China are the products of multiple extrusion.

本文以中国东部6个地区的新生代大陆玄武岩及其幔源包体为研究对象，测试和搜集了玄武岩的常量元素、微量元素和单斜辉石斑晶的化学成分及Sr、Nd同位素资料以及幔源包体的常量元素、微量元素和矿物化学成分。

Moreover, in some favorable places where basalts are intersected by granites, the NO.

值得重视的是，区内火山沉积型Cu矿床在空间上与玄武岩的密切依存关系可用于指导找矿，而且在玄武岩受花岗岩交切的某些有利部位可找到403〓矿体式和双竹式Sn、Cu矿床。

In order to understand the genesis of the copper mineralization in the Emeishan basalts, the authors studied characteristics of Cu, PGE and other trace elements in copper ores from the basalts in the Yunnan-Guizhou border area.

为了进一步探讨玄武岩铜矿的成因，文章对滇黔交界地区玄武岩铜矿石的铜、铂族元素及其他微量元素的地球化学特征进行了研究。

The volcanic rocks are dominated by basalts, diabases, andesite-basalts and with minor dacites and rhyolites, which are fallen into sub-alkaline series.

研究区内火山岩主要岩石类型为玄武岩、安山玄武岩、辉绿岩、安山岩以及少量英安岩和流纹岩。

The feasibility of using mode converted waves (P to S and vice-versa at the top and bottom basalt interfaces) for sub-basalt imaging in Kutch region is discussed through a series of velocity-depth profiles.

通过一系列速度-深度剖面探讨了利用模式转换波(顶底玄武岩界面上的P波转化为S波或相反)对印度库奇地区玄武岩下成像的可行性。

All of the above characteristics as well as poorcrystallized, abundant peridotite inclusions, few xenocrysts, and elements covariation trend indicate that the Tianheyong basalts were solidified from primitive basaltic magma.

上述所有特征以及岩石结晶程度低、富含橄榄岩包体和少量捕虏晶、元素变异关系等均表明，天和永玄武岩是原生玄武岩质岩浆固结的产物。

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。
