玄武岩的

Actinolite and pyroxene phenocrysts separated respectively, from chlorite-actinolite schist and altered pillow basalt in the E'rou area of the eastern part of the Shuanghu-Longmuco suture zone, yield well-defined 40Ar/39Ar plateau ages of 235.9±2.6 Ma and 232.5±2.4 Ma. These nearly identical ages are interpreted as defining the age of the tectonothermal event of subduction-related collision along the Shuanghu-Longmuco suture zone.

在藏北龙木错－双湖缝合带东段双湖鄂柔地区，获得绿泥阳起石片岩中阳起石矿物的40Ar/39Ar坪年龄为(235.9±2.6)Ma和枕状玄武岩中蚀变辉石斑晶的40Ar/39Ar坪年龄为(232.5±2.4)Ma，两个年龄具有极好的一致性，记录了中三叠世晚期－晚三叠世早期沿龙木错－双湖缝合带发生俯冲碰撞作用的构造－热事件。

This paper studied the lithologic characteristics, porosity and its evaluation, forming mechanisms of six kinds of volcanic rocks, and analyzed the evaluation history and the key factors about the main volcanic reservoirs, including andesite, basalt and tuff, etc.

对研究区火山岩岩性特征、储集空间类型、孔隙演化特征及其主要影响因素进行了深入分析，研究了区内6种火山岩的岩性特征及4个亚类储集空间的发育特征，深入分析了区内主要的火山岩储层如安山岩、玄武岩、火山角砾岩和凝灰岩等的孔隙演化过程及其控制因素。

The evolution history of the volcanic rocks goes through five stages, the forming stage, the weathering and leaching stage, the burial and tectonic\|reforming stage, the erosion stage and the oil and gas accumulation stage. Finally, the model of porosity evolution was set up with andesite and basalt as examples.

在上述研究的基础上，将火山岩储集空间的演化过程分为火山岩的形成阶段、风化剥蚀淋滤阶段、埋藏和构造作用阶段、溶蚀改造作用阶段和油气聚集成藏阶段5个阶段，并以安山岩和玄武岩为例，建立了火山岩储层的孔隙演化模式。

Based on major and trace elements and isotope geochemical data, it is inferred that Sandouding suite is formed by magma melting of Late Archeozoic continent tholeiite source, and its geochemical variation is controlled by hornblende fractional crystallization. Besides fractional crystallization, the geochemical variation of Huanglingmiao suite is related to the mixing between dacitic magma and felsic magma. Dalaoling suite is probably derived from early Precambrian volcanics.

根据岩石化学和同位素组成推断，三斗坪岩套的源岩主要是晚太古代大陆拉斑玄武岩，母岩浆相当于英安质，岩套内的成分变化主要受角闪石分离结晶作用控制；黄陵庙岩套除受分离结晶作用影响外，成分变化主要与英安质母岩浆和某种长英质岩浆的混合有关；大老岭岩套的源岩亦为早前寒武纪火山岩。

That is to say, the Cenozoic alkaline basalts were more or less modified by some enriched Sr-Nd isotopic components during their eruption.

同时，拉斑玄武岩不是碱性玄武质岩浆直接结晶分异的产物，亦不是完全由部分熔融程度的不同造成的。

Up to date the reserves discovered at shallow targ ets has exceeded 70% of total in Bohai Sea.Neotectonismis chara cterized by:(1)different Q and N center of subsidence,and angular unconformity b etween Q and N;(2)basalt effusion and magma activities frequently;(3)regular dis tribution of earthquake center;(4)intensive later faults (15-2Ma)forming multit ude anticiline in Nm-Ng formations.

目前浅层的油气储量占总储量的70%以上，这是由于海域新构造运动控制了晚期成藏，表现为：第四纪沉降中心与Nm晚期沉降中心不吻合，使得Q与N之间地层呈角度不整合；玄武岩喷发及岩浆活动频繁；沿渤南及郯庐断裂带天然地震震中有规律分布，晚期(15～2Ma)断裂极其发育，在Nm—Ng组地层内形成众多的背斜圈闭。

Mantle xenoliths from 12 localities in Eastern China are studied in this paper to investigate the composition, thermal structure, and Redox states of Continental Lithosphere beneath Eastern China.

本文以中国东部新生代碱性玄武岩中12个代表性产地的深源包体为研究对象，对中国东部大陆岩石圈的成分、热结构与氧化状态进行了较系统的研究。

Gold, molybdenum and tungsten contents in the samples of deep-seated Xenoliths and their host rocks from Anfeng peak were analyzed.

本文对中国东部江苏东海县安峰山一带的深源包体及其寄主玄武岩中Au、Mo、W含量进行了较系统的分析，得到较系统的基础数据。

And a darkbasaltic pebble from the cove sits on this correspondent's desk as he writes,picked up from between the narrow fishing skiffs that even today are pulled upon the beach.

这位通信者从小捕鱼船之间挑选了一块深黑色的玄武岩作为他书写时的桌子，至今，这块岩石仍在海湾的岸上。

Other revisions include a new range of wheeltrims and alloy wheels, while the list of available body colours has been extended with the addition of Basalt Grey, Electric Blue and Extreme Blue.

其他修订包括wheeltrims和一系列新的合金轮毂，而现有的身体颜色的名单已经同玄武岩灰，蓝和Extreme电蓝除了延长。

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。
