拉斑玄武岩

The research results indicate that the volcanic rocks in the studied abea are composed of two different kinds of association: Tholeiitic series and calc-alkaline series (basalt, andenite, dacite and rhyolite ).

结果表明，研究区火山岩由拉斑系列大洋玄武岩和钙碱性系列岛弧玄武岩、玄武安山岩、安山岩、英安岩和流纹岩组成。

The Yiyang paleovolcanic suite in Hunan is recognized at Shizuitang and Dadukou, Yiyang City, Hunan Province, covering an area of about 1km^2 and 16km^2 respectively. The volcanic suite consists predominantly of komatiites and tholeiites.

湖南益阳古火山岩分布于益阳市石咀塘和大渡口两地，出露面积分别约为1km^2和16km^2，主要由科马提岩类和拉斑玄武岩类组成。

The petrology and geochemistry indicate that the protoliths of aluminum-rich gneisses are aluminum-rich pelitic and pelitic arenaceous sedimentary rocks, the protoliths of basic granulites are continental tholeiitic basalts. Therefore, the khondalite series may be produced at continental margin.

岩石学及地球化学的初步研究表明富铝的片麻岩的原岩为富铝的泥质和泥砂质沉积岩，所夹基性麻粒岩的原岩可能为大陆拉斑玄武岩，这套孔兹岩系的原岩可能形成于大陆边缘环境。

Petrologic studies indicate that they belong to tholeiitic series, calcalkaline series and kalibasalic series respectively.

岩石化学研究证明，它们分属拉斑玄武岩系列、钙碱性系列和钾玄岩系列。

His paper reports the petrological and geochemical characteristics of Permian alkaline and tholeiitic basalts in the Shuanghu Area, central Qiangtang Block.

对青藏高原羌塘地块中部双湖地区发育的二叠系碱性系列和拉斑系列玄武岩进行了详细的地球化学研究。

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。

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。
