玄武岩

The greenstone belt is a typical volcanic-sedimentary formation formed by metabasic-acid volcanic rocks and partly metasedimentary rocks. The bimodal volcanic rocks are mainly tholeiite, which transforms upward into calc-alkali volcanic rock series.

绿岩带为典型的变质基性－酸性火山岩及部分变质沉积岩系构成的火山-沉积建造，火山岩以拉斑玄武岩为主，向上过渡为钙碱性火山岩系列，表现为双峰态型特点。

Of them, we proposed the term of the Toyon volcanogroup in the first time. All the volcanoes can be subdivided into two types: central-eruption-typeand flood-basalt-type, building a series of volcanic mechanism, including calderas, volcanicnecks and cone sheets.

托云火山岩是由多个近于同时喷发的火山口的喷出物复杂堆积的产物，这些火山口可以划分成中心式火山和溢流玄武岩两种类型，它们共同组成了托云火山群。

In 1898 alone, several million cubic yards of traprock provided building material for the growth of nearby Manhattan Island, by exploding more than150 tons of dynamite in the mountain rock.

仅1898年就有数吨炸药用来开山取石，数百万立方码的玄武岩被开采运走作为曼哈顿城区的建材。

Their multi-element distribution patterns show continental tumescence characteristics of intraplate basalt.

它们的多元素配分曲线均呈现出板内玄武岩的大隆起特徵。

In general, the composition of lower crust is close to basalt and the composition of upper crust is similar to granite.

一般来说，下地壳的成分接近于玄武岩，而上地壳的物质成分与花岗岩相似。

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

本项目立足于从火山岩属性和深源捕掳体反演源区成分与结构两个途径，利用火山岩综合研究成果对地幔源区进行了初步反演，提出源区经受过强烈钾质交代的观点；对重点工作区TM图像进行了初步解译，新发现若干了火山口，并对其中三个火山口作了实地查验，为进一步全面深入开展该区的火山地质学及相关科学问题打下了良好基础，认为托云盆地是一个火山群，而不是一个单一的火山构造盆地；系统测制了火山岩剖面，新采集了一批重要的火山岩和深源岩石捕虏体样品，为下一步工作打下基础，特别是采集到了直径打20cm的幔源橄榄岩包体，可用于各种测试，将可以结束西部造山带没有地幔岩化学分析结果的历史；对康西瓦玄武岩进行了测年分析，取得了我国目前最年轻的锆石U-Pb SHRIMP年龄，对青藏高原挽近地质时期的隆升提供了年代学约束；对帕米尔东缘塔什库尔干碱性岩体的动力学意义进行了探讨，提出青藏高原西部构造结的形成与岩浆活动有关的观点。

I read Claus Sendlinger's editorial in Choupana Hills, a Design Hotel in Madeira that makes no special claim to greenness, though its light bulbs are low-energy, its toiletries come in recycled packaging and its decor involves products from the island: basalt and wickerwork from the nearby village of Camacha, one of the many local industries tangentially dependent on tourism.

森德林格的一篇社评Choupana Hills酒店是Design Hotels酒店在马德拉群岛的成员酒店，并没有刻意标榜绿色环保，尽管安装有低能耗照明灯，卫生用品使用的是再循环包装，装饰材料产品也都来自岛上：玄武岩制品和柳条制品来自附近的Camacha村当地许多行业都多少要依赖旅游业

我曾在Choupana Hills读过克劳斯·森德林格的一篇社评。Choupana Hills酒店是Design Hotels酒店在马德拉群岛的成员酒店，并没有刻意标榜绿色环保，尽管安装有低能耗照明灯，卫生用品使用的是再循环包装，装饰材料产品也都来自岛上：玄武岩制品和柳条制品来自附近的Camacha村。当地许多行业都多少要依赖旅游业。

The methods of wide-angle seismic technology are put forward to solve this problem, taking a distinguish area of our country as an example.
