地幔岩

Seven wolframite separates from both topaz-quartz vein type and greisen block type tungsten ores were selected for Sm-Nd analysis.

云英岩型钨矿石中2件黑钨矿样品的ε(322Ma)值分别为5.93和4.24，与同时期亏损地幔钕同位素演化线值接近。

In contrast, the ε(322 Ma) values of five woiframite separates from the topaz-quartz vein ores range from -4.16 to -8.05, much lower than values of the greisen massive ore.

云英岩型钨矿石的形成作用与亏损地幔源岩浆活动有关，而黄玉－石英脉型钨矿石则很可能是壳源岩浆活动的产物。

In contrast, the two rock associations at the south belts were derived from mesomatised lithospheric mantle. However, the ultramfic-alkaline rock association was resulted from immiscibility of parent magma, whereas sodic alkaline rocks were produced by highly differentiation at deep level.

南部的两种岩石组合类型均起源于岩石圈地幔，并在部分熔融之前发生过交代富集作用，但是超镁铁质岩-碱性岩组合为原始岩浆经不混熔作用形成，而钠质碱性岩是原始岩浆在深部经历了高度分离结晶的产物。

Rare samples of mother rock 'kimberlite', from Siberia, South Africa and Australia, displayed as an introduction to the geological section of the museum,- how diamonds originate from a volcanic magma, formed in the earth's mantle, 100 - 200 km below the earth's surface, and are transported through volcanic pipes to the earth's surface.

陈列了来自西伯利亚、南非和澳大利亚的罕见的金伯利岩样本。通过对它们的地质解理面的介绍，来说明钻石在火山岩浆中的形成过程，即钻石是在100~200公里的地幔中形成，随着火山爆发被喷射到地球表面。一个显示全世界钻石产量的模型（0.4立方米大小）是博物馆的精粹，就这0.4立方米的钻石，养活着全球200多万钻石业人。

They arise mainly in the form of ophiolite melange, or enter into mantle with the subduction.

洋盆地层带特别是洋壳部分则很少被保存，多以蛇绿混杂岩的形式出现或被俯冲进入地幔。

In four-facies peridotite, clinopyroxene contains abundant information concerning partial melting and mantle metasomatism due to its low melting point.

在无水"干"体系的四矿物相橄榄岩中，单斜辉石由于熔点低而通常记录着丰富的部分熔融作用和地幔交代作用信息。

Dissipative structure has been applied in the study of dissociation of minerals, dynamics of hydrothermal mineralization, genesis of migmatite, structure and motions of the earth' s crust and mantle and so on.

耗散结构已应用于矿物离解过程、热液成矿作用动力学、混合岩成因以及地壳地幔的结构和运动等的研究。

Origin of diamonds in ohromitites of the Luobusa ophiolite, South Tibet, China.

西藏蛇绿岩中不寻常的地幔矿物群，中国地质，30(2)：144～150。

A group of mantle minerals containing about 70～80 subtypes of minerals have been discovered from podiform chromitite s in the Luobusa ophiolite, Tibet, China, in which the alloys attract the attention of geologists.

从西藏雅鲁藏布江蛇绿岩带的罗布莎豆荚状铬铁矿床中，揭示出包含 70～ 80种矿物的一个地幔矿物群，其中特别引人注意的是含有多种合金。

The outgas types and amount of different gas resource varied with the different geological conditions and evolution processes. There are four outgas models including the model in which inorganic gas directly overflows from mantle matter through lithospheric fracture,the model of heat flow piercement outgas,the model of volcano-magma outgas,and the model of carbonate rock outgas due to heat metamorphism.

对气藏成藏条件和深部壳幔结构的研究表明，松辽盆地存在多种类型无机"气源"，由于赋存的地质条件和演化过程不同，不同气源脱气的方式、脱出气体的类型、脱气量也大不相同，共有4种主要的模式：地幔物质沿超岩石圈断裂直接脱气模式；热流底辟体脱气模式；火山—岩浆成因模式；碳酸盐岩热变质成因模式。
