查询词典 granites

The results show that A-type granites in eastern China are of diverse crustal origins. They were either derived from anatexis of old lower crust or resulted from partial melting of recycling juvenile altered oceanic crust, and the latter has net contribution to the continental growth.

结果表明，中国东部A型花岗岩物质来源具有多样性，既可起源于古老下地壳深熔作用，也可由再循环年青蚀变洋壳通过部分熔融产生，后者是大陆生长的重要方式之一。

The Beilekuduke biotite granites in the study area have long been thought to be of S-type.

初步研究表明，长期以来被认为S型花岗岩的贝勒库都克黑云母花岗岩应为铝质A型花岗岩。

There some biotite granites belong to the transitional granite between I-and S-type.

同时有一些黑云母花岗岩属于I型和S型之间的过渡类型。

According to these analyses, this thesis discusses the genesis of the Caledonian granites in the studied area.

The identification of the Early Caledonian granites is of important significance in studying the geological tectonic evolution of the area.

早古生代花岗岩的确认对该区地质构造演化研究具有重要意义。

Two types of gold deposit may be generally identified on the basis of Au minerallization related to some Caledonian granites, and each has its prospecting districts respectively put forward in the thesis.

另外，本文在加里东期全矿化的研究和分析的基础上，对其进行了分类，并分别指出了其可能的远景区。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

The recent research shows that granitoids rocks within the ophiolites include not only the granites formed by fractionation of MORB at low pressure, but also the granites which formed by partial melting of gabbros of ophiolites in shear zone or intruded it during the formation and evolution of the ophiolite.

近年来的研究表明，蛇绿岩中的花岗质岩石不仅包括直接由大洋玄武质岩浆结晶分异形成的花岗质岩石，即传统意义上的大洋斜长花岗岩，还包括蛇绿岩在形成、演化过程中本身形成的和侵入的花岗质岩石。
