花岗岩

The probability analysis,clusting method and trend method are applied to study the distribution of isotopic age data of granitic rocks in time and space.

本文应用概率分析，聚类分析和趋势分析方法研究了华南花岗岩年龄值的时空分布。

This paper discusses four series of red, black, green and white granitic rocks, which include more than ten kinds of granitic rocks.

本文讨论了朱阳地区红、黑、绿、白色4大系列和十余种花岗岩石材品种。

In Nanling Mountain area, a very important metallogenic province of China, the various granitic rocks with different ages are widely distributed.

南岭地区广泛发育的不同时代的各种花岗岩类是古老基底(1200—1800Ma)活化重熔的产物。

Its mineral composition may have different combinations of terms of feldspar, quartz-based, and granite is similar to "the granitic pegmatite."

其矿物成分可有不同的组合，若以长石、石英为主，与花岗岩相似，称"花岗伟晶岩"。

Their formation is not only directly related to granitic intrusions but also controlled by factors such as regional strata and geological structure.

对湘南锡矿形成的地质背景和找矿方向进行研究，不仅能解决锡矿找矿中存在的许多重要的科学问题，为进一步寻找锡矿资源指出方向，而且对认识湘南地区地质构造演化史、探讨花岗岩类及其锡矿床的形成环境也具有特别重要的意义。

Among the three types of parent material,the yield of rape( above-ground dry weight) was the best(NPK treatment was the best in purplish soil ), Quaternary red soil and in granitization red soil were followed respectively(both of the two types of parent material have weak growth vigor and have a consistent yield). 2.With plant rape,NPK treatment could get more harvest among the three types of parent material , M treatment and CK were followed restectively.

结果表明：1、三种母质以紫色土油菜产量为最高（紫色土以NPK处理为最高），四纪红土次之，花岗岩油菜产量为最低（二种母质油菜生长均不好，产量差不多）。2、三种母质种植油菜均以NPK处理为最高。

However, there are considerable differences in their initial Sr and oxygen isotope compositions, indicating that the monzogranite was not derived from the granodiorite.

然而二者的初始Sr同位素组成存在一定的差异，表明二长花岗岩并非是花岗闪长岩分异作用的产物。

In order to study the mechanism of crack extension by hyduaulic fracturing , the mass hyduaulic fracturing experiments were carried out in granodiorite rockmass at Fangsan, Beijing, China.

为了研究水压致裂过程中裂缝的扩展机制，在北京房山花岗岩体中开展了大型水压致裂试验。

It has been realized that the TTG rock series are ancient plutons of tonalite, trondjemite, and granodiorite with continuous evolution tendency.

依据岩体低的稀土总量，明显的正Eu异常及Cr、Ni含量与我国华南同熔型系列花岗岩相似。

To study the mechanism of crack extension by hyduaulic fracturing, the mass hyduaulic fracturing experiments are carried out in granodiorite at Fangshan District, Beijing, China.

为研究水压致裂过程中裂缝的扩展机制，在北京市房山区花岗岩体中开展大流量水压致裂试验。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
