花岗岩

In this paper,the experimental study result of the dissolvable alkali is presented.

花岗岩本身含有5%～10%的碱，这些碱有一小部是可以参与碱骨料反应的，它对花岗岩骨料的碱活性会产生一定的影响。

Besides,Qaidam granitoid in the ZWL belt western also be discussed,it belong to granitoid emplaced in the late orogenic Eopaleozoic.

此外，还对出露于宗务隆带西段的柴达木花岗岩进行了讨论，它属于早古生代造山后侵位的花岗岩。

Let us go back to the boundary of granite and foliated granite and observe their contact relation.

我们再转回到花岗岩与片理花岗岩的接触处，去观察一下二者之间的接触关系。

Over there, it has been grading into foliated rock with its color and composition similar to those of granite.

而在那边，花岗岩逐渐过渡成颜色和成分与花岗岩相似的片理化岩石。

After 1990's, the study on granites performed in international and domestic geological field reached a new climax, and focuses on the two main aspects: the genesis and the subsequent geodynamic evolution.

进入20世纪90年代以来，国际、国内掀起花岗岩的研究的高潮，目前的研究主要体现在花岗岩的成因和以此来探讨地球动力学演化两个领域。

According to the research of the paper, the "migmatite" of the Sizishan Formation, Xingdong Group distributed in northern Xiao Hinggan Mountains should be a suit of gneissic quartz monzonitegranite intrusions. Their whole rockmineral Rb-Sr isochronic dating is (482±19) Ma, indicating that an Caledonian magmatic events existed in the giant granitic belt of the Xiao Hinggan Mountains.

研究表明，分布于小兴安岭北部金林林场的兴东群四子山组&混合岩&为一套片麻状石英二长岩-花岗岩侵入体，岩石全岩-矿物Rb-Sr等时线年龄为(482±19) Ma，这表明小兴安岭巨型花岗岩带中存在早古生代岩浆事件。

So the meta-granitoids can he recognized and separated from the metamorphic sequences. They are grouped as the Meoproterozoic-Neoproterozoic gneissoid granite-monzogranite-granodiorite, with their isotope ages of 953.4 Ma to 1450 Ma, and the Sinian schistostose quartz monzogranite diorite.

主要成岩期及代表性岩类有：晚元古代为片麻状正长花岗岩－二长花岗岩－花岗闪长岩，同位素年龄为953.4~1450Ma；震旦纪为片理化石英二长岩－石英闪长岩，同位素年龄为547Ma。

Our results indicated that REE concentrations of groundwater within the granitoid weathering crust in Baisha area are high relative to many groundwater samples within granite weathering crust worldwide.

本文研究了广东省白沙地区花岗岩风化壳地下水的水化学特征，特别是与花岗岩的风化过程有关的稀土元素含量及其分布模式。

This conclusion provides an explanazation for the genetic connection between granitoids and gold deposits. It shakes the traditional but still prevalent viewpoint of taking a close spatial relation between granitoid and gold deposits as a genetic connection.

这一认识为花岗岩与金矿的成因关系提供了一种解释，动摇了目前流行的把金矿与花岗岩密切的空间联系当作成因关系的传统认识。

According to the SHRIMP research of inherited zircons in the granitoid in Zhaoyuan-Laizhou area, it is showed that lots of different age′s inherited zircons are there.

招远—莱州地区花岗岩类锆石SHRIMP 研究表明，该区花岗岩类含有大量不同时代的继承锆石。
