变质

Genetic analysis suggests that tourmalines were formed during regional metmorphism of amphibole facies.

经成因分析，电气石是由角闪岩相区域变质作用形成的

And in lower crust, about 20-25km depth, due to the time detained was relative long, the amphibolite facies metamorphism happened.

而在20-25km的中、下地壳层位，由于滞留的时间较长，这些花岗岩则发生了角闪岩相变质作用。

Based on the mineral distribution and assemblage in the run products at 1035 GPa and 950 ℃ for 20300 h, the textural development of amphibolite during the partial melting process, the metamorphic reaction, and the garnet corona generation are discussed.

依据实验产物的矿物组合和新生矿物的分布特征，讨论了950℃、10~35 GPa、恒温(20~300 h)条件下，斜长角闪岩部分熔融过程的结构变化、变质反应以及石榴石冠状体的成因。

Within the granite particularly its eastern part, it is frequently met that gneiss which has its original occurrence, and granulite and amphibolite enclaves as well.

岩体中还广泛分布着各种类型的变质基性岩石包体和岩片，在东部具有明显的"成群成带"分布特点，边缘地带也较为多见。

The regional metamorphosing-crystallization is divided into three mineralization stages which are low amphibolite facies, high greenschist facies and low greenschist facies.

区域变质－结晶成矿期又分为与低角闪岩相、高绿片岩相和低绿片岩相对应的3个成矿阶段。

Using conventional garnetbiotitemuscoviteplagioclasequartz geothermobarometry, pT conditions were estimated to be 590610 ℃ and 0.951.14 GPa for the Huilongsi Formation, and 630650 ℃ and 0.650.89 GPa for the Zuolaozhuang Formation, in agreement with lower and upper amphibolite facies, respectively.

运用传统的石榴石黑云母白云母斜长石石英地质温压计估算回龙寺组的变质pT区间为590～610 ℃、095～114 GPa，左老庄组为630～650 ℃、065～089 GPa，分别相当于低角闪岩相和高角闪岩相。

During the evolution of these granitoids which resulted from rejuvenation and anatexis of the old basement (1200-2000Ma), the main ways for REE differentiations were:(1) partial melting;(2) fractional crystalization;(3) thermogravitational diffusion;(4) differentiations of metamorphism and migmatism, and (5) hydrothermalism.

在花岗岩的形成和演化过程中，有五种最主要的方式造成REE的分馏作用：(1)部分熔融作用；(2)分离结晶作用；(3)热重力扩散作用；(4)变质-混合岩化作用和(5)热液流体作用。

The chemical composition of Pingyang gneissic granite with high contents of SiO〓, Na〓O, Sr and Ba was inherited and developed from that of mainly biotite gneiss through anatexis under the background of regional migmatisation, it might also be introduced the fluid material from deep.

平阳片麻状花岗岩的化学成分是在区域混合岩化对岩石成分总体改造趋势的背景下，在黑云斜长片麻岩成分的基础上，通过黑云斜长片麻岩的深熔以及可能的变质脱水反应流体和深部流体的加入演变而成，富SiO〓、Na〓O以及Sr和Ba。

Give the age of regional metamorphism not younger than 2.55±0.04 Ga, and those of the anatectic rock of granodioritic composition collected just east of Xiaojue, value of 2.47±0.09 Ga for the age of anatexis.

测定结果说明小觉及其以东地区三种岩石所经历的区域变质作用的年龄，不小于2.55±0.04 Ga，小觉附近深熔岩石的深熔年龄为2.47±0.09 Ga。

In the west of Beijing, a form of andalusite JiaoYan of chrysanthemum stone, distribution in lime department carbonaceous contact metamorphic belt.

产于北京西山的一种由红柱石角岩构成的菊花石，分布于石灰系碳质板岩的接触变质带。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
