The present invention is concerned with a method for the extraction of magnesium from magnesium-containing materials such as magnesite, dolomite and silicates materials like serpentine residues, products from the amphibole or pyroxene group.

本发明涉及一种从含镁原料萃取镁的方法，该含镁原料包括菱镁矿、白云石、含镁硅酸盐物质象蛇纹石残渣，来自角闪岩及辉石类的产品。

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 this relationship, the v of the amphibolite obtained is 6.390 7 km/s, and the pressure coefficient is 0.160 6 km/.

依据该线性关系，得到常温常压下斜长角闪岩的弹性波纵波速度为6.390 7 km/s，压力系数为0.160 6 km/。

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。

We have performed partial melting experiments on a massive amphibolite sample under 1.5 GPa and 950 ℃ for 101 hours: the sample was collected from Archaean terrain in the northern margin of the North China craton.

在1.5 GPa，950 ℃，恒温101 h条件下对华北北缘太古宙地体中的斜长角闪岩块状样品进行了脱水部分熔融实验，实验产物组合为Hb+Cpx+Gt+Gl，获得的熔体为花岗闪长质成分。

These amphibolite samples have very high initial eHf values of+15.2 to +23.3 and the eHf values are tightly correlated with eNd values.

这些斜长角闪岩有异常高的εHf比值(+15.2～+23.3)，且εHf比值与已发表的εNd比值表现出良好的正相关(r~2=0.81)。

The hypo-volcanic crytoexplosion Breccia rock body is formed of granite magma, which is rise to the lower of the earth s crust along the east-western shear zone and exploded below the Archean fundus rock. The felstone vein and the hypo-volcanic crytoexplosion Breccia rock are from the same magma source, and are formed in the different evolution stages.

香炉碗子金矿区分布的次火山隐爆角砾岩体是由花岗质岩浆沿东西向脆～韧性剪切带上升到地壳浅部隐爆太古代基底岩石所形成，霏细岩脉与次火山隐爆角砾岩来自同一岩浆源，为同一岩浆活动不同演化阶段所形成的。

At least, three types of earthquake related fault rocks including pseudotachylyte formed by typical fast fault movement, no orientated ultra-cataclasite or sinter breccias may formed by weak earthquake faulting, and stockwork microbreccias formed by autochthonous powerful shock at the source are discovered, in which some of the original sources parameters are remained.

至少区分出三种地震断层产物和两种震源破裂方式：典型快速地震断层形成的假玄武玻璃；或许与弱震有关的无组构超碎裂岩或熔结角砾岩，以及强烈原地震动成因的网脉状微角砾岩。

In this Paper the joint profile expression and fractal theory are reviewed, and the fractaltheory is used to study the frictional angle of the rock joint.
