角岩

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/。

The petrophysical properties of volcanic rock reservoirs in Junggar Basin are generally characterized by the following: the acidic lava and auto brecciated lava are the best, especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts.

准噶尔盆地火山岩储层物性一般特点是：酸性熔岩、火山角砾岩最好，特别是经后期构造运动和溶蚀作用改造后的火山角砾岩；安山岩的物性总体优于玄武岩。

Fracturing of mineralization stage is found mainly concentrated in the early quartz veins or the hydrofracturing breccia in the sandy tectonic lenses, the lens-like orebody mainly consisting of the cataclastic quartz veins and hydrofracturing breccia form.

成矿阶段的破裂主要集中在砂岩构造透镜体中早期石英脉或液压角砾岩上，形成以碎裂石英脉及液压角砾岩为主要矿化母岩的透镜状矿体。

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.

本文首先简要介绍节理形貌的描述方法和分形几何理论，然后将分形理论引人岩体节理摩擦角的研究中，得出了用分形维数表示摩擦角的经验公式。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
