晶石

The crystal-chemical properties and the genesis of the allanite have been disscussed, in addition, the radioative decay of Th and U and the oxidation cause rare-earth elements to be released from its lattice to d...

认为本区的褐帘石是部分变生的。变生的机理是因为其晶格中含放射性元素U，Th高，且这与褐帘石的选矿性能有重要关系。

04 Nm,respectively,were used as catalysts prepared by impregnation for amination of monoethanolamine with ammonia,and their structures were characterized.

以3种具有纳米晶相结构的丝光沸石为原料，采用浸渍法制备了乙醇胺胺化反应的催化剂，并表征了催化剂的结构，考察了丝光沸石结晶度和晶粒尺寸对胺化催化反应的影响。

This rock zone, with a NE striking, the whole length of 1 400 km and the width of 100～150 km, is characterized by not onlyalkaline rocks (analcite biotite olivine melilitites, leucititic alnoites, nephelite syenites, aegirite augite syenites, melanite syenites, riebeckite syenite and aegirite bearing quartz syenites) and alkaline granite (riebeckite granite, and aegitite augite riebeckite granite), but also a lot of syenites, monzonites and alkaline feldspar granites or miarolitic K feldspar granites.

该岩带全长约1400km，宽100～150km，不仅发育有狭义的碱性岩(方沸黑云橄榄黄长岩、白榴黄长煌斑岩、霞石正长岩、霓辉石正长岩、黑榴石正长岩和含霓石石英正长岩)和碱性花岗岩(钠闪石花岗岩、霓辉石钠闪石花岗岩)，还发育有大量的正长岩类二长岩类碱长花岗岩或晶洞钾长花岗岩。

If amethyst doesn't interest you, there are other February Birthstones such as Bloodstone and Pearl.

如果紫晶不感兴趣，还有其他的二月幸运石如血石和珍珠。

In the Cathodoluminescence images the zircons extracted from the dioritic gneiss show good crystal morphology and clear oscillatory zoning, as is the case of magmatic zircon.

在阴极发光图像中，片麻岩中的锆石具有较好的晶形，并显示出清晰的岩浆锆石韵律环带结构。

Dawsonite is an orthorhombic, hydrated sodium aluminium carbonate appearing as radial, bunchy, trichoid platy collective and so on, filling in the pores among the grains, or as replacement of feldspar and detritus partly or on the whole, dawsonite is a kind of authigenic mineral which formed latest.

片钠铝石是一种斜方晶系、含水、钠和铝的碳酸盐矿物，砂岩中的片钠铝石是最晚形成的自生矿物之一，一般以放射状、束状、毛发状、板状等分布于砂岩的孔隙中或交代长石和岩屑等。

Differences of wettability and floatability between diaspore and aluminium silicate minerals are due to the differences of crystal structure between diaspore and aluminium silicate minerals, and of the part Al-O, Si-O bonds, and the metal ions on the surface of the minerals.

一水硬铝石与铝硅酸盐脉石矿物晶体结构的差异、表面断裂的Al-O和Si-O键及表面离子活性区的差别，可影响矿物表面的润湿性与可浮性，类质同象及各种晶格杂质离子也将影响浮选剂与矿物表面的相互作用和矿物可磨性。

MEp which crystallized earlier than biotite or hornblende in the magma, can not be used as a barometer, but be useful in caculating the ascent speed of magma.

作为早期结晶的矿物，绿帘石不能作为压力计来反映岩体侵位深度，因为在绿帘石晶出时，岩浆中液相体积在50%～80%，这样岩浆可能会有快速侵位的过程，但它的地质意义在于能够对岩浆上升速率做出估算。

Gem industry in often referred to as soft green fluorite crystal green, purple amethyst fluorite known as soft water.

在宝玉石界常将绿色萤石称为软水绿晶，紫色萤石称为软水紫晶。

If Smoky Quartz, Amethyst, Citrine, QUARTZ and so on.

如茶晶、紫晶、黄晶、芙蓉石等等。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
