These crystals were fashioned in excess of a million many years ago inside the Earth's crust. They take place once the liquid inside the Earth consolidates and also the temperature chills. Other crystals form in the event the liquid will make its way from the clefts and dispense minerals in the clefts.

23Sometimes, on the other hand, the crystal method of the silicate inclusions is noticed to resemble a lot more carefully The inner construction of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。

Chemical Bonds The types of chemical bonds fashioned involving atoms or teams of atoms in crystals rely on their dimension and electronegativity. You'll find four classes of crystals as grouped by their bonding:

养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。

C2 [ U ] clear glass of really high quality, commonly with its floor Slice into fragile patterns:

你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。

⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。

There exists a equivalent directive about crystal glass which differentiates concerning complete guide crystal, lead crystal and crystal.

水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

crystal The freshly crystallized quartz grains are characterized by elongate crystals oriented oblique for the shear band margins, defining a typical grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology inside the large w area acts as being the proverbial ' scratch-on-theglass ' needed in the natural and organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter among the person crystals might replicate incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, from time to time that contains inclusions of plagioclase microlaths and opaque phases.

被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。

This Review chronicles about twenty years of exploration into creating a genetic code for crystal engineering. Rather than directing biological processes, this code makes use of synthetic types of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which nearly each individual facet of the resultant buildings might be systematically controlled. Within just this conceptual framework, the structural and functional improvements are described in an effort to define the existing degree of sophistication and to predict foreseeable future Instructions of the platform.
