17These rings are indicative of the crystal composition of nickel and might be explained only by invoking wavelike Qualities of light.这些光圈表明了了镍的晶体结构,而且只能通过光线中波的特征来解释。

一般而言,紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅,颜色较深的为A级,稍浅的为B级。一般颜色较深的价格高,但要以不深暗为标准。颜色包括两种,一种是水晶本身的颜色,另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正,分布要均匀,不能太深或太浅,如澳州玉、蓝玉髓、紫晶、黄水晶,其价格就高。无色的水晶内含包裹体的颜色艳丽,其价格也高,如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。

We have penned about around 300 stones in the mineral kingdom! Read about Each and every stone's distinctive origin, historical past, and energies beneath.

Crystalline composition is characterized by a geometrical, repeating sample of symmetric molecular structure. The arrangement of atoms varieties these requested, repeating styles.

These examples are from corpora and from resources on the web. Any viewpoints during the examples usually do not depict the impression in the Cambridge Dictionary editors or of Cambridge College Press or its licensors.

Crystals glance exceptional from many other rocks and minerals, but �?barring some special circumstances �?almost all minerals conceal a crystalline structure beneath the surface.

水晶常以晶簇、晶洞形式产出,其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙,当富含硅质矿物的流体进入较薄的熔岩孔隙中,且温、压条件合适时将结晶沉淀出水晶等矿物。

Crystals with obvious flat click here faces are referred to as euhedral crystals, when People missing outlined faces are known as anhedral crystals. Crystals consisting of purchased arrays of atoms that are not normally periodic are termed quasicrystals.

There's two such attainable periodic preparations. In Every single, the first layer has the atoms packed right into a airplane-triangular lattice in which each atom has 6 instant neighbours. Determine two exhibits this arrangement for that atoms labeled A

Crystallography will be the research of crystals, and it specials with every little thing from best geometric shapes to seemingly random conglomerations of particles and minerals.

The structure of the sodium atoms by itself, or perhaps the chlorine atoms on your own, is fcc and defines the device mobile. The sodium chloride construction Hence is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is based around the bcc framework; every single other atom is cesium or chlorine. In this instance, the device mobile is really a dice. The 3rd essential structure for AB

矿物成分:针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶,如发晶、钛晶、绿幽灵等,发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶;含铁�?;呈金黄色或柠檬�?)称黄水晶;含锰和钛呈玫瑰色者称蔷薇石英,即粉水晶;烟色者称烟水晶;褐色者称茶晶;黑色透明者称为墨晶。
