Meteorites, refers to the meteorite residue of fell to the ground, is composed of minerals such as iron, nickel, silicate, which is also called meteorite stone, also refers to contain stone more or all for stony meteorites. People in high carbon content of meteorites also found a large amount of ammonia, nucleic acid, fatty acid, pigment and 11 kinds of amino acids and other organic matter, then there are scholars think that the origin of life on earth and meteorites is considerable. And in the 70 s "meteor" this noun is new for lots of people, who will not say to collect these dark broken stone, but in Europe since ancient times has a collection of meteorites hobby, along with the increase of the comprehensive national strength of the domestic scientific research technology gradually improved, meteorites has also become a research hot, with collectors for meteorites also set off a meteorite fever.
Meteorites for translucent glass plasmids, weak magnetism, the color is dark green, green, light green, brown, brown, dark brown, and the minium rare. The proportion of about 2.6 to 3.0. Glass meteorite is formed under high altitude, high temperature, high pressure and high speed, so it has obvious form appearance: internal high purity without impurities, connect body covered with dense tiny bubbles and hearing the external melt shell, rhyolitic melt shell, external and melt under the shell sometimes produce large gas seal.
In this paper, the "glass meteorite" weighing about: about 87.5 g, irregular shape, appearance is dark green, sleek and glossy, left a meteor falling through the atmosphere by the friction produced when the flow lines and streamline after high temperature combustion. Strange shape, the fusion crust shining in the sun glare, very precious. Obvious effect of the calcination, dense gas seal beautiful, is a meteorite landing process of melted liquid mass product after cooling, the surface with elongated bubble and sizes of round bubble, some like the surface of the moon crater shape design, is very rare, has the very high scientific research, ornamental and archaeological value.
It is understood that in the 1990 s, in meteorites trade of the world's population is only about 200 people, and at present the involved has been increased to more than one。 Glass meteorite is the widening circle, and it is very rare, let glass meteorite in global prices, from a few dollars per pound, up to now the huge number of comparable to diamond。 And in recent years, domestic also gradually rise an upsurge glass meteorite collection。 Three or four years, not only the glass meteorite prices, domestic glass meteorite collection market is also increasingly forming, therefore the value of tektite is very handsome, very suitable for investment and collection。
