introduce: Glass meteorite is a kind of meteorite associated with some kind of Stone. The British biologist Darwin obtained a button-shaped vitreous Stone in Australia in 1844. Later, this kind of vitreous Stone was commonly called "glass meteorite" in the world. Don't think it is the kind of glass at home when you hear glass, it is a natural glass substance. Because it looks like obsidian, it is also called obsidian. But the composition and structure of the two are different. The shape of most glass meteorites is similar to that of molten sputtering, including spherical, elongated, dumbbell, droplet, button, and irregular lumps. It falls in groups on continents or in seabed sediments. The colors of meteorites are black, dark green, and Brown. The surface layer has elongated bubbles and bubbles of different sizes. Some of them look like crater-shaped patterns on the surface of the moon. reach higher values. Meteorites are solid substances that fall from outer space to the ground. The craters on the surface are caused by high-temperature melting when passing through the atmosphere. There is also a saying that when a huge meteorite hits the ground, it makes the surrounding The rocks were melted or dispersed due to the high temperature effect after the impact, and formed pits on the surface after cooling. As for which statement is more correct, the current science cannot yet verify it. Because meteorites fall into the earth at high speed from space, high-temperature friction will be generated when passing through the earth's atmosphere, causing the meteorites to exhibit high-temperature melting characteristics. Therefore, the surface of relatively fresh meteorites generally has a thin layer of fusion crust, and the color is mostly gray, black or dark brown. Some surfaces are relatively smooth, some have concave air marks, some are covered with densely packed small holes, and some have cracks due to thermal expansion and contraction. The relatively fresh meteorites that have just fallen are generally easier to identify. They usually show a very perfect molten appearance, and some fusion crusts and gas marks will be more obvious. The characteristics and identification methods of glass meteorites are as follows: 1. Surface fusion crust: Meteorites have to pass through the dense atmosphere before falling to the ground. During the landing process, meteorites rub against the atmosphere to generate high temperature, which melts the surface and forms a thin fusion crust. The surface is mostly distributed with different sizes and depths. Unequal pits, that is, erosion pits. Due to the denudation of the molten material when the meteorite passes through the atmosphere, its surface has a rhyoid or shallow and elongated melt streamline structure. 2. Surface air imprint: Due to the interaction between the meteorite and the atmospheric air flow, many air imprints will be left on the surface of the meteorite, just like the fingerprints pressed by fingers. In addition, some meteorites can see many "small bumps" or "small balls" of different sizes with the naked eye. 3. The natural glass meteorite Tektite is very similar to the Czech meteorite. The edge of this piece is green, but the whole is opaque. This piece of black glass meteorite Tektite has a density of 2.458. There is a melting shell on the outside, and there are flow lines on the melting shell. Sometimes there are obvious air marks on the outside and under the melting shell. The edge is green, but the whole is opaque. Use a 20x magnifying glass The natural features are even more evident in the next photo, which is very beautiful and natural. It cannot be imitated by current technology, and it is absolutely fidelity! https://youtube.com/watch?v=OwRGgmXFyXA&feature=shares
