[Name] Glass meteorites from Mars
[Specification] Weighs 244.7g
Meteorites are unburned materials made of stone, iron or a mixture of iron and stone that are scattered rapidly to the surface of the earth or other planets by cosmic meteors or dust fragments that have left their original orbits outside the earth. After the glass meteorite falls to the earth's surface, it produces the high temperature to melt the surface mineral, after cooling the product, belongs to the secondary derivative, it is essentially the earth's surface silica is not the extraterrestrial meteorite. The glass meteorite is a kind of stone meteorite associated with it. British biologist Charles Darwin acquired a button-shaped glass stone in Australia in 1844. In the international scale, this kind of glass stone is known as "glass meteorite". It is a natural glass substance.
It is also called obsidian because it looks like obsidian. But the composition and structure of both are different. Most glass meteorites have shapes similar to those of molten sputtering objects, including spherical, elongated, dumbbell-shaped, droplet shaped, button shaped and irregular lumps. It is scattered in swarms in sediments on the inner ground or on the sea floor. The color of glass meteorites are black, dark green, brown, surface with elongated bubbles and size of the bubble, some like the lunar appearance of the craters like patterns. Most of the shape of glass meteorites and molten sputtering similar shape, often black or dark green, translucent, formerly various shapes of glass meteorites throughout is believed to be formed by meteorites, large meteorites impact the surface and meteorite fragments quickly melt, agile cooling crystallization. The origin of the glass meteorite is now known, it is a kind of stone meteorite rapid fall after the product of melting. Although most scientists now believe it was formed when an infinite number of meteorites or comets (nuclei) smashed into the earth, causing the material on the earth's surface to melt and splash into the air, rapidly cooling. There are two hypotheses about the formation of glass meteorites that are closest to the facts. The most likely scenario is that glass meteorites are large meteorites or comet cores that hit the earth, causing molten rock on the earth's surface to spewing out of the crater and rapidly cooling. Or glass meteorites formed from rain of glass falling from space into the earth's atmosphere.
