What is the glass meteorite and what is its cause?

Speaking of glass meteorites, many people may not know exactly what kind of existence it is. Is it a glassy meteorite? Today, Xiaobian takes you to explore what is the glass meteorite and what is its cause?

Scientific research has confirmed that glass vermiculite is a liquid-cooled product that is ablated during the decline of the stone. But it does not belong to the stone.

Glass vermiculite is a translucent glass body with weak magnetic properties, such as dark green, green, light green, brown, brown, dark brown, and rare cinnabar. The specific gravity is 2.6 to 3.0. The glass vermiculite is composed at high altitude, high temperature, high pressure and high speed, so it has a remarkable composition: the internal high purity is free of impurities, the whole body is covered with fine small bubbles, the outer part has a melting shell, and the outer shell has a flow pattern. There are sometimes large marks on the outside and under the shell.

The cause of the glass meteorite: how the glass meteorite is formed, and there is still much controversy. Some scientists think that an infinite meteorite or comet (nuclear) hits the earth, melting the surface material of the earth, sputtering it into the air, and rapidly cooling it. However, until now, no corresponding craters have been found for the glass meteorites in Australia and North America. From the perspective of the extensiveness of glass meteorites, this concept is also questionable.

Some people think that the glass meteorite is the glass rain that descends from the space to the earth's atmosphere, and even some people have witnessed the decline of this glass meteorite. Glass gangue is brittle and has a shell-like fracture after breaking. The size of the glass meteorites found on the interior ranges from a few millimeters to a dozen centimeters. The reflected light is dark, but the thin margins are translucent and have different colors, from yellow to green, from olive brown to dark brown. Microglass vermiculite is found only in marine sediments, and its size ranges from a few millimeters to less than about 40 microns. It has the same age, composition and shape as the glass meteorites on the adjacent inland.
