Glass meteorite is the product of liquid cooling during the falling process of some kind of meteorite. The mother rocks of glass meteorites are light green and black. Therefore, the falling of glass meteorites is carried out together with the mother rocks.
There is a record of glass meteorite in the book "record of mountains" written by Liu Xun of Tang Dynasty in China: "after the thunderstorm in Leizhou, people get the stone in the wild, which is called LEIGONGMO. And it's so lovely. " Because glass meteorite is formed at high altitude, high temperature, high pressure and high speed, it has obvious formation characteristics: high purity inside, no impurities, the whole body is full of dense small bubbles, the outside has melting shell, there are flow lines on the melting shell, and sometimes there are large air marks on the outside and under the melting shell. The shape of the glass meteorite is in the shape of a round cake. The surface is black. There are elongated bubbles and round bubbles of different sizes on the surface. Some of them look like crater like patterns on the surface of the moon. The melting shell shines with dazzling light in the sun, which is very precious. The burning trace of the meteorite is obvious, and the gas seal is dense and beautiful. It is the product of liquid cooling during the falling process of the meteorite. It is called tianwai noble guest and has high scientific research, ornamental and archaeological value.
Glass meteorite is a semitransparent vitrinite with weak magnetism. Its color is dark green, green, light green, brown, brown, dark brown and rare cinnabar. The specific gravity is about 2.6 to 3.0. Glass meteorite is formed at high altitude, high temperature, high pressure and high speed, so it has obvious formation characteristics: high purity inside, no impurities, the whole body is full of small dense bubbles, the outside has melting shell, there are flow lines on the melting shell, and sometimes there are big gas marks on the outside and under the melting shell.
Because glass meteorites are liquid bodies in the process of falling, they will be decomposed into smaller mass bodies at high speed, so there is no glass meteorite of great mass objectively, but it may be larger mass body when it falls with parent rock. Therefore, glass meteorites are of great scientific research value. According to the records of extraterrestrial objects in the United States, glass meteorites are no more than 40000 rose in the world, and the precious glass meteorites are extremely rare, which are generally searched by developed countries. In order to study the use of outer space, some of them are exhibited in national museums, and few of them are successfully collected by large collectors due to their fate. Glass meteorites have great collection potential, In the future collection market value is immeasurable!
Since the 1970s, the price of meteorites has been almost the same as that of gold. Subsequently, it continues to appreciate at an annual growth rate of 30% - 50%. Nowadays, the most common meteorites can also be sold to US $500-600 per gram, while rare meteorites can reach US $3000-8000 per gram, and even US $100000 per gram. As early as 2001, China's investor Daily reported that meteorites had beaten diamonds, mink fur and methamphetamine in the price ranking of international smuggled goods, ranking first. According to data statistics, there are countless meteorites falling to the earth every year, but most of them fall into the ocean and desert areas, which are very little known and collected by people. According to rough statistics, about 500 meteorites hit the earth every year, only 20 can be found, so they are extremely rare and expensive. For a long time, meteorites have been highly praised by many astronomers and geologists for their high scientific research value. Moreover, because of their peculiar shapes and origins in the universe, they have added a sense of mystery and become objects that people are competing to collect and watch. The glass meteorite weighs as much as 7298g and has a large volume. It is a rare meteorite that can not be found. Its price is very high and it is worth collecting.
