At present, the largest Czech meteorite is only about 200 grams, but a small piece of Czech meteorite is valuable. Usually, there are fine concave lines on the surface of Czech meteorites, which are formed when meteorites flow in the air. Under normal circumstances, the original ore appearance of all meteorites must be uneven, unless it is artificially polished. Thicker Czech meteorites will appear dark green with some black, while thinner Czech meteorites will appear light green. But if they are transparent, they will all appear different shades of green without black. In fact, Czech meteorite is a special kind of natural glass. Czech meteorite looks like green translucent glass, which is a very rare substance. Its appearance often has a very special carved pattern, which is often directly used to inlay jewelry (unprocessed). Because it is natural glass, it is as brittle as glass, and there is a high probability that it will crack during processing, so it is not easy to carve and shape. Therefore, the finished products processed by Czech meteorites are more expensive.

Because the glass formed by meteorite impact is extremely special, it is considered to contain extremely high cosmic energy, which can provide energy to get rid of headache, fatigue and listlessness and enhance the human immune system. Green meteorites have very, very strong magnetic fields.

Stone-iron meteorite is composed of iron, nickel, silicon, acid and salt minerals, and the metal content of iron and nickel is 30%~65%. This kind of meteorite accounts for about 1.2% of the total number of meteorites, so it has the highest commercial value. The famous stone iron meteorite is the "Iron Bull" in Junan, Shandong Province, with a length of 1.4m and a weight of 3.72 tons, ranking first in the world. The iron content of this meteorite is more than 70%, followed by silicon, aluminum and nickel. The main minerals are pyrite, porphyry and rhyolite. The secondary minerals are meteorite pyrite, chromite and graphite.

According to its internal main components and structural characteristics, stone-iron meteorites can be divided into olivine stone-iron meteorites and bronze pyroxene lepidolite-iron meteorites. Stone-iron meteorites can create great commercial value, and it is of great significance for human beings to carry out research and analysis on such meteorites.

The iron cow stone iron meteorite in Junan, Shandong Province is brown, half hidden and half exposed, lying in the north and south. The northern end of the bull's head is high, staring into the distance, as if absorbed. The head of the cow is about 70 cm off the ground, and the middle of the cow is slightly lower, about 40 cm off the ground, forming a complete cow back. The southern end is slightly higher than the middle, about 50 cm from the ground, and it is a cow's ass. The whole meteorite has a proper proportion and looks like an "auspicious cow", which has become a symbol of strength and courage. According to experts' determination, the total length of the meteorite including the underground part is 140 cm, the maximum width is 80 cm, the upper and lower thickness is generally about 40 cm, the maximum thickness is 80 cm, the volume is about 0.6 cubic meters, and the weight is 4 tons. The surface structure of Tieniushi Iron Meteorite is rough, with wide pores and uneven pore density. The pore size is generally 1 cm ~2 cm, and the maximum is 10 cm. The main component of meteorites is iron, and the composition of iron is about 70% or more. Followed by silicon, aluminum, nickel and so on. , but also contains a small amount of chromium, phosphorus, sulfur and carbon components. The main mineral components of this meteorite are flint, flint, rhyolite, clinopyroxene and syenite, and the secondary mineral components are meteorite pyrite, meteorite phosphorus nickel ore, chromite, graphite and magnetite.

According to the composition and structure of Tieniu meteorite, it belongs to stone-iron meteorite. Most of the meteorites people see at home and abroad are black, while the color of Tieniu Stone Iron Meteorite in Junan is only yellow. Why is this? The reason is very simple: the areas where Tieniu Stone Iron Meteorite falls are mostly loess layer and yellow mud geology. No matter where it is hidden, it is inevitable to print yellow on the surface of the meteorite, especially under the action of high temperature, the molten shell and loess (mud) fuse to produce a unique yellow molten shell color. Together, these factors make the Junan Tieniu Stone Iron Meteorite not only have the world's largest laurel, but also have a unique temperament. This black meteorite is particularly precious in Tieniu's hometown, and spherulites can be clearly seen on its epidermis, which is full of magnetism and distinct layers. There is a clear dividing line between the exposed part of the meteorite and the underground.

It can be seen that the characteristics of materials formed in different environments are different. Like the mother of the iron cow stone iron meteorite, the seemingly pure meteorite is actually a stone iron meteorite. Although iron in meteorites accounts for more than 90%, it still cannot change the original properties of meteorites. Under the golden molten shell, there is a red substance burning at high temperature. It is incredible that such a country still retains a strong magnetic force. This is a magical substance created by nature. In addition to containing all kinds of rare metal substances and organic substances, there are iron in the stone and stone in the iron, which are closely combined to form a special stone body. After 1000 years, it is still well preserved, without any corrosion or decay, which shows the unique material characteristics of Tieniu Stone Iron Meteorite!
