Is a meteorite natural glass What is a glass meteorite?

Not all of them, some are stone, some are metal, etc.

After a rainstorm, the beach often has some strange vitreous stones. They come in a variety of colors: black, dark brown, dark green, you name it.

They come in a variety of shapes: cakes, drops, dumbbells, buttons, and so on. They are concentrated in four major regions: China, Ivory Coast, the Czech Republic, and the United States, and are between 700,000 and 35 million years old.

However, the stones in the same area have a similar geological age and were produced in the same period. Their main components are 70 80 silicon dioxide and 4 calcium oxide. This is the famous "Lei Gongmo", which is called "Darwinian glass" in the West.

Regarding its life experience, countless Chinese and foreign scientists have been puzzled and hypotheses have been put forward.

In the theory of the earth, some believe that the lightning effect caused the rock to melt into a glass meteorite. But lightning is everywhere, so why are glass meteorites only distributed in a limited number of areas? Some believe that it was formed by volcanic eruptions.

However, volcanic eruptions occur randomly, which does not indicate the consistency of glass meteorites in time in the same area, and glass meteorites have not been found after some active volcanic eruptions. In extraterrestrial theory, some believe that the meteorite melted the rock when it hit the earth, but it does not indicate that the glass meteorite is only 40 million years old at most.

A more probable origin of "Lei Gongmo" is that at a distance of 145,240,000 kilometers from the surface of the sun, there are two elliptical rings of material, the composition of which is similar to that of quartz, and the temperature is about 1300. In 4 violent eruptions of the Sun, the material in the ring of matter was thrown into space, in which the solidified glass meteorite that fell to the Earth.

Meteorite is a stony, iron, or mixed material of stone and iron that has not been burned out of the original orbit of the cosmic meteor outside the earth or scattered quickly on the surface of the earth or other planets, also known as "meteorite". Most meteorites come from the asteroid belt between Mars and Jupiter, and a small number from the Moon and Mars. Meteorites can be broadly divided into; Stony meteorites, iron meteorites, mixed meteorites of stone and iron.

Each type of meteorite has its children underneath. Lunar meteorites can be divided into two categories: volcanic rocks and sedimentary rocks, lunar basalt is one of the main rocks that make up the moon, the color is black, white, dark purple, purple red, green, dark green, gray-green, yellow, brown-yellow, mixed colors, etc. The structure of the patchy structure and the structure of the almond are accompanied by biotite.

Common sulfides found in lunar meteorites are meteorite iron, pyrite, chalcopyrite, cristobalite and sulfur nickelite, and unknown minerals. The transparent molten crust on the surface of the lunar meteorite, which is a volcanic rock, is formed by the melting of the transparent material in the lunar rock at high temperature. Other melting phenomena such as:

The edges and corners formed by molten shells, melt flow lines, grooves, melt pits, and directional falls are very obvious. The transparent molten crust of lunar meteorites is a sign of lunar meteorites. Lunar igneous meteorites that have been severely eroded by wind have increased the likelihood of losing their transparent molten crust due to falling to Earth for too long, and this phenomenon usually does not affect the final identification of lunar meteorites.

Granular and massive clustered double-crystal aggregate plagioclase and microban molten breccia are commonly found in lunar meteorites. The colors are, colorless, white, dark gray, flesh red, pink, yellow, light yellow, green, transparent to translucent with glass luster. Tabular or flat columnar single crystals are often white, and needle-like olivine can be seen in tabular single crystals.

Lunar meteorites have the characteristics of breccia plagioclase, which is an important scientific basis for confirming lunar meteorites. Meteorites were previously considered a paranormal phenomenon.

No, it depends on the composition, some are Si, some are Fe, some are some compounds, and some are mixtures or something.

No, some contain iron.

Glass meteorite is a kind of stony meteorite, it is a natural silica-rich glass containing rare mineral inclusions, because of its appearance like obsidian, so it is also called obsidian. However, the composition and structure of the two are different. In ancient China, it was called Lei Gongmo.

According to legend, when the dark clouds rolled, Lei Gong accidentally dropped the ink block of writing the thunder order in the Qionglei area when he made lightning and thunder to run, so the southern tip of the Leizhou Peninsula and Hainan Island in China every time after the thunderstorm, there were some small stones with different colors and inks in the ravine, and the broken ones were like glass, hence the name. In the Tang Dynasty, Liu Sui's book "Ridge Table Record Difference" once recorded: "After the shower in Leizhou, people get stones like pam stones in the wilderness, which is called Lei Gongmo, and the buckle is solemn, bright and lovely."

Lei Gongmo generally weighs a few grams to one or twenty grams, and the heaviest one has more than 100 grams. There are droplet-shaped, spherical, thin tubular shape, flat plate-shaped, dumbbell-shaped, droplet-shaped, button-shaped, cake-shaped, tile-shaped, etc., but thick crushed walnut shell-shaped, irregular and flake-like are the most common. Interestingly, regardless of their size or shape, most of their sections resemble those of a wing, and are streamlined.

Therefore, it is most reasonable to speculate that it flew at high speed in a molten state before landing. The surface of Lei Gongmo has pits and lines. The pits are mostly long groove type with smooth at both ends, more than 10 mm long, and a few mm wide and less than 1mm wide and deep; The lines are convex and thick, sometimes parallel to the long axis of the vitreous, sometimes swirling, and sometimes scattered along the central tip of the button-shaped vitreous.

After several hours of corrosion with hydrofluoric acid, it can be seen that the pits are made up of densely packed smaller pits. It can be inferred that Lei Gongmo was formed under the condition of rapid melting at high temperatures and then sharp cooling.

Lei Gongmo is often black or dark green, translucent, and fragile, and has many shell-like fractures after rupture. Glass meteorites found on land are dim under reflected light, with only thin edges translucent, and their color varies from yellow to green, or from olive brown to dark brown. The density is generally , and the refractive index is.

Although its composition varies greatly with the falling region, the Si O2 content is very high, close to 100%. Microglass meteorites are found only in marine sediments, are less than a few millimeters in size, and have a similar age, composition and shape to those found on nearby continents.

There are different theories about the origin of glass meteorites, and some scholars believe that when a huge meteorite or comet hits the earth, the surface rock of the earth melts and splashes out of the crater at high speed and cools rapidly. There is also an opinion that glass meteorites are glass rains that fall from cosmic space into the Earth's atmosphere; Some scholars believe that glass meteorites are formed by vitrious cosmic fragments that burn violently when they enter the atmosphere and condense rapidly due to a sudden drop in temperature after falling to the ground.

First of all, it can be confirmed that this stone is not a meteorite, let alone a glass meteorite.

This is a stalactite, a limestone with a viscous mineral that has been eroded from above the cave for hundreds of millions of years and deposited.

Hello, glad for your question. A glass meteorite is a natural glass substance. Because of its appearance like obsidian, it is also called obsidian.

A glass meteorite is a huge meteorite or comet core that hits the earth, causing the earth's surface rock to melt and splash out of the crater at high speed and cool rapidly. It is also believed that glass meteorites are a rain of glass that falls from space into the Earth's atmosphere. As for the cause of glass meteorites, there is still no unanimous opinion.

Summary. Hello dear, <>

I'm glad to answer for you that glass meteorites really exist, glass meteorites are real. It is mainly a natural glass that quickly condenses after the melting of the target material on the surface when the extraterrestrial object violently hits the earth, with weak magnetism, and the color is dark green, green, light green, brown, brown, dark brown, and rare cinnabar.

Do glass meteorites really exist.

Hello dear, <>

I'm glad to answer for you that glass meteorites really exist, glass meteorites are real. It is mainly a natural glass that quickly condenses after the melting of the target material on the surface when the object hits the earth violently through the extraterrestrial ridge cluster, with weak magnetism, and the color is pure green, green, light green, brown, brown, dark brown, and the rare cinnabar color.

Hello dear, <>

The extension for you is as follows: "Meteorites have radiation: but the radiation is not strong, and generally nothing happens to the human body.

1. Before it falls to Earth, the meteorite will travel in space and will be exposed to solar cosmic rays and galactic cosmic rays, which will form some cosmogenic megalead nuclides. The half-lives of these cosmogenic nucleus elements are as short as milliseconds.

Thank you very much for your question. Glass meteorites are a rare type of meteorite whose main component is a glassy substance, usually formed by the melting of meteorites due to friction and high temperatures as they enter the Earth's atmosphere at high speeds. Glass meteorites vary in shape and color, some appear green, brown, black, etc., while others appear transparent or translucent.

The existence of glass meteorites was confirmed by scientists, and they fell from the sky to Earth. The number of glass meteorites is comparatively small as they make up only a small fraction of all meteorites. However, they are of great importance for scientific research because they can provide important information about the formation and evolution of the solar system.

In short, glass meteorites are hand-contained, and although there are not many of them, they are of great significance for scientific research.
