What is the reason for the white crystals in volcanic eggs

The white crystals in the volcanic eggs are columnar crystals formed by the condensation of unexposed magma ejected during volcanic eruptions. These white crystals are a special mineral in volcanic stones, called "columnar joints". The formation of this mineral is due to the cooling and solidification of minerals in magma under high temperature and pressure.

During the cooling process, the water and gases in the minerals are expelled to form a porous, lightweight, acid-resistant special material, known as volcanic stone. Because volcanic stone contains a large number of minerals and trace elements, it is believed to have certain nutritional value and health care effects.

The columnar crystals formed by the condensation of unexposed magma ejected during volcanic eruptions are called "columnar joints" in geology. Tengchong County, known as the "Volcano Geology Museum", has more than 70 volcanic sites, located in Qushi Township, this "joint", an area of about square kilometers, formed 10,000 years ago, is the largest, well-preserved, shortest columnar joint found in China so far.

In the vicinity of the crater, you can also pick up volcanic stones in gray, red, and black as souvenirs. Along the way, there are also souvenirs made by local villagers from volcanic stones, including various zodiac signs, flower pots, ashtrays, volcanic eggs, etc. This volcanic stone has a very light specific gravity and is called "pumice".

A person can gently lift a large piece and throw it into the water without sinking. The natural law of what people call "sinking into the sea" does not work here.

Whether it's a treasure or not depends on what you like. Speculation: It may be a silica crystal with more copper elements.

If there are stripes, there is a high chance that it will be agate, what color.

The composition is quartz SiO2, and the holes are crystalline small crystals. This one belongs to the wax stone with a very poor texture.

When a volcano erupts, the volcanic ash that is spewed out condenses into ,,。

What's the point of doing this? I guess it is melted at high temperatures, taking advantage of the properties of crystalline and amorphous.

Hello, it must be the material of agate.

Tubular agate is very appropriate, first to show you a piece of information for reference.

Protobotanist William Walton Wright made a special visit to one of the origins to study and identify the geological environment in which tubular agate was formed. He believes that the main cause of tubular agate is that when a volcano erupts, a cascade of siliceous ash rushes like a cascade into a swamp or hillside and then into a wetland. Volcanic ash is weathered and oxidized to release abundant silicon, iron, manganese and other ions into the water.

Those decomposed water undergo chemical changes that increase the acidity of the clay and suspend colloids.

As the plant dies and decays, and some stems continue to stand or bend, some stems may be "broken" and fall into the swamp. The stalks of these swamp plants can become the core of cryptocrystalline quartz (agate) deposition after crystallization. Under the influence of rain and dry weather, the swampy waters rise and fall, causing its acidity to change.

Repeated eruptions and ash deposition can lead to the formation of agate crystals around layers of stems and other marsh bottom debris.

The causes of various types of agate are very complex and can not be blindly dogmatic, and agate is a kind of jade that can be associated, usually associated with the crystal group (typically crystal) jade and silicified jade, nature has a lot of mysterious and unverifiable places, such as the origin of jade may be a special kind of special cause, to say a definite and convincing result is to go through rigorous research, can not rashly draw conclusions, so as not to mislead, of course, it also gives us the interesting space for speculation, This is also the original charm of jade.
