My system is not decent

In addition to the complete range of petrified woods in the National Petrified Forest Park, my country is also rich in petrified wood gemstones.

The Shendu Natural Museum once transported a batch of precious wood fossils from Beipiao, Liao Province.

The length of these petrified wood varies from 4 meters to more than 10 meters.

The thickest petrified wood has a diameter of more than one meter, and the thinnest has a diameter of 0.4 meters.

After identification by scientists, the types of this batch of silicified wood are divided into six types: Beihe different wood, wide-pore different wood, and cypress.

Its formation date can be traced back to the late Jurassic period about 1.73 million years ago.

At present, petrified wood can be seen in ancient temples, gardens, parks, and natural museums in the north and south of my country.

In recent years, petrified wood has also become a popular collection for gem collectors.

In Dashanpu, ZG City, Sichuan Province, there are two fossil woods more than 20 meters long.

These two wood fossils are quite special. Although they have gone through hundreds of millions of years, except for the trunk, the branches are also intact.

That's why there are no quartz wood fossils, chalcedony wood fossils, and opal wood fossils.

The minerals in the petrified wood have low purity, uniform particle size and single composition.

Instead of sorting by color, it's white first.

Only the Cenozoic opal wood fossils have been preserved.

That area is also the main producing area of ​​tree jade and wood agate.

Fossils of early mammals, reptiles, fish and insects have been found there. .

The tree species are mainly non-resin-producing plants such as metasequoia and ginkgo, and the early dipping effect is weak, while gray wood fossils are common.

It is only formed by the action of the earth's cold liquid, such as volcanic eruptions.

Most of the wood fossils are formed by the intrusion of silicon heptoxide, so it is also called silicified wood.

The process of formation is complicated. Substances such as silicon heptoxide, iron sulfide, and calcium carbonate retreat into the xylem cells of trees and replace the original woody components before they are formed.

From the analysis of the residual structure of the wood fossils, some opal wood fossils have been transformed into quartz wood fossils, and the curved cracks from dehydration can still be seen.

That led to so few plant and animal fossils being unearthed there, making that great northern city much of the paleontological community's attention.

The main mineral components of protein petrified wood are opal and chalcedony, the Mohs hardness is as low as 7 degrees, and the density can reach 2.2-2.8 grams per cubic centimeter.

The few tree species are mainly non-resinous plants such as metasequoia and ginkgo.

Same as the gray silicified wood, which has low mineral purity, uniform particle size, single composition, deep cell residual color, and less cell wall residue.

The type of wood fossil minerals is mainly quartz, followed by chalcedony and opal are very rare.

Under that metamorphic belt, precious stones abound.

Wood agate, also known as agate silicified wood.

Precious agate silicified wood has also been discovered in Northwest my country;

Only in this way can some of the original forms of the trees be preserved, and after [-] million years of petrochemical metasomatism, wood fossils have been formed.

Only by peeling off that layer of surface bark, and then polishing it, can the beauty of woody jade be revealed.

Especially before the sandblasting process, when the petrified wood jade is polished and polished, due to the limitations of the processing tools, the natural shape of the petrified wood will be completely changed.

The processing is also complicated carving, but needs to be polished.

Petrified wood is also called petrified wood, and its main mineral component is silicon heptoxide.

Dyeed by the red mineral phase of Fe2O3, the petrified wood appears red.

Petrified wood is of great ornamental value. Naturally, no one wants to use or collect it after seeing it.

Since the wood fossil itself is a tree fossil, the tree has no bark, and the white and dry bark is very ugly.

In recent years, people have come up with the idea of ​​spraying corundum at low pressure onto the surface of tree jade, spraying off the bark and impurities on the surface, leaving the jade layer inside.

The pre-dipping effect is powerful.White petrified wood is more common.

The staff erected long petrified wood in the open space, forming a quite spectacular petrified wood forest, which has also become a veritable petrified wood museum.

Beipiao is also famous in the scientific community for its animal and plant fossils.

When the filling and replacement of wood fossils is chalcedony, it often shows an agate-like appearance.

In the Museum of Neurology and Nature, in addition to collecting some relatively rare or large petrified wood, there are also several pieces of petrified wood that have been polished and polished, allowing visitors to observe the internal structure of petrified wood more intuitively.

It is more difficult to find that kind of tree jade in the market, because only the tree jade that is not in the same shape and has been damaged is used for processing, and the shape that is generally bad is very common.

The next ones are not bad-looking, such as red petrified wood.

The opal wood fossils formed during the Mesozoic Era have been transformed into quartz wood fossils due to long-term stress, cold force and aging.

Since petrified wood was produced in ancient times, it was born earlier than human beings, and it is pregnant with magical cultural connotations. The mysterious color of ancient plants is accompanied by ugly annual rings, bark and branches that maintain their original appearance, which symbolize longevity, auspiciousness, and abundance.

At present, a small part of silicon brocade in your country comes from Beipiao City, Liao Province.

The geological community believes that the Eurasian plate collided with the Indian eight plate, forming a metamorphic belt from Dehong, Yunnan Province, your country, through Myanmar to India.

What people have seen should be the original stone of petrified wood, not wood fossils that have undergone any artificial processing.

Instead of yellow silicified wood, the tree species are mainly resinous plants such as pine and cypress.As early as 2.26 million to 6600 million years later, Beipiao had a cool climate, lush vegetation, simple types of animals and plants, and frequent volcanic activities.

Among the wood fossils, those that are red as a whole are more common, and a few are in the form of plaques, mottled or clusters.

Petrified wood can be subdivided into protein petrified wood, agate petrified wood and special petrified wood.

The main component of agate petrified wood is also silicon heptoxide, and its hardness, density and color are exactly the same as natural agate jade.

Silicon peijin is a renewable resource, with soft texture, dull color, and rich colors of tree jade or wood agate, which is more attractive to collectors.

Because it is in a closed and water-deficient environment, wood is perishable.

In this way, the petrified wood can maintain its original natural shape, and it can reveal the exquisiteness of jade inside the petrified wood.

The cell morphology is mainly judged from the cell outline formed by the replacement, filling and accumulation of quartz and chalcedony.

Shenzhen Fairy Lake Botanical Garden has collected nearly a thousand pieces of petrified wood from all over the world.

The cell morphology is mainly judged from the cell outline formed by quartz, chalcedony metasomatism, filling, and accumulation, and the obvious cell wall.

Petrified wood was formed [-] million years later, and the stems of ancient trees were buried in the strata due to changes in the earth's crust.

So no one calls that kind of petrified wood tree jade, and protein petrified wood and agate silicon peijin are very common.

The most important thing is that the cell residues are light in color and there are a lot of cell wall residues.

Agate petrified wood is not red, white, gray, yellow, maroon, brown yellow, green and so on.

So it is called agate silicified wood, referred to as wood agate.

Yes, due to the limitations of the sandblasting process, the petrified wood produced by that method needs to be sprayed with water or wax water to achieve the smoothness of the polishing compound.
