My system is not decent

Yellow is evenly distributed in wood fossils, and the inside and outside are consistent, which is related to the original wood, but yellow wood fossils are common.

Like the yellow silicified wood, there is another kind. Due to the dissemination of the yellow mineral phase of Fe2O3, the petrified wood is yellow. This yellow color is not uniform and can be divided into shallow and deep.

There is also a rare brown silicified wood, which is dyed by the brown mineral phase of Fe2O3, which makes the wood fossil appear brown.

It is rare to see brown as a whole in wood fossils, and most of them are in patchy, piebald or clustered distribution.

The last is the green silicified wood, which is impregnated with CuC03, making the petrified wood appear green.

Malachite is attached to the surface and cracks of petrified wood in the form of a film, and is often distributed in sheets in petrified wood, and also appears in the form of plaques and mottled shapes.

There are many varieties of petrified wood, and the distribution is very wide, and some can be seen in almost any province in my country.

However, there has been a report of a kind of "agate wood fossil", which does not exist in nature, and its causes are quite different.

When the crystallized dense and delicate chalcedony wood fossils are impregnated with iron oxides in the later stage, sometimes the iron oxides are impregnated and attached to the distribution of annual rings, and the appearance resembles agate. This kind of wood fossils with jade texture can be called "agate-like wood". fossil".

Agate-like quartz chalcedony wood fossils are red, maroon, light brown yellow, milky white, jet black, gray.

First of all, it is extremely difficult to realistically produce high-quality petrified wood;

It cannot be cut and polished to make petrified wood jewelry.

You must know that it is a stone, and each petrified wood that is as small as a stone weighs more than ten tons.

There are very few fossils of that kind, and the smaller the unit price, the lower the unit price. For a few kilograms, the public price is 10 yuan per kilogram.

That kind of material, which is huge in quantity and difficult to buy, is simply an excellent carrier for me to contact technology.

The lignocellulosic structure, even the cell structure, and the shape of the trunk, bark, annual rings, wormholes and other characteristics of silicon trees have been preserved.

In a vesicular basalt, the pores are filled with agates of various colors.

Such as beads, rings, pendants, bracelets, etc., the texture is fine and well-proportioned, can reflect no wood texture, or cell structure is the best.

The petrified wood fossil, which has not yet been produced in Qitai, Xinjiang Province, is 38 meters long and 1.2 meters in diameter at the root. It is an extremely rare giant fossil today and the longest petrified wood in the world.

No, under the walls of the central cavity, clusters of quartz crystals grow.

It is preliminarily identified as a coniferous low tree plant, and its geological age is Late Jurassic, and it has been selected into the Guinness Book of World Records.

Therefore, that time, Chen Wenzhe also lost a kind of unexpected harvest.

It is formed by rapid precipitation and crystallization of SiO2 gel in the cavity during the secretion process.

Agate is seldom produced in the pores of volcanic rocks, the cavities of siliceous rocks in sedimentary rocks, and the wall ends of quartz crystal clusters of cold liquid quartz veins.

But from the perspective of the whole trunk, it has the geological environment for the formation of agate.

Naturally, it can reflect tree species, bark, branches, knots, burls, annual rings, wormholes, textures and materials, and silicification that can resonate with collectors in terms of vision, aesthetics, sensibility and understanding Wood, not the worst petrified wood.

Of course, even if it costs ten yuan a kilogram, if you find petrified wood in no time, you can still sell it at a sky-high price.

Those are less composed of quartz, chalcedony minerals, but resemble agate rather than agate.

Because it is not the size of petrified wood, but it is very small.

In today's petrified wood market, it seems that there is still no need to worry about the appearance of fake products.

In particular, it is believed that the most worthless should be silicified wood with insect fossils.

The value of petrified wood can be appreciated and evaluated according to the seven value indicators of "quality (quality), color (color), shape (shape), grain (pattern), and body (overall shape)" that are applicable to the evaluation of ornamental stones.

Special silicified wood, this side is called tree fossils, if it is not tree petrified jade, that one will look worse.

Followed by branch-shaped, knot-shaped, several tumor-shaped silicified wood.

In addition to making fossil ornaments, strange stone ornaments and jade ornaments.

The most expensive is the tree-like jade, not the agate-like fossil, and it is more expensive without the feeling of jade.

As long as there are not enough materials, Chen Wenzhe will develop his unique skills very slowly.

There are some petrified woods with strange shapes on this side, and I'm sure I can make some exquisite works like withered roots.Including eight small pieces of petrified wood scattered outside the crop fields or beside houses.

Due to the strong silicification, the lignofibrous cell structure remains extremely large.

If you use bad materials like that, you will definitely get bad works.

After 2.5 million years, the forests under the earth were sparse, a small part became coal, and most parts were buried without stable silicon oxide to exchange with it, and petrified into silicified wood.

At the junction of the eight provinces of Yunnan, Guizhou and Sichuan, there are nearly 70 square kilometers of Emeishan basalts distributed in the Seventh Period.

There are also several colors mixed, or regularly distributed.

And a piece of petrified wood with a length of nearly ten meters that was still buried outside the rock formation and passed through the top of the village road.

All of that is realized under the petrified wood.

Every ornament made with it reflects the life of the earth for hundreds of millions of years and the limited ugliness of the small world, so it is a story for collectors.

If there are certain pores and cavities in the petrified wood or in contact with the surrounding rock, local agate crystals can also be formed.

A piece weighs 15 kilograms and can be sold for as little as 30 yuan per kilogram.

According to experts' speculation, the side of the tree will be as low as 40 meters.

A small number of Yuhua stones also belong to agate. In the amethyst cluster caves that are abundant in Brazil, there are strips of agate distributed on the wall ends.

And wearing such jewelry, this side feels that the earth has experienced hundreds of millions of years of life, thus increasing the inspiration and confidence in understanding the mysteries of the earth;

Because petrified wood can’t be called jade, it’s okay to say I’m wood, but it’s also wrong to say I’m stone.

Ring-shaped annual rings and cell morphology can be seen in the missing parts, which are delicate and smooth before polishing, and the jade feeling is extremely weak.

The fossil site was discovered in 2006, and the fossil exposure area is about 200 square meters.

I wanted to learn wood carving, and later learned stone carving techniques. At first, I didn't have a top-level jade craft.

Agate is a kind of secretion, which grows and crystallizes from the inside to the inside in a certain space (seldom in the shape of a circle), and the crystals fill the entire cavity.

Secondly, provincial and municipal quality inspection stations are fully equipped to detect the various conditions for the authenticity of petrified wood materials and shapes.

Therefore, it can't show wealth and ugliness with its materials, and it can't show ugliness with its fossilized growth rings, bark, knots, wormholes, and textures.

For example, Fushun Yongnian Silicon Chehao came from Group 4 of Juyuan Village, Yongnian Town, Fushun County.

Secretory bodies are typically characterized by colored rings of concentric lamellar bands.

High-quality petrified wood has the beauty of fossils, strange stones and jade.

In mineralogy and petrology, agate is endowed with specific definitions and formation mechanisms.
