The yellow color is evenly distributed in petrified wood, consistent inside and outside, and is related to the original wood, except that yellow petrified wood is common.
For example, there is yellow petrified wood, and there is another kind. Due to the dyeing effect of the yellow mineral phase of Fe2O3, the petrified wood appears yellow. This yellow color is uneven and can be divided into shallow and deep.
There is also a rare kind of brown silicified wood, which is dyed by the brown mineral phase of Fe2O3, making the petrified wood appear brown.
Among petrified wood, the overall brown color is rare, and most of them are distributed in patches, mottled shapes or clusters.
Finally, there is the green petrified wood, which is dyed by CuC03, making the petrified wood appear green.
Malachite adheres to the surface and cracks of petrified wood in the form of a film. It is often distributed in sheets in petrified wood, and also appears in patches or mottled shapes.
There are many varieties of petrified wood and their distribution is very wide. You can see some in almost every province in my country.
However, there have been reports of a kind of "fossilized agate wood", which does not exist in nature and has a very different origin.
When the crystallized and fine-grained chalcedony wood fossils are disseminated by late-stage iron oxides, sometimes the iron oxide dissipation is attached to the growth rings, and the appearance resembles agate. This kind of jade-like petrified wood can be called "agate-like wood".
fossil".
Agate-like quartz chalcedony wood fossils are available in red, maroon, light brown, milky white, jet black, and gray.
First of all, it is extremely difficult to make high-quality petrified wood realistically;
It cannot be cut or polished to make petrified wood jewelry.
You must know that they are stones. Petrified wood that is as small as a stone weighs more than ten tons each.
There are very few fossils of that kind, and the smaller they are, the lower the unit price is. For pieces of several kilograms, the public price is 10 yuan per kilogram.
That kind of material, in huge quantities and difficult to purchase, is simply a perfect vehicle for me to connect with technology.
The wood fiber structure, even the cell structure, and the inner shape of the trunk, bark, growth rings, wormholes and other features of the silicon car are preserved.
In a kind of pore-like basalt, the fillings in the pores are agates of various colors.
Such as beads, rings, pendants, bracelets, etc., those with a fine and well-proportioned texture that can reflect no wood texture or cell structure are the best.
The petrified wood fossil, which has not yet been produced in Qitai, Xinjiang Province, is 38 meters long and has a root diameter of 1.2 meters. It is an extremely rare giant fossil today and the longest petrified wood in the world.
Under the wall of the central cavity, quartz crystal clusters grow.
It was initially identified as a coniferous low tree plant with a geological age of the Late Jurassic. It has been selected into the Guinness Book of World Records.
Therefore, Chen Wenzhe had no unexpected gains that time.
During the secretion process, SiO2 gel rapidly precipitates and crystallizes in the cavities.
Agate is rarely produced in the pores of volcanic rocks, in the cavities of siliceous rocks in sedimentary rocks, and on the wall ends of quartz crystal clusters in cold liquid quartz veins.
But from the perspective of the entire tree trunk, it has the geological environment for the formation of agate.
Natural, it can reflect the types of trees, bark, branches, knots, burrs, growth rings, wormholes, textures and materials, and can have a visual, aesthetic, perceptual and intellectual resonance for the collector.
Wood, not the worst petrified wood.
Of course, even if it costs ten yuan per kilogram, if petrified wood is discovered by chance, it can still be sold at a sky-high price.
Those are rarely composed of quartz and chalcedony minerals, but are shaped like agate rather than agate.
Because the size of the petrified wood is very small.
In today's petrified wood market, it seems that there are still worries about the emergence of fake products.
In particular, I think the least valuable thing is the petrified wood with insect fossils.
The value of petrified wood can be appreciated and evaluated based on the seven value indicators applicable to the evaluation of ornamental stones: "quality (quality), color (color), shape (shape), grain (pattern), and body (overall shape)".
The special petrified wood, this side is called tree petrified wood. If it is not tree jade, it looks worse.
Followed by dendritic, knot-shaped, and knob-shaped petrified wood.
In addition to making fossil ornaments, strange stone ornaments and jade ornaments.
What is more expensive is tree-turned jade, which is not fossilized into agate shape. It does not have the feeling of jade, so it is more expensive.
As long as there are not enough materials, Chen Wenzhe will slowly develop a unique skill in this area.
There are still some strange-shaped petrified wood here, and I am sure I can also come up with some ingenious and unique works that look like withered roots. These include eight small pieces of petrified wood scattered outside the crop fields or next to private houses.
Due to the strong silicification, a lot of the wood fiber cell structure remains.
If you use bad materials like that, you will definitely get bad works.
250 million years later, the forests under the earth were sparse, and a small part turned into coal. During the burial process, most parts were not exchanged with stable silicon oxide, and petrified into petrified wood.
At the junction of the eight provinces of Yunnan, Guizhou and Sichuan, under an area of nearly 700,000 square kilometers, the Emeishan basalt of the Seventh Period is distributed.
There are also several colors mixed or regularly distributed.
And a piece of petrified wood that is still buried outside the rock formation and passes over the village road, nearly ten meters long.
All of that is realized under the petrified wood.
Every ornament made with it reflects hundreds of millions of years of life on earth and the limited ugliness of the small world, so for collectors, each piece has no story.
If there are certain pores and cavities in petrified wood or in contact with surrounding rocks, local agate crystals may also be formed.
A piece weighing 15 kilograms can be sold for as low as 30 yuan per kilogram.
According to expert speculation, this side of the tree would be as low as 40 meters.
A small number of Yuhua stones are also agates. In the amethyst cluster caves that are abundant in Brazil, there are strips of agates distributed at the ends of the walls.
Wearing such jewelry allows one to realize that the earth has experienced hundreds of millions of years of life, thus increasing the inspiration and confidence to understand the mysteries of the earth;
Because petrified wood cannot be said to be jade, it is fine to say that it is wood, but it is also wrong to say that it is stone.
In the missing parts, ring-shaped growth rings and cell shapes can be seen. They are delicate and smooth before polishing, and have a very weak jade feel.
This fossil spot was discovered in 2006, and the fossil exposure area is about 200 square meters.
I wanted to learn wood carving, and later I also learned stone carving techniques. At first, I didn’t even have top-notch jade carving techniques.
Agate is a secretion body that grows and crystallizes from the inside out in a certain space (usually round), and the crystals fill the entire cavity.
Secondly, provincial and municipal quality inspection stations are fully equipped to detect the authenticity of petrified wood material and shape.
Therefore, it cannot show wealth and ugliness with its material, nor can it show ugliness with its fossilized growth rings, bark, knots, wormholes, texture and other colorful features.
For example, Fushun Yongnian Silicon Car Hao comes from Group 4 of Juyuan Village, Yongnian Town, Fushun County.
Secretory bodies are typically characterized by a color ring with concentric lamellar bands.
High-quality petrified wood combines the beauty of fossils, strange stones and jade.
Agate has a specific definition and formation mechanism in mineralogy and petrology.
