My system is not decent

Chapter 1910 Quality Color Shape Tattoo

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.

There are also several colors mixed, or regularly distributed.

Due to the strong silicification, the lignofibrous cell structure remains very little.

In some parts, ring-shaped annual rings and cell morphology can be seen. After polishing, it is delicate and smooth, and has a strong sense of jade.

These are mostly composed of quartz, chalcedony minerals, but resemble agate rather than agate.

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

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

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

During the secretion process, SiO2 gel slowly precipitates and crystallizes in the cavity.

Some have quartz crystal clusters growing on the wall of the central cavity.

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.

But as far as the whole trunk is concerned, it does not have the geological environment for the formation of agate.

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

At the junction of Yunnan, Guizhou and Sichuan provinces, nearly 50 square kilometers, there are Permian Emeishan basalts.

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

Most of the Yuhua stones are also agate. In the amethyst cluster caves that are abundant in Brazil, there are strips of agate distributed at the end of the wall.

The lignofibrous structure and even cell structure of petrified wood, as well as the trunk shape, bark, annual rings, wormholes and other characteristics are preserved.

Therefore, it can not only show wealth and beauty with its materials, but also show beauty with its fossil growth rings, bark, knots, wormholes, textures and other colorful features.

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

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

It can also be cut and honed to create petrified wood jewelry.

Such as beads, rings, pendants, bracelets, etc., the texture is fine and well-proportioned, can reflect the wood texture, or the cell structure is the best.

Wearing such jewelry can help you feel the life course of hundreds of millions of years on the earth, thereby enhancing your inspiration and confidence in understanding the mysteries of the earth;
Every ornament made with it reflects the life on earth for hundreds of millions of years and the infinite beauty of the world, so it has a story for collectors.

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

First of all, it is not easy to produce high-quality petrified wood realistically;

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

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

It is generally believed that the most valuable should be silicified wood with insect fossils.

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

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 is the best petrified wood.

Ordinary silicified wood is generally called tree fossils, and it is tree petrified jade, which is more beautiful.

There are many such fossils, and the larger the unit price, the higher the unit price. For a piece of several kilograms, the public price is 10 yuan per kilogram.

A piece weighs 15 kilograms and can be sold for up to 30 yuan per kilogram.

The most expensive is the tree jade, which means that the fossils form agate shape, and it feels like jade, so it is more expensive
Of course, even if it costs ten yuan a kilogram, sometimes petrified wood can be sold at a sky-high price.

Because the size of some petrified wood is very large.

For example, Fushun Yongnian petrified wood comes from Group 4 of Juyuan Village, Yongnian Town, Fushun County.

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

Including six large pieces of petrified wood scattered in crop fields or beside houses.

And a piece of silicified wood that is still buried in the rock formation, just passing under the village road, with a length of nearly ten meters.

You must know that this is a stone, such a large petrified wood that is as heavy as a stone, each weighs more than ten tons.

There is also a petrified wood fossil produced in Qitai, Xinjiang Province, with a length of 38 meters and a root diameter of 1.2 meters. It is an extremely rare giant fossil and the longest petrified wood in the world.

2.5 million years ago, there were dense forests on the earth, most of which turned into coal, and a very small part was exchanged with stable silicon oxide during the burial process, and petrified into silicified wood.

According to experts' speculation, if the tree is complete, it will be as high as 80 meters.

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

Therefore, Chen Wenzhe had a kind of windfall this time.

He wanted to learn woodcarving, and he also learned stone carving techniques before, and at the earliest there was a top-level jade carving technique.

All of this can be realized on petrified wood.

Because of petrified wood, you can call it jade, you can call it wood, and you can call it stone.

This kind of material is huge and easy to buy, which is simply an excellent carrier for him to contact technology.

As long as there are enough materials, Chen Wenzhe can quickly develop a unique skill.

If you use good materials in this way, you will definitely be able to get good works.

If there are still some petrified wood with peculiar shapes, maybe he can also produce some exquisite works like root carvings.
