Silicified wood: Also known as wood fossil, the main mineral component is silica. Silicified wood was formed hundreds of millions of years ago, and the stems of ancient trees were buried in the strata due to changes in the earth's crust. Wood is not easy to decay because it is in a closed, water-deficient environment. After the action of the earth's hydrothermal fluid (such as volcanic eruptions), substances such as silica, iron sulfide, and calcium carbonate enter the xylem cells of the tree, replacing the original wood components and retaining some of the original forms of the trees. After more than 100 million years of petrochemical exchange, the formation of wood fossils. Most of the wood fossils are formed by the intrusion of silica, so it is also called silicified wood. Silicified wood can be subdivided into protein silicified wood, agate silicified wood and ordinary silicified wood. The main mineral components of protein silicified wood are opal and chalcedony. The Mohs hardness is up to 7 degrees and the density can reach 2.2---2.8 g/cm3, so some people call it silicified wood. Both protein silicified wood and agate silicified wood are rare. Wood agate: also known as agate silicified wood. The main component of agate silicified wood is also silica. Its hardness, density and color are exactly the same as natural agate jade, so it is called agate silicified wood, referred to as agate. The geological community believes that the Eurasian plate collides with the Indian plate to form a metamorphic belt from Yunnan Dehong in China through Myanmar to India. In this metamorphic belt, gemstones are produced. This area is also the main producing area of ​​tree jade and wooden agate. Agate silicified wood has red, white, gray, yellow, maroon, brownish yellow, green, and the like. Silicified wood is of great ornamental value: since silicified wood is produced in ancient times, it is born before human beings, and it is bred with magical cultural connotations. The mysterious color of ancient plants is accompanied by beautiful annual rings, keeping the original bark and branches, which symbolizes Longevity, good fortune, and richness. Silicified wood is a non-renewable resource. The hard, brightly coloured, colorful wooded jade or wooden agate is more attractive to collectors. In addition, as verified by geologists, there is no scientific basis for radioactivity. Silicified wood does not contain any radioactive elements. How to collect when you buy home? The precautions are: 1. Keep away from high temperatures and avoid direct sunlight. 2. Common vegetable oil is applied to the surface to keep the surface smooth. 3. Avoid rubbing against other high hardness items to avoid scratches on the surface.
