The formation of jadeite rough is a complex and lengthy geological process that involves a variety of geological processes and mineralogical principles.
1. Magmatism and the initial formation of jadeite rough.
The formation of jadeite begins in the depths of the earth, in the mantle, about 300,400 kilometers above the surface. At this depth, there are rocks rich in sodium and aluminum, which undergo a series of chemical changes under high temperature and high pressure. During this process, some silicate minerals containing elements such as magnesium, iron, and chromium begin to form and gradually crystallize into jadeite minerals.
This process can be likened to the synthesis of gemstones in the laboratory under high temperature and high pressure conditions. Just as we put some chemicals in a high-temperature and high-pressure environment, they undergo a chemical reaction and crystallize into new minerals, the rocks deep in the earth are undergoing a similar process under natural conditions.
2. Regional metamorphism and the further evolution of jadeite rough.
As the earth's crust moves, these initial jadeite minerals are lifted to the near surface. During this process, the rock undergoes intense pressure and temperature changes, which causes the minerals in the rock to recrystallize to form larger and purer jadeite mineral crystals. This process is similar to how we make candy by controlling the temperature and humidity to form different crystalline forms.
At this stage, the color of the jadeite mineral also begins to change. As different trace elements enter the crystal structure of jadeite minerals, jadeite exhibits different colors. For example, the presence of iron causes jadeite to take on a green color, which is what we commonly refer to as "emerald green."
3. The metasomatization and the final formation of the jadeite rough.
When surface water infiltrates these jadeite minerals, it reacts with some of these elements. This metasomatism changes the structure of jadeite minerals, further increasing its purity and crystallinity. This process is similar to when we make ceramics, by controlling the composition of the glaze and the firing conditions to obtain different colors of porcelain.
At this stage, the basic characteristics of the jadeite rough begin to emerge. Its color is more vibrant, the texture is more delicate, and the luster is warmer. At the same time, due to the influence of metasomatism, some other mineral inclusions or cracks began to appear in the jadeite rough.
Fourth, the geological characteristics and identification of jadeite rough.
Jadeite rough has the following characteristics in geology: AI assistant creation season
Color: Jadeite comes in a variety of colors, but green is the most common and valuable. The green color can range from pale green to dark green, and is often accompanied by white, black, or red streaks or spots.
Texture: The texture of jadeite is delicate and hard, and it feels heavy to the touch. Its luster is warm and soft, giving it a sense of nobility and elegance.
Structure: Observing under strong light or magnifying glass, you can see the structural characteristics inside the jadeite, such as fibrous and granular. These structural characteristics are due to the crystallization of jadeite minerals and the environment in which they are grown.
Hardness: The hardness of jadeite is higher and generally at 6Between 5 and 7. This gives it a certain durability in gemstones and is not easily scratched or damaged.
Density: The density of jadeite is generally 33~3.Between 4. This means that it weighs relatively large, which is also a way for us to check the authenticity of jadeite by hand when buying it.
Jadeite: This is an important feature of jadeite, which refers to the reflection of the cleavage surface of jadeite minerals that can be seen on the surface of jadeite, commonly known as "fly wings". This is due to the crystal structure of jadeite minerals, and it is also one of the important bases for distinguishing real and fake jadeite.
In summary, the formation of jadeite rough is a complex and long geological process, involving a variety of geological processes and mineralogical principles. Through an in-depth understanding of these principles, we can better appreciate and distinguish between real and fake jadeite, providing a strong guarantee for collection and investment.
