Few people in this world dislike granite. For the Chinese, there are many famous mountains in China, such as Mount Huangshan, Mount Jiuhua and Mount Tianzhu in Anhui, Mount Sanqing and Lushan Mountain in Jiangxi, Mount Taishan and Laoshan Mountain in Shandong, Hua Mountain and Mount Taibai in Shaanxi, Qianshan Mountain and Yiwulü Mountain in Liaoning, Hengshan Mountain in Hunan, Mount Putuo, Mount Mogan and Tiantai Mountain in Zhejiang, Keshiketeng Stone Forest in Inner Mongolia, Mount Taimu and Gulangyu in Fujian, Mount Luofu in Guangdong, Mount Gongga in Sichuan, Helan Mountains in Ningxia, Granite landforms can be seen in Wuzhi Mountain, Luhuitou, Tianya Haijiao, Xing’an Mountains and Qilian Mountains in Hainan. In human society, granite has become one of the most widely used indoor and outdoor building decoration materials due to its brilliant colors, stable chemical properties, and excellent physical and mechanical properties. Many magnificent domestic construction projects, such as the Great Hall of the People in Beijing, the National Grand Theater of China, Sun Yat-sen Mausoleum in Nanjing, the historical buildings on the Bund in Shanghai, the Luoyang Bridge and the East West Tower in Quanzhou, the the Potala Palace in Lhasa, and the German buildings in Qingdao, also have extremely rich granite elements. As an important Petrology symbol that distinguishes the Earth from other planets in the solar system, granite is like an art gallery of nature. No matter what kind of granite, it has amazing beauty.

If simply distinguished by patterns and colors, there are hundreds of types of granite products commonly used by humans in the world, which can be said to be very rich.
Common granite products have basically no colored stripes, only colorful spotted patterns. It is the uncanny craftsmanship of nature that creates all the forms of granite.

Billions of years ago, the Earth was formed by the fractionation, collapse and condensation of the original Solar Nebula. Each star child falling on the original earth has a high energy of motion, which is converted into heat energy due to impact. After that, the heat energy is preserved due to the increase of the earth’s external weight and the compression of the earth’s interior. In addition to the heat accumulation generated by the decay of Radioactive element, such as uranium, thorium, potassium, etc., the earth begins to become hot, causing the melting of most of the materials inside the earth.
Due to the fact that the crust of the primitive Earth was rich in iron, magnesium, and silicon, the initial melting only produced basaltic magma, which later formed the basaltic layer of marine landforms.
But when the basaltic rock undergoes melting again, the light matter with low density continuously rises and accumulates, gradually forming silicoaluminal magma, which is the granite layer mainly composed of silicoalumina that forms the landforms of continental regions.
As time went on, the preserved Continental crust was melted again and again, making its composition continue to increase in the direction of silicoalumina, while the residual Mafic returned to the mantle in an appropriate way.
This process is repeated, so that the Continental crust of the earth continues to develop in a stable direction, and finally forms today’s earth topography.

(The Earth’s interior is always in a molten state)

(Granite is distributed in the continental crust, basalt is distributed in the oceanic crust, and the density of granite is significantly lower than that of basalt)

It is precisely during the process of geological changes that the main elements such as silicon and aluminum are fully mixed by melting and the participation of water. After cooling, they form uniform porphyritic textures. Due to differences in the original composition of melts, cooling rate of magma, nucleation rate of crystals, pressure changes, amount of volatile substances, and fluid viscosity in different regions, various types of granite with different appearances have also been formed.
From the perspective of modern Mineralogy, we believe that granite is mainly composed of feldspar and quartz with silica and aluminum as the main elements, mica containing iron and magnesium, Amphibole, pyroxene, olivine, Serpentine subgroup, etc.
Among them, Orthoclase is usually gray white, yellowish brown and flesh red, plagioclase is usually gray white, quartz is usually transparent or gray, Biotite is usually black, brown, red and green, and pyroxene and Amphibole are usually black, dark green and dark brown. Generally speaking, the black, dark green and yellowish green granites contain more olivine, pyroxene, Amphibole, Biotite, etc., and almost no quartz and feldspar; The main components of white, flesh red, grayish red, light pink, gray, and grayish white granites are feldspar and quartz. Dark matter is more common in Biotite and less common in Amphibole.

It is worth noting that impurities mixed in the pores of rocks or the cleavage of minerals can also cause discoloration of the stone. Like Shijing Rust Stone, it is due to the weathering and decomposition of iron containing minerals that generate iron oxides and hydroxides that fill the pores and mineral cleavage of the rock, resulting in a rust yellow color of the rock.
In addition, when the crystal structure of minerals is defective, the color of granite may also change. For example, potassium feldspar is light flesh red and plagioclase is gray white. When the crystal structure is defective, potassium feldspar can be bright red and dark red (shiny Tieguan red, Yongding red, Huidong red), and Albite can be light blue (Puning big white flower).

When the chemical composition of minerals contains chromogenic ions, the color of rocks may also change. For example, when part of K in potassium feldspar is replaced by Rb, it will be Teal, which is the origin of Amazonite. The granite rich in Amazonite also has a unique flavor (such as Xinjiang Tianshan Blue).

Of course, with the continuous mining of granite stones produced by the same mine, there will also be certain differences in color between the surface granite and the deep granite. And using different processing techniques, the color of granite will also have slight differences, such as the color of the smooth surface always looks darker than the color of lychee or other rough surfaces.

Nature is always creating surprises and miracles for human beings. It may be such a piece of plain material. When the sawing machine cuts it open, it suddenly shows people the wonderful texture like Shan shui.
After thousands of years of sedimentation, nature endows natural stone with rich and colorful colors and ever-changing textures. No matter when, this magnificent creation created by nature is more spiritual than the works showcased by painters with thick ink.
I believe that when a stone that has been passed down for hundreds of millions of years encounters the craftsmanship of the new era, there will inevitably be a dazzling spark between the old and the new.
