The formation process
The history of agate is very remote. About 100 million years ago, underground magma was spewed out in large quantities due to changes in the earth's crust. As the lava cooled, steam and other gases formed bubbles.The air bubbles are sealed up when the rock freezes and form many holes.After a long time, the holes were immersed in a solution containing silica and condensed to silica gel.The fusible components of the iron-bearing rock enter the silica gel, and finally the silica crystallizes into agate.
The world's famous agate producing areas are: China, India, Brazil, Madagascar, the United States, Egypt, Australia, Mexico and other countries.Mexico, the United States and Namibia also produce lace - like bands of agate, known as "lace agate".Scenic agate is also found in Yellowstone Park, Wyoming and Montana.China's agate producing area is also widely distributed, almost all provinces, famous producing areas are: Yunnan, Heilongjiang Xunke, Liaoning, Hebei, Xinjiang, Ningxia, Inner Mongolia and so on.
