The formation of agate is a product of geological changes

Agate since it is not from the horses mouth spat out, that in the end is how did this happen? Ancient China gives a bizarre answer - "one that goes like this: horse brain who is the evil words of blood, cemented in this matter. Xi-Chi You and Huangdi In addition to the Quartet Qun Xiong, and various demon Charm, fill River Man Valley, the plot of blood into the yuan, poly bone, such as Yue. a few years, blood clotting, such as stone, bone white, such as gray, cream flow into the spring.

In fact, the formation of agate is a product of geological changes. Underground magma movements in the earth's crust due to a large number of emitting surface, and then cooling the formation of lava, silica-rich hydrothermal associated condensed into silica gel, along the rock wall of empty or void of weeks gradually filling to the center to form a concentric layer or parallel-layered block, and the gradual crystallization in the process, so the formation of ring-band structure of the agate. Agate is generally translucent to opaque, the hardness is about 6.5 ~ 7, accounting for 2.55 ~ 2.91, refractive index of 1.535 ~ 1.539. In the geological history of the various strata, both igneous rocks (also known as igneous rocks) or the formation of sedimentary rock can be agate. Therefore, the agate occurrence is very broad, structure and fineness was different.

Agate in the world well-known origin are India, Brazil, the United States, Egypt, Australia, Mexico and other countries. Mexico, the United States and Namibia also produced a lace-like pattern with agate, known as "lace agate." Yellowstone National Park, Wyoming, and Montana has also produced a "Moonstone." China's Heilongjiang, Liaoning, Inner Mongolia, Pearl pendant Hubei and other provinces have agate Pearl necklace output, but is located in western Liaoning Province, Fuxin output of agate known as the greatest. Fuxin is a major agate producing, processing and distribution center for land and onyx products, where resource-rich agate, agate and fine texture, color colorful, texture magnificent, crystal clear, is a good art carved wood. Moreover, Liao Xi Manao development and utilization of a very long history - about 8,000 years old, after Liao and Qing 2 boom, which the reign of Emperor Qianlong of the most flourishing. Here the water bile agate, red agate and green agate are very famous.
