How is agate formed

The formation of agate is mostly from the outbreak of volcanoes hundreds of millions of years ago. Both volcanic rocks and sedimentary rocks can form agate. How does agate form?
1. Due to the outbreak of the volcano of the crustal movement hundreds of millions of years ago, the hot basalt pulp quickly rushed out of the ground to encounter cold bubbles with different sizes and different shapes. After the volcano stopped eruption, the magma formed rocks.The siliconic acid solution inside the volcano or the inside of the volcano is affected by the pressure of the siliconic acid solution. The fissure of the rock rock is covered with empty cave. With the cooling of the magma, the precipitation crystals of the year, and the minerals containing iron, manganese, cobalt and other mineralsThe comprehensive reflection forms agate.
2. Due to the crustal movement, the magma flow rises, how the agate is formed when it rises to a certain height, and the water fluid will dissolve with the underground water.Formed air bubbles, these bubbles are different, sparsely sparse, and different shapes. As the magma rises again, the pressure of the earth is reduced, the rock flowing bubble becomes larger and swept the rolling. When the magma reaches a certain height, it is no longer flowing.
3. Bubbles are also positioned with positioning. At this time, the shape of the bubbles will no longer change. With the cooling of temperature, the outermost layer of silicon dioxide gradually forms a split, opaque, dense and hard agate thin shell., Cool oxide gone, cooled again, the silicide gel forms a chalcedony, distributed on the inner wall of the shell. At this time, the agate containing light particles in the gas mixture appears black strips, and the brown band containing manganese oxide.The appearance of light or light gray strips containing calcium and magnesium. These pigment ions containing pigment ions are crystals according to different temperatures.Go out and be closed in the empty cave in agate and deform into water gall agate.
The formation of agate is the formation of agate. Because the division of thermolo magma is different from the external environment, the structure after formation is also different. There are layers of bands, homogeneous, hollow, and solid.
The above is provided by Xiaobian for you. I hope you will like it.
