What is the volcanic pipe?

volcanic pipe is a channel bored through the Earth's crust, which allows melted material from the magmatic chamber deep below the surface to travel up and out during the volcanic eruption. The input for the magma into the pipe is called an opening that ends in depression called a crater. Lava, ashes and ashes pour and explode from the pipes and the crater to form a mountain building or flat leaves of volcanic rocks-called cones or shields. Special types of inactive volcanic pipes are sought for being rich in diamonds.

Volcanic tube could go for centuries without any lava activity. Others are regularly active, because of the edges of tectonic plates that rubbed together and cause the pressures of molten rocks in underground magmatic chambers. The pipes could also see more effect if the tectonic boards are stretched, causing the magma from the deep in the ground to rise to the surface.

The magmatic chamber, just below the volcanic tube, usually forms on the Earth's crust. Is powered by molten mateRial just below it from the upper and lower cloaks. Several events can cause eruptions such as earthquakes, gaseous pressure in the magmatic chamber or the inflow of magma from tectonic activity. The chances of calamitous eruption increases because the amount of gas or liquid that mixes in the molten rock increases.

Although most volcanoes are formed in a label, cinder or giant composed volcanoes such as Mt. Fuji in Japan, another rare type is actually called a volcanic tube. These prehistoric pipes carry diamonds, carbon rocks called kimberlite or lamproit from deep inside the ground, through magma, to the level where the rocks cool. It takes 1,000,000,000 to 3,000,000,000 years to create a diamond.

The main hole of the volcano can also result in the main volcanic pipes and secondary pipes. These pipes create small secondary cones like bumps on a larger volcanic mountain. Once these pipes areFor many years, they have erode and allow diamonds to explore.

African nations such as South Africa, Angola, Botswana, Zimbabwe and Tanzania can boast the most diamond mines than on any other continent. The United States and Canada are not behind, while Canada has been digging diamonds in six active mines since 2012. Other nations such as Australia, India and Russia also contain a handful down that have been bringing these rare gems since 2012.
