Science finds the stone

An extremely popular stone on the East and West coasts called Peridotite may be the savior of humanity in the future, when the Earth is getting hotter due to CO2 causing the greenhouse effect.

When viewed under a polarizing microscope, you will see that it has an extremely beautiful color.

An extremely popular stone on the East and West coasts known as Peridotite may be the savior of humanity in the future, when the Earth is getting hotter due to CO 2 causing a greenhouse effect. "Someday, they could be an extremely useful tool to combat global warming ," said Sam Krevor, head of a new study at Columbia University's Earth Institute.

White streaks are layers of minerals containing CO 2 formed when water has dissolved CO 2 flowing through the stone.

How will those rocks save the Earth? Scientists have long known that stone absorbs dissolved CO 2 in water by connecting CO 2 to minerals to form solids like calcium carbonate, a very common substance in rock and a component. main in shells, eggshells.

Now, scientists have been able to accelerate this process millions of times in laboratory conditions by crushing stones and adding sodium citrate catalyst. After being crushed, these stones recover after only a few minutes by absorbing CO 2 from the surrounding air. However, more research is still needed before it can be applied widely.

This type of stone is abundant in Oman.

In addition to the US East and West coasts, the rocks are also very popular in Oman , the islands of Papua New Guinea, along the Adriatic coast and many other parts of the world because it is the most popular rock in the Earth's crust. . Sam Krevor estimates that the amount of rock in the US alone can absorb the amount of carbon dioxide that the US emits in 500 years. "The problem is not the number of stones, but making them work .
