Australian scientists say that they have found the oldest volcanic chimney in the world, which is more than 1.25 billion years ago.
Pilbara Pilbara Pilbara's meteorite in Australia's Pilbara area, ahead of 3.5 billion years, while the famous volcanic crater was only 2.2 billion years old. The team's research results are Published Today in natural communication

The outstanding stone that helps the researchers indicate that the crater is called the rich, and they will form in a violent environment caused by the effects of meteorite. Space rocks affect the current area known as Damamart Poland, about 25 miles of Pilbara (40 kilometers) in Western Bar in Western Australia. The most well -known crater is currently in Western Australia in Yarrabba.
From the launch of a meteorite that causes the crater (100 km), which is larger than 62 miles (100 km) hit the world more than 22,370 miles per hour (36,000 kilometers per hour).
The cone gives the “clear evidence” of the high -speed meteorite impact of 3.47 billion years ago. The writing team and the age of the impact are all around the world.
“The disclosure of this effect and more search at the same time can be explained a lot about the beginning of life because the meteorite hole created environmentally friendly, microbes such as hot water,” Chris Kirgland, geologist.
Of course, some of the world The oldest evidence for life Found in the area of the meteorite impact Stromatolites – Concrete, microbes found in shallow hot waters outside the coast of Australia – Almost Age 3.5 billion years– stromatolites Propose an indication of what the fossils of life on Mars have. Last year, the researchers announced the discovery of The oldest knows Synthesis of fossils, which go back to 1.75 billion years and can be found in Australia.
“In addition, our understanding of the formation of the formation of the earth's crust is severe: enormous energy. From this effect, it may play a role in the creation of the earth's crust of the world by pushing part of the Earth's crust under another part of the surface,” Kirgland added. Previous evidence from Pilbara – Hin, the oldest crust in the world – states that Earth It may be used on earth between 3 and 4 billion years ago. When the effect of this Stagmage meteorite occurred
