China News Service, Hefei, April 6th (Reporter Wu Lan) "Based on our systematic research, we have put forward a new point of view-the nickel-containing aerosol produced by the eruption of the Great Igneous Province of Siberia is an important factor in the mass extinction of life at the end of the Permian.
At the end of the Permian period, about 250 million years ago, the largest extinction event occurred on Earth, causing the disappearance of more than 90% of life in the ocean and more than 70% on land.
“The Great Igneous Rock Province refers to igneous rocks with an area of more than 100,000 square kilometers, and the Siberian Igneous Rock Province covers an area of more than 1 million square kilometers.
The research team believes that the eruption of the Great Siberian Igneous Province formed a large amount of nickel-containing aerosols, which were transported by the global atmospheric circulation to sink to the ocean and land.
The study not only proves the important role of nickel in changing the marine and terrestrial environment, but also builds a bridge between the eruption of the Great Igneous Province of Siberia and global environmental changes.
