(9 years ago)Geologists have come up with a new thesis that the largest mass extinction of species on Earth was caused by strong magma pulses that caused deadly greenhouse gas levels to be released in the atmosphere.

In an article in the scientific journal Nature Communications, a group of scientists suggests that the powerful volcanic eruption, 252 million years ago, has destroyed more than 95 percent of marine species and 70 percent of land species.
The end of the Persian period corresponds to rapid changes, namely. A show of volcanic activity in Sibyri.
In the region known as the Siberian trap, large quantities of magma have circulated across the Earth. Rather than explode, they were scattered through the earth's crust, creating a wide network of rocks that span more than a million square miles [1 million sq km]. Magma is then solidified between the old layers of the Sedimentary rocks, in the geological formations known as “the threshold”.
The extreme heat from these <x0). Chemical tracks of ancient rocks show that in the period of mass extinction, temperatures have increased by 8-10 degrees. It is supposed to have burned large quantities of coal, carbonate, and rock, for which reason the atmosphere has sent in large quantities of greenhouse gases, such as methane, carbon dioxide, and sulfur dioxide, which have caused the end of Perma's geology period, broadcast Telegragraphy.
Michael Benton, professor of spinal paleontology at the University of Bristol, said: “This job is important because of the match with the volcanic blast phase with the disappearance of the species”.
The Siberian Kurt exploded for a million years or more, but the peak of extinction has occurred in 50,000 years or less. This corresponds to the episode of the design of angels when the magma entered the oldest layers of sedimentary rocks around the site of the explosion. It is very important that this coincides with the maximum levels of carbon dioxide production, which led to extreme global warming”, Benton added.
Massive extinctions are usually blamed on volcanic eruptions, but these studies have confirmed that lava explosions on the surface of the earth occurred earlier to enable them to know the causes.
Russia's Siberian Korans, for this research, studied Seth Burgess geologist at the state-owned USS Geological Survey; Samuel Bowing Professor of geology at MIT; and James Muirhead fellow researchers at the Department of Science for Earth.
