In fact, only two eruptions were larger than the one in the Pacific Northwest: the basalt flood of the Siberian Traps
and the Deccan Traps.
A devastating confluence of geological events is thought to have triggered the Great Dying a quarter-billion years ago, including a massive eruption of climate-changing carbon dioxide from volcanoes associated with the Siberian Traps
The Siberian Traps
eruptions spewed more than 3 million cubic kilometers of molten rock (SN: 1/15/11, p.
They found volcanism related to the formation of the Siberian Traps
likely injected two pulses of carbon dioxide into the atmosphere during the Permian-Triassic Boundary extinction, which lasted about 60,000 years.
Some researchers have suggested that these gases might have been spewed out by the volcanic eruptions that produced the Siberian traps
, a vast formation of volcanic rock produced by the most extensive eruptions in Earth's geological record.
Up to 90% of marine species and 70% of land vertebrates were killed by massive volcanic eruptions from the region now called the Siberian Traps
, which covers much of northern Asia.
The explosion created the Siberian Traps
, huge deposits of igneous rocks in what is now Russia.
It is believed to have been caused by volcanic eruptions in Russia which produced a huge area of lava known as the Siberian traps
An even larger lava field, the Siberian Traps
, covers the Noril'sk-Putarana Plateau in north central Siberia.
They are hosted in a number of intrusions that were part of a network of feeders to the Siberian Traps
Other recent research has suggested that in this volcanic area called the Siberian Traps
, the intense heat of (http://www.
To determine whether eruptions from the Siberian Traps
triggered a massive increase in oceanic carbon dioxide, Burgess and Bowring are using similar dating techniques to establish a timescale for the Permian period's volcanic eruptions that are estimated to have covered over five million cubic kilometers.
