The Siberian Traps were a massive lava flow that is believed to be responsible for one of the earth's mass extinction events (see map below). The time of the lava flow has been dated using the K-40/Ar-40 method. The half life of K-40 is 1.3 x 10⁹ years. Norway Sweden Finland Russia Kazakhstan. Arctic Ocean Extent of the Siberian Traps Russia China Bening Sea Japan Mongolia A sample of rock from the lava flow was found to contain 6.152 x 108 K-40 atoms and 8.756 x 107 Ar-40 atoms. How long ago did the lava solidify?
