Truth, Fiction and Everything in Between at Yellowstone The Yellowstone caldera is a volcano, and it almost certainly will erupt again someday. It's possible, though unlikely, that future eruptions could reach the magnitude of Yellowstone's three largest explosive eruptions, 2.1 million, 1.3 million and 640,000 years ago. |

Zircons reveal mantle evolution A team of Finnish geologists has discovered 3.1 billion-year-old zircons in the Jormua ophiolite of eastern Finland. Although not the oldest zircons on Earth, the Jormua zircons are the oldest yet found in mantle rocks. Their discovery has given scientists a brief glimpse into the history of early plate tectonics. |
