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. |

Eruptive Event Caught Red-Handed Researchers know that, in general, mid-ocean ridges are the site of periodic eruptive events that create new seafloor. At the East Pacific Rise, determining the seismic characteristics that lead up to eruptions could help researchers predict when and where along the trench future events are likely to occur. |
