In the middle of the Devonian Period some 385 million years ago, the Wissahickon Schist was the heart of a huge mountain chain that was something like the Pacific Northwest of today. Volcanoes formed here and there. The land was subjected to earthquakes and eruptions from time to time. To the west was...

A geological controversy over how a 2,700-million-year-old rock was formed has been solved using synchrotron technology, an international team reports. A rare form of magmatic rock known as komatiite was formed in the Earth's mantle at temperatures around 1700 degrees Celcius in the Archaean a...
