Radioactive Elements in New Mexican Rock Reveal Longest Earthquake Record
White calcite deposits in rocks from a fault line in New Mexico helped scientists create a record-long earthquake record. Photo by Laurel Goodwin and Randy Williams Using radioactive elements trapped in crystallized, cream-colored “veins” in New Mexican rock, geologists have … Continue reading
New Form of Carbon That’s Hard as a Rock, Yet Elastic, Like Rubber
Visualization of ultrastrong, hard and elastic compressed glassy carbon. A team including several Carnegie scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could … Continue reading

Earth science: Rock samples indicate water is key ingredient for crust formation
By examining the cooling rate of rocks that formed more than 10 miles beneath the Earth’s surface, scientists have found that water probably penetrates deep into the crust and upper mantle at mid-ocean spreading zones, the places where new crust … Continue reading
