Cataclysm at Meteor Crater: Crystal sheds light on Earth, moon, Mars
Madison WI (SPX) Jul 28, 2016
In molten sandstone extracted by prospectors a century ago, an international team of scientists has discovered microscopic crystals telling of unimaginable pressures and temperatures when a 12-kilometer asteroid formed Meteor Crater in northern Arizona some 49,000 years ago. The crystals, called zircons, have endured temperatures of 2,000 degrees Celsius or more, hot enough to melt any rock on Earth. In our planet's crust, such temperatures occur only briefly inside impact zones, says Aaron Cavosi ... read more
