Resumen de Mars air turned to stone to cool planet
Tim Tomkinson and colleagues at the Scottish Universities Environmental Research in East Kilbride UK studied a Martian meteorite known as Lafayette, thought to have landed on Earth roughly 3,000 years ago. Using a scanning electron microscope they found veins of carbonate minerals. These form when carbon dissolved in water seeps into rocks containing the mineral olivine. The carbon replaces the olivine, locking it away.
