Rock can soak up Carbon Dioxide- Steph M

11 11 2008

Geologist Peter Kelemen and geochemist Juerg Matter have discovered that the rock peridotite can soak up carbon dioxide and convert it into solid materials such as calcite. This is the most common rock found in the Earth’s mantle but is only found in a couple places on the earth’s crust. It is found mostly in Oman but can also be found in Papua New Guinea, Caledonia, along the coast of the Adriatic Sea and in small amounts in California. Scientists say that the process can permanently store 2 billion of the 30 billion tons of carbon dioxide that are emitted from human activity each year.
