Graphite stabilizes carbon in Earth's crust
Graphite could play an important role in sequestering carbon dioxide in the Earth's crust over geological time scales. So say researchers in the US and France who have calculated that graphitization, which occurs when mountain ranges form, produces a very stable form of carbon that is trapped in rocks and sediments for tens to hundreds of millions of years. The finding will be important for long-term modelling of the Earth's climate.
