Rockstock - about this paper made from stone.

Calcium carbonate accounts for more than 4% of the Earth's crust. As a result, the three calcium carbonate minerals - calcite, aragonite and vaterite - are among the most important rock-forming minerals. And rocks are not the only calcium carbonate deposits in nature.
