Smart Stones: THE rate of olivine weathering, an expensive myth

"In this note I provide some data on the weathering of olivine in nature, which make clear that the weathering of olivine is fast enough to play an important role in the cycle of CO2 capture and its safe and sustainable storage as carbonate rocks. The CO2 released by volcanism has always been captured by the weathering of rocks since the origin of the Earth. Without this mechanism the Earth would be a lifeless planet with a CO2 atmosphere in the order of 100 bar, as our neighbor planet Venus demonstrates."
