This article by Scott P. Hippensteel of the University of North Carolina at Charlotte describes how carbonate rocks produced rolling terrain that limited the range and effectiveness of both artillery and small arms.

Geologists know that the early atmosphere contained carbon dioxide because carbonate rocks, formed when carbon dioxide reacts with minerals, were laid down at least 3.8 billion years ago.

The negative cycle means that it is stabilizing the temperature of Earth: because the carbonate reservoirs are vast, the effect is powerful; but because it takes hundreds of millions of years to transport carbonate rocks to subduction zones via plate tectonics, the cycle is also very small.

We acknowledge that the biggest obstacle to any explanation for warming early Mars with carbon dioxide is their ultimate fate: are there carbonate rocks buried underneath the martian regolith?

The Australian CO2 mineral carbonation research pilot plant will be established at the University of Newcastle to trial a new technology that transforms captured CO2 emissions into forms of carbonate rock for potential use as new green building materials in the construction industry.

Porosity formed by leaching in siliceous carbonate rocks gives the reservoir low permeablity, but relatively homogeneous composition for miscible displacement.

The following lava streams entered carbonate rocks and coal beds, from which they in turn released enormous amounts of CO2, perhaps equivalent to 3 trillion tonnes of pure carbon, or some 11 gigatonnes of CO2, a 2010 Nature Geoscience study estimates, quite suddenly switching the world from cooling to heating.

The firestorms would have produce an enormous injection of CO2 as well as soot, and the impact crater in partially calcium carbonate rock would have produced direct CO2 from the reduction of that rock, but neither the «nuclear winter» not the subsequent global warming extinguished life.
