New findings on reverse weathering speed For decades, scientists believed reverse weathering was too slow to influence any environmental change on shorter time scales. However, these new studies ...

Crushed volcanic rock spread on farms accelerates natural carbon capture processes. This method converts atmospheric carbon ...

A tractor spreads crushed white rock on a green hill, leaving a plume of dust in its wake. Scientists believe that enhanced ...

The natural rock weathering process, while effective in breaking down carbon and storing it within rocks over thousands of years, may not provide the immediate solution to combat climate change. With ...

Overview figure of the weathering continuum, in which processes from the highest mountain to the deep ocean play a role in removing CO2 from the air. Credit: Gerrit Trapp-Müller et al. A new study has ...

Geochemical weathering in mineral deposits encompasses the breakdown of primary rock‐forming minerals, the mobilisation and fixation of liberated elements, and the development of secondary mineral ...

Weathering modifies rock fabric through chemical alteration and physical disintegration, driving changes in pore structure, fracture density and mineral assemblage. Chemical reactions between water, ...

During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the Ordovician ...
