Magnesium isotope geochemistry has emerged as a pivotal tool in deciphering Earth’s surface and subsurface processes, particularly in the context of chemical weathering. By studying the subtle ...

Freeze-thaw weathering occurs when rocks are porous (contain holes) or permeable (allow water to pass through). Water enters cracks in the rock. When temperatures drop, the water freezes and expands ...

Rocks are not eternal. Even the tallest mountain will eventually dissolve and disintegrate. Geologists call this process “weathering.” It sounds harmless enough, but weathering is one of the most ...

Reactions between rocks, rain and carbon dioxide in the atmosphere have helped to stabilise the climate throughout Earth’s history, but they won’t prevent our carbon emissions from causing severe ...
