Critical Zone Processes Limit Alkalinity Export from Natural Basaltic Systems

August 27, 2026Pablo Navarro1 мин

New observations from volcanic watersheds reveal a significant attenuation of alkalinity fluxes. These changes occur along the entire reactive pathways, from the soil layer all the way to the river. This process leads to a reduction in the amount of alkalinity that is exported, highlighting the limiting role played by processes within the critical zone.
