In the United Kingdom, the variable bedrock geology and long-legacy of anthropogenic land use provide challenges to isolating carbonate and silicate mineral weathering, meaning the we lack constraint on an important flux in the UK’s carbon cycle. Here the authors use river chemistry data collected over 40 years for 52 catchments across the UK and apply a geochemical inversion model (MEANDIR) to assess the silicate and carbonate contributions to UK river chemistry, and to estimate the CO₂ consumption from natural weathering.
