Summary
We incorporate in this chapter kinetic rate laws into reactive transport models to show how water–rock interaction leads to chemical weathering. We consider as examples rainwater infiltrating an orthoquartzite aquifer and the percolation of rainwater through a mineralogically complex soil, accounting for biogenic production of carbon dioxide.
