Which process causes increased clay mineral formation when plinthite underlies a waterlogged region?

💡 Explanation

Plinthite leads to increased anaerobic bacterial iron reduction because the fluctuations in the water table drives redox reactions in iron and other compounds, therefore promoting anaerobic reactions rather than aerobic, which would limit iron oxide concentration.
