Which mechanism causes timber to petrify into stone-like material over geological timescales?

💡 Explanation

When silica-rich water permeates wood, silica precipitation within the cell structure occurs because dissolved silica replaces the organic material, creating a stone-like fossil. Therefore silica precipitation results, rather than carbonization, fungal degradation, or oxidation, which require different chemical environments and processes.
