Which pyroclastic phenomenon limits vegetation re-establishment following ignimbrite deposition?

💡 Explanation

Thermal alteration limits regrowth because ignimbrite's high temperature causes sterilization and vitrification, thereby hindering plant establishment; therefore, the alteration, rather than ash or oxidation, has a more prolonged impact.
