Which soil mineral change accelerates desert pavement formation?

💡 Explanation

Desert pavement requires fine particles removal; enhanced eluviation (leaching) selectively removes clay, because this leaves larger rocks behind and creates a stable surface. Therefore enhanced eluviation is the answer, rather than oxidation/frost which breaks down rock but not removes the resulted material.
