← GeographyWhich process leads to copper deposit concentration within alluvial fans?
A)Selective sediment deposition sorting✓
B)Enhanced evaporative mineral precipitation
C)Oxidation increasing mineral solubility
D)Transform fault induced mineralization
💡 Explanation
Selective sediment deposition sorts minerals by density during alluvial fan formation, therefore concentrating heavier copper deposits in specific zones, rather than other mineral enrichment processes; differing densities are key.
