Which mineral enrichment results when desert deflation lowers elevation?

A)Relative concentration of heavy minerals
B)Increased precipitation of carbonate minerals
C)Greater oxidation of iron compounds
D)Decreased cation exchange capacity

💡 Explanation

Heavy minerals accumulate because selective particle removal via deflation leaves larger dense materials; therefore, heavy minerals increasingly compose surface lag deposits, rather than smaller grains enriched by leaching or chemical weathering processes.
