Question

List the minerals found in alluvial soil ?​

Answer 1

Answer:

Alluvium consists of silt, sand, clay, and gravel and often contains a good deal of organic matter. It therefore yields very fertile soils such as those of the deltas of the Mississippi, the Nile, the Ganges and Brahmaputra, and the Huang rivers.

Answer 2

Sand and silt fractions are dominated by primary quartz. Other minerals present in these fractions include muscovite, plagioclase and alkali feldspars, amphibole, biotite, and chlorite. Illite, chlorite, and kaolinite have been identified in the clay fraction of each soil with smectite being present in one soil.
