The minerals in the soil are classified into two categories, namely\tPrimary Minerals in soil: These are minerals which have not been chemically altered since deposition. They are same or similar to their parent materials. Often these materials are bigger in size and irregular in shape. These primary minerals are usually found in sand and silt.\tSecondary Minerals in soil: These are minerals formed as a result of weathering of Primary Minerals. Secondary minerals are mainly found in fine silt or clay. The particle size of these minerals is much smaller, due to the weathering process. These minerals have a large surface area that helps them retain moisture.
