These are derived from two types of parent materials: Alluvium, loess and windblown sand. Most alluvium is geologically Quaternary in age and is often referred to as "cover" because these sediments obscure the underlying bedrock. Because floods periodically deposit new sediment at the surface, alluvial soils can have a unique layered look. Pedogeochemical survey is also known as soil survey. The next time you are on a floodplain remember that unique alluvial soils that form there provide many beneficial values to society: agricultural production, pollutant trapping, and preserving evidence of our own human history. After alluvial soil, red soil are 2nd largest areal soil types in India.

When this loose alluvial material is deposited or cemented into a lithological unit, or lithified, it is called an alluvial deposit. You’ll find them along rivers, in floodplains and deltas (like the Mississippi Delta), stream terraces, and areas called alluvial fans. In other cases, flood deposition can also bring contamination from upland pollution.

Alluvial soils may represent important sinks of contaminants as a result of the deposition of contaminated sediments along the river by overbank flooding or after dredging. Alluvium (from the Latin alluvius, from alluere, "to wash against") is loose, unconsolidated (not cemented together into a solid rock) soil or sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Examples could be deforestation, plowing for agriculture, or disturbance during construction activities. The soil is the unconsolidated weathering product. Dark and light colors alternate, along with assorted sizes of round gravel particles. They vary in color from reddish brown in north to red or gray in south.

Volcanic Volcanic soil, particularly basalt, is an extrusive soil formed from cooled, hardened, and weathered lava. Soil Taxonomy- principal reference to soil classification. Dry Alluvial Soils-these soils have been decomposed by the process of mechanical weather­ing. Igneous soils can be either intrusive or extrusive, made from the cooling and solidification of magma or lava from within or without the Earth’s crust. Bajadas are common in dry climates, such as the canyons of the American Southwest. This soil is well-drained and poorly drained with an immature profile in undulating areas.

These human activities can increase erosion of uplands, and the resulting sediment then flows downriver and is deposited. Silt, which is known to have much smaller particles compared to sandy soil and is made up of rock and other mineral particles, which are smaller than sand and larger than clay. They showed that the insoluble fraction of an Eocene limestone from west of Kermanshah and the Asmari dolomite in west of Khorramabad, Luristan, are rich in palygorskite.
