Laterite is a soil type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content.
Laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions where the climate is humid.
Aug 4, 2017 · Laterite Soil. The word laterite has been derived from the Latin word ‘Later’ which means brick. These soils when wet are as soft as butter but become hard and cloddy on drying. Therefore, these are widely cut as bricks for use in house construction.
Laterite is a reddish or yellowish soil formed at the surface or near-surface of the earth in tropical (Africa) and sub-tropical (Australia and South America) zones of the world.
Laterite soil is formed by weathering rocks in tropical regions with heavy rainfall. The process involves breaking parent rocks rich in iron and aluminum over time. Rainwater carries away soluble minerals, leaving behind insoluble materials. The iron and aluminum compounds in the rocks oxidize, forming iron oxide and aluminum oxide.
Jan 23, 2016 · Distribution of Laterite – Lateritic Soils. Laterite soils cover an area of 2.48 lakh sq km. Continuous stretch of laterite soil is found on the summits of Western Ghats at 1000 to 1500 m above mean sea level, Eastern Ghats, the Rajmahal Hills, Vindhyan, Satpuras and Malwa Plateau.
Nov 18, 2023 · Soil Formation: Laterites contribute to the formation of tropical soils. While they may not be suitable for agriculture due to their low nutrient content, they play a role in shaping the landscape and influencing ecosystems.
Dec 1, 2022 · Laterite soil is leached residue from the process of laterisation. • Geotechnical chemical and mineralogical characteristics of laterite soil were critically reviewed. • The influences of laterite soil on the performances of building/road products were discussed. •
Laterite soil is rich in aluminum and iron, formed in wet and hot tropical areas. Almost all laterites are rusty red due to the presence of iron oxides. It is prepared by the long-lasting and intensive weathering of the parent rock.
Sep 21, 2023 · Lateritic soils are highly weathered residual soils found in tropical and sub-tropical regions, formed as a product of the laterization of rock. The colour of lateritic soils ranges from dark reddish brown, through rusty red, to purple.
