Laterite - Wikipedia
网页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 Formation, Tropical Climates & Weathering
网页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. Lateritic soils may contain clay minerals; but they tend to be silica-poor,
Lateritic Soil - an overview | ScienceDirect Topics
网页Lateritic soils are abundant materials available around the tropical and sub-tropical areas in the world. However, due to their chemical and mineralogical complexity, their use in geopolymer synthesis remains limited.
Lateritic Deposits : Formation, Mineralogy, Ores - Geology Science
网页2023年11月18日 · Lateritic deposits are a type of weathering product that forms in tropical and subtropical regions through the process of laterization. Laterization involves the leaching of silica and other soluble materials from rocks, leaving behind a residual concentration of iron and aluminum oxides.

Laterite Soil - an overview | ScienceDirect Topics
网页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.
Laterites - SpringerLink
网页Laterites are products of humid tropical or subtropical weathering. Profiles developed under arid or semiarid climates, in which carbonates, salts, smectites or amorphous silica could be formed are excluded; so are profiles which retain easily hydrolysable primary minerals such as feldspars or amphiboles.
A state of review: challenges and techniques of laterite soil ...
网页2022年5月3日 · Laterisation (also known as tropical weathering) is the long-term chemical weathering process, which results in substantial differences in the chemical composition, thickness, grade, and ore mineralogy of the newly formed soils [5, 6]. In certain Asian countries, laterite has long been utilised as the main building material in construction.
