Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and long-lasting weathering of the underlying parent rock. Definition and physical.
It forms in tropical and subtropical regions where the climate is humid. However, not all laterites are enriched in iron and sometimes they are not even reddish. Some lateritic rocks (bauxite) are mined . Laterite is a reddish weathering product of basalt. Found mainly in hot, wet tropical areas, it develops by intensive and long-lasting weathering of the underlying parent rock. Informations on laterites , bauxites and lateritic ores.
