Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged

  • Oolites, Pisolites and Laterites Formation and Composition

    Jun 27, 2017· Aluminous laterite (bauxite) is mostly composed of aluminum hydroxides gibbsite, diaspore, and boehmite. Not all bauxites are laterites, though. Some bauxite deposits are associated with limestones and karst phenomena. Lateritic bauxite is a weathering product of aluminous silicate rocks (granite and similar).Geochemical study of laterites of the Jamnagar district,The laterite deposits occur in a linear stretch along the northern Arabian Sea coast in the Jamnagar and Porbandar districts of, Gujarat state, India. These deposits are characterised by presence of gibbsite, kaoline, calcite, quartz, anatase, natroalunite, goethite and hematite, and relicts of mafic minerals and plagioclase.

Laterite descended from basalt is rich in iron and nickel and is termed ferruginous laterite. Laterite formed from rocks particularly rich in nickel may contain a high percentage of the mineral garnierite ([NiMg]6Si4O10[OH]8).
