Boehmite occurs in tropical laterites and bauxites developed on alumino-silicate bedrock. Recent deposits are alluvial soils, high and low level laterites, and ferruginous conglomerates. It consists of peninsular gneiss, granites, basic dykes and laterites. The ground water laterites are developed over shale and granite. About 60% is in laterites and 40% in sulfide deposits. For high-magnesium silicates in lower profiles laterites the exploitation method used is smelting. He carried on with his work in laterites and widened his interest to calcarcous rocks. The mineralogical and chemical compositions of laterites are dependent on their parent rocks. Nickel laterites are generally mined via open cut mining methods. The Cabook Aquifer laterites support relatively shallow aquifers that are accessible to dug wells. Generally nickel laterites require very large olivine-bearing ultramafic intrusions. Nickel laterites are a very important type of nickel ore deposit. Although soils like laterites are typical example of Zonal soil found in the area. The bulk of these deposits are now laterites. Approximately 60% is in laterites and 40% is in sulfide deposits.
