Due to their unique chemical, magnetic, and luminescent properties, rare earth elements (REE) are necessary for high-tech enterprises. Ion Adsorbed Deposits (IADs) and Ion Adsorption Clays (IACs) are types of REE deposits formed by chemical weathering of REE-rich parent minerals. This study investigated soil profiles associated with the weathering of Late Triassic granitic bodies in the South Perak region of Peninsular Malaysia in order to advance our knowledge of the behaviour and distribution of rare earth elements during granite weathering.
Surface and subsurface samples were collected from eight sites. For laboratory analysis, the samples were dried, pulverised, sieved, and ground to the desired mesh size. In South Perak, there are vast exposures of granitic igneous bodies, and Ion Adsorbed Clays (IACs) contain sufficient concentrations of Rare Earth Elements (REEs) associated with this form of weathered rare earth deposits. At numerous locations, the total REEs content (TREE) exceeds the minimum threshold value of 300 ppm.
