| Summary: | Rare Earth Elements (REE) are elements from the lanthanide group+Sc+Y that
currently play a critical role in several modern technological industries. Due to
their scarcity, the number of exploration for REEs has been increasing, and
therefore, this research was conducted as a preliminary study aiming to identify
clay minerals from weathered granitoids as carriers of ion adsorption-type REEs
in the Mamasa Regency, West Sulawesi, using petrographic analysis, X-ray
diffraction (XRD), Reflectance Spectroscopy, and Scanning Electron Microscopy
Energy Dispersive X-Ray Spectrometry (SEM-EDS). Petrographic analysis reveals
that the parent rock in Pebassian Mamasa Village, is granodiorite, and the
minerals suspected to carry REEs are zircon and monazite. Clay minerals such as
kaolinite, halloysite, montmorillonite, saponite, and illite were identified as
potential clay minerals capable of binding REEs. The occurrence of REEs in the
Mamasa Regency, West Sulawesi, indicates that REEs are carried by clay minerals
belonging to the kaolinite, smectite, and illite groups, due to the ability of these clay
minerals to adsorb REE ions on their surfaces. |
