Abstract
This study investigates the petrogeochemistry of potential rare earth element (REE) weathered granitoids from Gua Musang, Kelantan, with a focus on understanding their soil profiling, mineralogical and geochemical characteristics. The research aims to evaluate the concentration and distribution of REEs within the weathered profiles of these granitoids, employing methods such as petrographic analysis, X-ray diffraction (XRD), X-ray fluorescence (XRF), and inductively coupled plasma mass spectrometry (ICP-MS). The results indicate a significant variation in the REE content across different weathering horizons. The parent rock predominantly comprises quartz, feldspar, and mica, with secondary minerals such as kaolinite and nacrite appearing in the weathered zones. Geochemical analysis reveals that the REEs are primarily concentrated in the clay fraction, with light rare earth elements (LREEs) being more abundant than heavy rare earth elements (HREEs). The data suggest that the weathering process enhances the mobility and enrichment of REEs, particularly in the upper soil horizons. This study provides valuable insights into the mineralogical and geochemical behavior of REEs in tropical weathered granitoid environments, contributing to the understanding of REE exploration and extraction processes in similar geological settings. The findings also highlight the potential of Gua Musang as a significant source of REEs, which could support future resource development strategies in Malaysia.
