Analysis reveals iron ore (Fe) concentrations in metallic minerals from Laeya, suggesting geological viability for extraction.
This study aims to assess the potential of metallic minerals, particularly iron ore (Fe), in the Laeya region, North Buton Regency, Southeast Sulawesi Province. The methods used include petrography, XRF, and magnetic susceptibility to analyze 16 samples collected from various research sites. Petrographic analysis reveals that the rocks in the Laeya area consist of wackestone, carbonate sandstone, and siltstone. XRF analysis indicates variations in iron (Fe) content in the rock samples, with the highest concentration reaching 7.15% in the siltstone. Magnetic susceptibility analysis supports this research, with the highest recorded susceptibility value of 414.5×10⁻⁸ m/kg. The geological structures identified include quartz veinlets and fault brecciation in the carbonate sandstone outcrops, which, along with indications of iron ore (Fe) mineralization, provide preliminary evidence of potential metallic mineral accumulation in the area.
