The analytical methods used are X-ray Fluorescence (XRF), X-ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Scanning Electronic Microscopic (SEM). The result of the research showed that the chemical composition of Angus stone consists of silicone mineral and iron. The kind of silicone mineral is identified as mineral quartz, cristobalite, and tridymite while the iron mineral is identified as maghemite. The silicone mineral morphology has tetragonal, cubic, orthorhombic, hexagonal, and trigonal geometry shapes. ## Keywords - Tridymite - Mineral - Cristobalite - Mineralogy - Quartz - Chemical composition - Fourier transform infrared spectroscopy - Cinnabar - Orthorhombic crystal system - Geology - Morphology (biology) - Materials science - Hematite - Chemistry - Crystallography - Metallurgy - Chemical engineering - Crystal structure - Engineering - Organic chemistry - Paleontology --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
