“…Literature study was conducted on previous studies that examined limestone, especially the quality and utilisation of limestone as cement raw material. Field data collection began by taking rock samples at several points where limestone outcrops were found and based on colour differences (Thamsi et al, 2022;Thamsi et al, 2023). In addition to sampling, observations were also made of the geological conditions around the research area, and descriptions (megascopic analysis) of rock samples to obtain information in the form of rock position, direction of rock distribution, outcrop coordinates, and mineral content of rocks megascopically (Wakila et al, 2022).…”

Morowali Regency, Central Sulawesi Province is one of the largest nickel laterite producing areas in the world, on the other hand this area also has abundant limestone potential, one of the areas that has limestone potential is the Tangofa Area, Morowali Regency. The absence of information related to the chemical composition of limestone in the area is the basis for this research. The purpose of this study was to determine the elemental and mineral content of limestone and to determine the quality of limestone as cement raw material based on CaO and MgO content. The research method was carried out with several stages, namely: literature study, field data collection, and laboratory analysis (Petrography, XRD, and XRF). From the results of petrographic analysis, it can be seen that the constituent minerals of limestone in the research area are calcite and quartz minerals, as well as the results of XRD analysis, which show the presence of calcite minerals that dominate the entire sample with a percentage reaching 100%. The results of analysis with the XRF method can be known oxide compounds constituent limestone in the study area are: CaO, MgO, K2O, PbO, Nb2O5, CuO, Sb2O3, RuO4, SnO2, and In2O3. Rh2O3, TiO2, PdO, and Ag2O. The CaO content of the three samples has a percentage of >48%, while the average MgO content does not exceed 6%, so it can be concluded that the limestone in the study area has good quality for cement raw materials.

“…Tahap selanjutnya yaitu analisis sampel batuan menggunakan metode mineragrafi dan XRD analisis mineragrafi dilakukan untuk menentukan mineral yang terkandung dalam sampel dengan menggunakan mikroskop polarisasi. Mikroskop polarisasi juga dapat mengidentifikasi tekstur mineral melalui sayatan tipis dari sampel batuan [8]. Analisis mineragrafi ini dilakukan di Laboratorium Geokimia dan Mineral, Program Studi Teknik Geologi, Universitas Hasanuddin.…”

Sekitar 92% konsumsi mangan secara global berkaitan langsung dengan industri baja dan sisanya digunakan dalam aplikasi nir besi seperti baterei sel kering, bahan pewarna dan industri kimia lainnya. Provinsi Sulawesi Selatan memiliki potensi sumberdaya mangan yang tersebar di beberapa Daerah, Namun belum ditemukan penelitian tentang potensi mangan di Kab. Bone, Provinsi Sulawesi Selatan, yang mana di Desa Tebba, Kec. Salomekko, Kab. Bone ditemukan singkapan batuan pembawa mangan. Penelitian ini bertujuan untuk mengetahui mineral bijih dan asosiasi, menentukan tekstur dan paragenesis dari endapan mangan. Metode penelitian yang dilakukan yaitu pengambilan sampel, analisis Mineragrafi dan Mineral bijih yang ditemukan yaitu Pyrochorite, Pyrolusit, dan Rhodocrosite. Untuk mineral asosiasi yang ditemukan yaitu: kuarsa, albit, aragonit, klorit, arsenopirit, dan kalkopirit. Tekstur endapan mangan yaitu, tekstur Replacement dan Intergrowt. Paragenesis endapan mangan yaitu Pyrolusit tahap 1 Intergrowt tahap 2 Intergrowt. Rhodonite tahap 1 tidak ada, tahap 2 Replacement. Rhodochrosite tahap 1 Intergrowt, tahap 2 Replacement.
