Analysis of Mineralization in The Galena Deposit at Baturappe Village, Gowa Regency, South Sulawesi Province
Main Article Content
Abstract
Galena deposits are a mineral resource of high economic value and play a crucial role as a source of lead (Pb) in various industries. Galena deposits have been discovered in Baturappe Village, Gowa Regency, South Sulawesi Province; however, there is currently no preliminary information regarding the prospects of these galena deposits in the area. The objectives of this study are to identify the ore minerals of the galena deposits and their associated minerals, to describe the texture of the galena deposit minerals, and to determine the paragenetic sequence of the galena deposits in the study area. The research methods employed were mineragraphic and X-ray diffraction. Ore minerals in the deposits were identified as galena, pyromorphite, cerussite, and anglesite. The associated minerals are quartz, illite, pyrite, malachite, covellite, and chalcopyrite. The mineral textures observed in samples 1, 2, and 3 include: disseminated, vein/veinlet, fracture-filling, replacement, coating, and cavity-filling textures. The paragenetic stages begin with the early stage, characterized by the formation of quartz as the primary gangue mineral, followed by pyrite and chalcopyrite as primary sulfides during the hypogene stage. The subsequent stage is marked by the formation of galena as a primary sulfide that fills fractures and intergranular spaces, as well as partially replacing the previous sulfides. The final stage is marked by the formation of secondary minerals resulting from supergene enrichment (calcosite/covellite) and oxidation (malachite, anglesite, cerussite, and pyromorphite), which partially replace galena and chalcopyrite through replacement textures and coat the surfaces of the primary minerals (coating).
