Analysis of mineral sediment characteristics of Bantimurung Bulusaraung National Park in the Karst Maros Region

Abstract

Research has been carried out to describe the profile of the sediment layer and analyze the composition of sediment minerals in the former mine area of the Karst Maros area. Data is collected by measuring in the field in one of the former mining areas using a geoelectric tool. The measured data are current strength, voltage, and then an analysis is performed to obtain the value of resistance and resistance using the Wenner configuration. The results of the analysis were processed using Res2dinV software to obtain resistivity cross-sections in the measurement area. Processing results obtained by sedimentary profiles in the former mine area of the Maros Karst Area in the form of layers at resistivity values in the range of 0.17 Ωm to 7.80 Ωm and the corresponding types of material are groundwater, sand, clay, and limestone. The varying resistivity value is around a depth of up to 6 m. After this depth, the bedding will have almost the same material as hard limestone. While the mineral composition in the Karst Maros Region consists of chalcopyrite, galena, pyrite, pyrrhotite, magnetite, cassiterite, hematite, and clay.
