Mineralization of Limestone and Volcanic Rock of the Tacipi Formation

Rocks are a collection of minerals that have frozen. Rocks can contain one or several minerals. Minerals are physically and chemically homogeneous crystalline substances in the earth crust. Minerals are formed at the same time as rocks. Minerals are a type of natural resource that must be studied. However, there have never been any mineral content studies done in the Tacipi Formation area, which has a great natural resource potential. Research conducted in Ulo, Lanca, and Lappae Villages (Tacipi Formation), Bone Regency, Indonesia, aimed to determine the mineral content of the rock, the crystal structure, and the distribution of rock minerals at three sampling points: point 1 (Ulo) with igneous rock samples from Bone Volcano, point 2 (Lanca) with sedimentary rock samples and point 3 (Lappae) with sedimentary rock samples from Bone Limestone tested with X-Ray Diffraction (XRD) analysis. The analysis of all samples using the High Score Plus software obtained mineral content: magnesian calcite, calcite, quartz, diopside, corundum, chalcopyrite, and wustite. The minerals that often appear are magnesian calcite and quartz, with a mineral crystal structure that is rhombohedral and hexagonal with varying sizes. Quartz is produced from interbedded rocks of the Bone volcanic rock with the limestone reefs of the Tacipi Formation. The research results, which have a novelty value, show that the mineral richness in this area is diversified. The research results can be used by the community, local government, and investors to develop the mining sector.
