Abstract
Kolaka area has quite interesting geological phenomenon by discovered graphite minerals that formed in metamorphic rocks. Graphite is one of the non-metals C carbon allotrope that have conductive properties to electricity and its origin from organic material. Metamorphic rocks of Southeast Sulawesi, precisely in Kolaka has two metamorphic formations with different age in regional geology, they are Mekongga Complex (Carbon) and Pompangeo Complex (Cretaceous-Paleogene). Lithology of the Mekongga Complex consists of dominantly schist (muscovite-quartz-chlorite-graphite), and green schist. Pompangeo Complex composed by phyllite (muscovite-quartz-chlorite-calcite-graphite), green schist, and limestone. Bearer rocks of graphite of research area are graphitic schist in Mekongga Complex and graphitic phyllite in Pompangeo Complex. In this area, magma activity produced intrusion (dyke), that process helped the maturation process of graphite. Petrographic results of these two locations show the presence of graphite with sizes ranging from 0.2-0.8 mm in thin section, graphite was accumulated in foliation of rocks. Graphite characterization was conducted based on characterization of petrographic, LoI, XRD, and EDS-SEM. Keywords: graphite, carbon, Southeast Sulawesi, Pompangeo Complex
