Abstract

The research conducted on the outcrops of Shale and Coal in the Mallawa Formation in South Sulawesi aims to understand the geochemical characteristics of the source rocks and the geological features to determine their depositional environment. Source rocks are sedimentary rocks where hydrocarbons accumulate, typically fine-grained sedimentary rocks. The objective of this study is to analyze the maturity and potential of the parent rocks in the Mallawa Formation, South Sulawesi. The methodology involves field sampling of rock specimens for laboratory analysis, including Total Organic Carbon (TOC), Rock Eval Pyrolysis, %Ro (% Reflectance), GC-GCMS (Gas Chromatography - Gas Chromatography Mass Spectrometry), and fossil analysis. By employing these methods, the research aims to provide insights into the hydrocarbon potential and depositional environment of the source rocks within the Mallawa Formation in South Sulawesi. The findings of this study could serve as a basis for further exploration of natural resources in the region.
