<![CDATA[The Meluhu Formation is an important Mesozoic sedimentary unit in Southeast Sulawesi that records the geological and depositional evolution of the region. However, studies specifically addressing the characteristics of its sandstone remain relatively limited and show variations in lithology, provenance, depositional environment, and age interpretation. This study aims to synthesize the available literature on the lithological, petrographic, provenance, depositional, stratigraphic, and tectonic characteristics of Meluhu Formation sandstone. A systematic literature review was conducted using relevant peer-reviewed articles, conference proceedings, and geological reports. The reviewed studies were selected based on their relevance to the Meluhu Formation and the regional geological framework of Southeast Sulawesi, and the extracted information was synthesized thematically. The results indicate that the sandstones are dominated by quartz and lithic fragments, with variable feldspar contents, and are classified as sublitharenite, lithic arenite, arkose, subarkose, and greywacke. Provenance analysis indicates contributions from recycled orogen, interior craton, and undissected arc provinces, while the depositional environment evolved from fluvial and deltaic settings toward shallow marginal marine conditions. The formation also exhibits a significant age controversy between Triassic and Middle–Late Miocene interpretations. These findings highlight the need for integrated geochronological, sedimentological, petrographic, and diagenetic studies to refine the geological history and reservoir potential of the formation.]]>
