<p align="justify">Research was held in Baito and surrounding area, Wolasi Sub-District, South Konawe <br /> District, Southeast Celebes Province in an area of 110 km2. The purpose of this geological mapping is to study the geological setting in research area that includes geomorphology, stratigraphy, structure, and geological history. Primary data used in this research obtained <br /> from field observation and field data collection. Several analysis have been used in order to achieve the objective which are geomorphology analysis, petrography analysis, <br /> micropaleontology analysis, and structural analysis. <br /> Reasearch area landscape is closely related to lithology and geological structures. As a result, research area was divided into three geomorphologic units which are Baito Aluvial Unit, Landono Homoklin Ridge Unit, and Boro-Boro Fault Zone Hills Unit. Geomorphic stage of the research area is mature stage and the drainage pattern are rectangular and dendritic pattern. The oldest rock unit in the research area is Triassic to Jurassic phyllite unit which is part of Australian Continent. This unit can be equated with Meluhu Formation. In the Jurassic up to <br /> the Oligocene, rift-drift phase occured and led to conditions like nowadays continental fragments. In the Early Miocene, there was a collision between Buton Microcontinent and Southeast Celebes Microcontinent. This process caused the formation of imbricate structure in the form of reverse fault and basin. Furthermore, conglomerate-sandstone unit deposited with unconformity contact above phyllite unit in Middle Miocene. This unit is a part of <br /> Langkowala Formation. In the Late Miocene to the Early Pliocene, claystone unit and sandstone unit was deposited. These three units can be synchronized to Boepinang Formation. Then, Aluvial Unit was deposited above previous units. Geological structures developed in the research area are imbricated fault and strike-slip fault. The faults were created due to compression tectonic phase with Northeast-Southwest trend caused by collision between Southeast Celebes Continental Fragment-Buton Continental <br /> Fragment-Tukang Besi Continental Fragment.<p align="justify">
