Sedimentology and Structural Geology of the Neogene Formations, South East Sabah.

Sabah, situated in the northern part of the island of Borneo, and lying adjacent to actively moving plates in South East Asia region has a complex geological history. The well-developed compressive and extensional structures are the manifestation of several regional tectonic events in Sabah since the Early Tertiary. The area of interest in this project is the Neogene formations specifically the Kalabakan and Kapilit formations located in South East of Sabah. The highlights of this study would be on the structural geology and sedimentology of the area.
In structural perspective, the outcome of the project suggested that the Kapilit and Kalabakan area is affected by series of shearing of wrench faults. In addition, by sedimentology point of view, the area has been concluded as from marine origin through extensive interpretation of the formations’ outcrops during the field work. Thin section analysis, rose diagram and lineament analysis through satellite images are lists of methods used in order to understand more on how these Neogene formations was geologically shaped in South East Sabah
