The Bayah, Walat and Ciletuh Formations are Early Tertiary quartz-rich sequences in the Southwest Java Basin, Indonesia, which are individually exposed at different localities. The basin is situated in the fore-arc region of the present Sunda Arc system. A detailed evaluation of these formations is based on sedimentological, petrological and palaeontological approaches. It includes the evaluation of depositional environment, composition and provenance. The main objective of this research is to generate a more comprehensive palaeogeographic model and tectonic setting for the fore-arc during the deposition of each formation. It also includes the evaluation of coal seams, source rock potential and reservoir characteristics of some intervals in the studied formations.
