Abstract :
The Rangkasbitung Basin is part of the Banten basin which is bounded by Tinggian Bayah in the South and Platfom Seribu in the North. The existence of the Bojongmanik Formation as a typical deposit of the Rangkasbitung Basin still has confusion in the nomenclature so that it needs to be studied in depth. The aim of this research is to reveal the geological characteristics of the Rangkasbitung Basin, to distinguish the characteristics of the lithostratigraphy and biostratigraphic of the constituent rocks, also to describe the correlation and study of the sedimentation succession of the Rangkasbitung Basin. The methods are mapping and measuring surface geology and microfossil analysis. The results of the analysis of the distribution of bentonic fossils found paleogeometric shapes showing two geometrical forms of basins and two high geometric shapes in the Rangkasbitung Basin, namely, the Jasinga Basin and the Leuwiliang Basin and the Cigudeg Height and the Muncang Height. The paleogeometric form that occurs is thought to be a control of the faulting block which results in the form of valley and high depression. Based on different lithostratigraphic and biostratigraphic characteristics, the Bojongmanik Formation is separated into two formations referred to as the "Jasinga Formation" and the Bojongmanik Formation. The fossil content of the "Jasinga Formation" has 6 genus 30 plankton species and 21 genus, 11 benthic species. The Bojongmanik Formation has 9 genus, 33 plankton species with 19 genus and 6 benthic species. The presence of “Amphistegina†and “Rotalia becarii†is a parameter for the depositional environment of the Jasinga Basin and the presence of “Spaeroidinella and Spaerodinellopsis†which characterizes the age of the Bojongmanik Formation. The evolution of the Rangkasbitung Basin began in the Early Middle Miocene (N9-N12), filled with the Jasinga Basin by sedimentation of the "Jasinga Formation", the Cigudeg Height is filled by sedimentation of the Bojongmanik Formation which extends to the edges of the Jasinga Basin. In the Late Middle Miocene (N13 - N14) a regression process occurred, resulting in the southern part of the Jasinga Basin becoming land, and the Bojongmanik Formation starting to fill the Leuwiliang Basin simultaneously by sedimentation material of the Cibulakan Formation which was sourced from the Continent Shelf Sedimentation Mandala that covered each other. In the Late Miocene (N15-N17), the Jasinga Basin and the Leuwiliang Basin were lifted to land, in the northern part the deposition of the Bojongmanik Formation still took place in the periphery Neritic environment until the transition. Keywords : Evolution, Rangkasbitung Basin, Middle to Late Miocen
