Title: An unique of the late Miocene turbidite succession in Brebes and Banyumas Central Java
Abstract: The late Miocene sediment in the Brebes and Banyumas area has analyzed to identify turbidite facies and reservoir analog. Active hydrocarbon systems are almost indisputable in this basin due to numerous oil seepage. This study primarily focused on their characteristics, distribution patterns, and vertical succession of turbidite deposits. The Measurable stratigraphic detail of 8 sections was carried out in the Ciseureh district Brebes area and Karangpucung district Banyumas area. The lower-upper part of the formation gradationally is generally a siltstone-dominated, interbedded tuffaceous siltstone, tuffaceous sandstone, and carbonate properties. Furthermore, this paper was comparing five deposits classification from Bouma sequence (1962), Mutti and Ricci (1972), Walker (1976), Emiliano Mutti (1999), as well as flysch and mollases. Based on surface field observation we find many sedimentary structures, vary textures, and vertical successions. It can be used parameters to divide four classifications of turbidite deposits, flysch and mollases. This sediment was interpreted as classical turbidite, channeled portion of supra fan-lobe, a smooth to channeled portion of supra fan-lobe on middle-upper, a smooth portion of supra fan-lobe on middle-upper. On the other hand, the turbidity current in the North Serayu and Banyumas Basin caused by the slope of the volcano flank, not the submarine canyon. Based on data obtained, the five turbidite facies models were compared.
