N2  - Rambatan Formation in the western part of North Serayu Basin, Brebes, Central Java, comprises generally
flysch facies of turbidite sediments deposited in a deep marine environment. This formation is equivalent to Merawu
Formation found in the eastern part of the basin and deposited in the environment of tidal flat to subtidal. The turbidite
sediments were highly controlled by a rapid downward movement taking place continuously during Early to Late
Miocene. The variation of the depositional environment has been the object of this research which aims to understand
the sedimentation process of Rambatan Formation in this type locality with a modern turbidite approach. Rambatan
Formation was deposited in N13-N19, as a deep marine sediment channel, turbidite, and deep marine tidal zone. The
sedimentation was affected by gravity flow and bottom current. The sediments on N13-N14 were marked by turbidite
sediments until Middle N17. The sediment supply increased on Middle N17, as a sediment filler on a channel marked
by contourite mud layer (muddy slump) and debris flow, with sources from the north. The increase of sediment supply
was followed by an environmental transformation from a deep marine channel into deep marine tidal area. In N19,
the sediments were redeposited as turbidite sediment, starting with debris flow in Middle N18.
