Paleobathymetry study of the Klasafet Formation has been conducted in the Salawati area using outcrop data around its type location in the Klasafet River. Aim of the study is to reconstruct bathymetry (water depth) at the time of its deposition, which is range from Early Miocene to Early Pliocene. The research area is located in the Klamono Area, Klamono District, Sorong Regency, West Papua Province with coordinates of 131°28'37"-131°31'13" East and 01°06'53"-01°09'15" South. Outcrop sample have been collected in five locations namely as DS1, DS2, DS3, DS4, and DS5, with three measured sections have been carried out in DS1, DS2, and DS4. Systematic method of sampling has been applied in those five locations to obtain representative sample from top, middle, and bottom part of the outcrop. Paleobathymetry determination in this study has been taken quantitatively using ratio of planktonic and benthonic foraminifera. The result shows the Klasafet Formation in the research area was deposited in the middle neritic to upper bathyal environment (20-100 m) during Middle Pliocene age, and likely part of the Salawati Basin.
