Bentonite is a phyllosilicate layering mineral that have tremendous psyco-chemical properties making it versatile in industrial application. Bentonite in Indonesia found in widely geological environment, it can be obtained as weathering or devitrification product of volcanic glass, alteration of volcanic rocks, and deposited in many marine sedimentary rocks. Bogor Basin in the western part of Indonesian fulfilled with two Miocene sedimentary deposits containing clay shale that associated with bentonite. The clay shale in the Jatiluhur formation showed dark grey color calcareous clay with shally texture deposited as deep marine sedimentation, meanwhile clay shale of Cantayan Formation showed light grey color tuffaceous clay with massive texture, non-calcareous which related with volcaniclastic deposit. This research was conducted by geological mapping and laboratory analysis (petrography, X-Ray Diffraction, Scanning Electron Microphobe) to characterize shale clay from both Jatiluhur and Canyatan Formations, and also simply laboratory experiment in applying both shale clay as purify material to cooking oil waste. The purpose of the study was to determine the psychochemical of shale clay in Bogor Basin and seeing its potention as purify material of oil waste. The research showed that volcaniclastic clay shale of Cantayan Formation is more effective to purify the oil waste than the marine clay shale from the Jatiluhur Formation. The SEM and XRD analysis suggest the significant occurrence of montmorilonnite in volcaniclastic clayshale of Cantayan Formation that makes it more applicable to purify cooking oil waste
