Geomorphology of the study area visible from the valley and hills alignment patterns which are controlled by the its structure and lithology. Based on the formation and its geological conditions (Lobeck, 1939), the geomorphology of study area are grouped into four units, namely: Volcanic Hills Unit, Folded Hills Unit, Volcanic Valley Unit, and Alluvial Valley Unit. The stratigraphy of study area was divided into six rock units, which are: Claystone Unit (Menuran Formation), a mixture of proximal to distal turbidites environments products consisting intercalation of sandstone and mudstone, Limestone Unit (Pacalan Member, Menuran Formation) which is a deep-sea turbidite consists of calcarenite and bioclasts with abundant volcanic lithic fragments, Sandstone Units (Formation Leprak), a middle section submarine fan turbidites consisting of sandstones containing volcanic material that is high enough in the form of tuff, breccia units (Formation Ringgit) which composed of volcanic breccia with inset coral limestone in the middle as a marker of shallow marine environments as well as markers on the Pleistocene sea level fall, Tuffaceous Breccia Unit (Bagor Formation) which is a terigenous sediment with dominant fragment particularly of pumice and volcanic glass, and the Alluvial Unit. Based on observation, geological structure of the study area consists of two dominant patterns which are formed in two phases, namely the fold lines Anticline and Syncline Klabang trending northeast-southwest, Menuran Normal Fault with a relatively similar stance, as well as Kali Bluncong Strike-slip Fault relative to the direction of the southwest- southeast.
