The research area is located in Jampang Tengah area and surroundings, Jampang Tengah Subdistrict, Sukabumi District, West Java. Geographically, it is located in Datum WGS 84, Zone -48, coordinate 694000-699000 and 9218000- <br /> <br /> <br /> <br /> 9223000 and 25 km2 (5x5km) area. The research area is divided into three geomorphology units, those are Anticline Hills Unit, Sincline Valley Unit and Alluvial Unit. Based on lithology characteristic, the research area divided into five unofficial rick units, from the oldest to the youngest those are Tuff Unit, Breccia Unit, Limestone A Unit, Limestone B Unit, and Alluvial Unit. Tuff Unit and Breccia <br /> <br /> <br /> <br /> Unit are equal to Jampang Formation that is Early Miocene volcanism deposits, whereas Limestone A Unit and Limestone B Unit are equal to Bojonglopang Formation that is reefal limestone and bioclastic limestone. At The Early Miocene, Tuff Unit was deposited by gravity mass flow mechanism of pyroclastic of volcanism activity in marine environment. After that Breccia Unit was deposited also by gravity mass flow mechanism in marine environment. Volcanism activity was reduced or might be end marked by deposited Limestone Unit A which was foraminiferous limestone before the Limestone Unit B which was reefal limestone, those marked as relative sea level drop. After that, there was active tectonics that made structural geology as tilt bedding, folding, and faulting which were summarized in oblique tear fault system. Erosion proccess still running and the alluvial deposit still deposited up to recent.
