Study area is located in Padabeunghar, West Java. Area is located at 700’00” - 702’26.3” South Latitude and 106043’16.5” - 106045’54.2” West Longitude. Study area is ± 13.5 km2 with altitude 102 m - 628 m above sea level. <br /> <br /> <br /> <br /> <br /> <br /> Geomorphology units in study area consists of Jampang Homoclinal Ridge Unit characterized by a rather steep hill with similar slope direction of rock strata to the Northeast. Bojonglopang Karst Hills Unit characterized by a rather steep to very steep hills, has the morphology of caves and underground rivers. Jampang Synclinal Valley Unit characterized by sloping and rather steep hills surrounded by Homoclinal Ridge . <br /> <br /> <br /> <br /> <br /> <br /> Study area consist of Andesite Breccia – Andesite LavaUnit aged Late Oligocene - Early Miocene and deposited in Marine environment. In Middle Miocene epoch, Limestone Unit was deposite as reef on Andesite Breccia - Andesite Lava Unit with disconformity contact. Limestone Unit was deposited in Middle Neritik environment. In Late Miocene epoch, Sandstone Unit was deposited in Middle to Outer Neritik. In Quaternary Period,QuarterBreccia Unit deposited and disconformity with older unit. Furthermore, Alluvial Sediment Unit deposited at Resen. <br /> <br /> <br /> <br /> <br /> <br /> Geological structures in study area is Cibojong Fault and Padabeunghar Fold. Cibojong Fault is a dextral fault with fault plane orientation N1650E / 740SW. These faults cut Padabeunghar Folds which is a synclinal fold structure with fold axis plane orientation N2790E / 840NE. Padabeunghar Folds estimated occur in Pliocene and Cibojong Faults estimated occur in Quaternary. <br /> <br /> <br /> <br /> <br /> <br /> Diagenesis process that occurs in Limestone Unit aremikritisasi microbial, neomorfisme, dissolution, compaction, dolomititation and cementation. diagenesis environment that interpreted from petrographic observations are consist of marine, mixing zone, meteoric phreatic, burial and meteoric vadose.
