| Summary: | <p align="justify">Geological mapping were conducted in Buahdua, Buahdua District, Sumedang Regency, West Java. The purpose of the study is to determine the geological order in the area research. Those Geological order are geomorphology, stratigraphy of rock unit, Structure phenomenon that happened and historical geology of this research area. <br />
<br />
Geomorphological units was divided into five units, i.e. Pyroclastic Hills Unit, Cicadas Anticline Hills Unit, Panyindangan Valley unit, The Cilalanang rest of Volcanoes Unit, and Alluvial Plain Unit. Geological history of research area began in Late Micene when deposition of Claystone Unit on Middle Neritic until Upper Bathyal, then on Early Pliocene, Claystone-Sandstone Unit was deposited on Inner Neritic, followed with the deposition of Sandstone-Conglomerate Unit in fluviatil. And then , followed with the deposition of Tufan Claystone. After that, research area experienced a phase of compressional deformation regime trending NNE-SSW causes geological structures, i.e. <br />
<br />
Cicadas Anticline, Cigalagah Sincline, Cikandung Thrust Fault, and Cigalagah Strike-Slip Fault. In those time, there was erosion and then Pyroclastic Breccia Unit was <br />
<br />
deposited by volcanic activities. Exogenous forces such as weathering, erosion, and deposition of Alluvial Unit are deposited until now. <p align="justify"> |
