The mapping area is in Banyumas, specifically Gumelar Village and its surroundings, with an area of ±54 km². Mapping includes aspects of geomorphology, stratigraphy, geological structure, geological history and environmental geology. The geomorphological units of the mapping area are based on morphometry and morphogenesis, namely the Fluvial plain geomorphological unit, and the weakly undulating geomorphological unit - Structural hills. Based on the lithotratigraphic division, the research area is divided into two units, namely the Halang carbonate sandstone unit and the Halang carbonate mudstone unit. Rock formation in the mapping area began in the middle Miocene - Pliocene. The structures that develop are antyclinic and synclinic fold structures, the left slip faults and joints. Sources for the research area are geotourism and agricultural land in pine forests, and land movement.
