【 摘 要 】

Kuningan district is located in the eastern part of west java province. It has uniquely geological feature. In the western part of this district is dominated by volcanic products from the eruption of mount ciremai, while in the eastern part it is dominated by tertiary rocks formation. Geophysical investigations have been conducted to identify subsurface phenomena in eastern part of Kuningan i.e. Lebakwangi sub-district. The results showed that the fault zone has a magnetic anomaly value and bouguer anomalies are inversely proportional, the higher the magnetic value the lower the bouguer anomaly value. faults have a tendency towards the northwest - southeast. The study area tends to be covered by the young volcanic deposits of mount ciremai eruption that overlay the tertiary rocks beneath it so that the existence of the faults tends to be disguised. The inverse geophysical data has an impact on the interpretation of the existing fault structure at the study area where the hangging wall footwall tend to be disguised. Need further geological and geophysical research to further identify the presence of faults in this study area.
