Pemisahan anomali regional-residual data gayaberat daerah Karangsambung Jawa Tengah menggunakan metode trend surface analysis

Abstrak

Separation of regional-residual anomalies in the gravity method in the Karang Connect area of West Java using the surface analysis trend method. The separation of this area is made using the Matlab program language and then made its appearance in the Surfer software. Qualitative interpretation is done by observing gravity data in the form of Bouguer anomalies. Whereas quantitative interpretation is carried out to understand deeper the results of qualitative interpretation by making a cross section of gravity on the anomaly contour map. Based on the results of spectrum analysis results of screening with a window width of 23x23 km, a regional anomaly map was obtained. Residual anomaly values otained ranged from -45 to 30 mGal which showed a negative to positive anomaly pattern. Negative anomalies are range of -45 to -10 mGal, while positive anomalies are range of 0 to 30 mGal.
