Abstract

The result of gravity measurement in the studied area, which is mainly covered by volcanic rocks, has an anomaly value ranging from -11 to 45 mgal. Quantitative interpretation of Bouguer anomaly and magnet shows a subsurface profile depicting the geological processes and tectonic activities. The qualitative analysis results of residual and Bouguer anomalies indicate faults mainly have east - west and north - south directions. Meanwhile, the quantitative analyses of three subsurface model profiles show the graben structure in the Subah area to the south east of Batang city.
