Abstract

Regionally, tectonics of the Medan Quadrangle is occupied by mountainous and back-arc basin zones. Mountainous zone occupies the southwestern of the quadrangles, and is situated in the northwestern part of Kabanjahe, having Bouguer anomaly ranges from -70 to 0 mgals. Zone of back-arc basin occupying more than 50% of the area extends to the east into the Malacca Strait, having Bouguer anomaly ranges from 0 until +20 mgals. The qualitative and quantitative of Bouguer and residual anomalies represent numerous shapes of anticlinal and synclinal structure including faulting system having direction of northwest - southeast.
