Abstract
This paper presents a case study of mapping basement structures in the northwestern offshore of Abu Dhabi using high-resolution aeromagnetic data. Lineaments analysis was carried out on the derivatives of the reduced to the pole (RTP) magnetic data, along with supporting information from published geologic data. The lineament analysis suggests three well-defined basement lineaments in the study area, which are mainly trending in the N-S, NE-SW and NW-SE directions.
The RTP magnetic data reveals two high magnetic anomalies related to structurally-controlled highs in the deep seated Arabian Shield. Depth to basement was estimated using spectral analysis and suggests the two basement blocks are in the same average depth level (around 8.5 km).
