Aeromagnetics in exploration
Uses for aeromagnetic surveys include the evaluation of prospect leads and prospects that are controlled by basement fault movements. The identification of basement faults is based on the interpretation of the significance of magnetic edges. Magnetic edges are of two general types: 1) contacts between rock types within the basement, and 2) faults on top of the basement. Traditionally, aeromagnetic surveys have undersampled so that magentic-edge interpretations were not practicable. High resolution aero-magnetic surveys are designed so that basement faulting can be identified and interpreted. Interpretations must be made from magnetic records that have been processed adequately. Many of the magnetic edges which are contacts between different basement lithologies are related to the paleostress fields and are caused by shearing. The identification of the components of the shear models help to explain the orientation of magnetic edges and help to identify the types of basement faults that can be expected. The interpretations are used as working hypotheses for establishing prospects and prospect leads in the overlying sediments.
