Abstract
This paper provides a comparison of vintage, UK national scale aeromagnetic data and modern, high resolution airborne data using a case study across the island of Anglesey, NW Wales. Deeper responses associated with magnetic basement are masked by a near-surface Palaeogene dyke swarm. In order to extract shallow and deeper basement features both data sets are processed in a consistent manner using azimuthal and spectral filtering procedures. A joint assessment is then carried out on the resolution capabilities of both data sets using established edge and depth location methodologies.
