Abstract
While aeromagnetic surveys have been mainly used in the past for mapping depth to magnetic basement of sedimentary basins and for delineating igneous units within the sedimentary section, the advent of high-resolution surveys flown close to the ground with close line spacing has revealed the existence of significant magnetic anomalies arising from sedimentary layers and their structure. As a result of these developments, aeromagnetic surveys now have greater relevance to sedimentary basin studies. The aim of this paper is to explain the types of aeromagnetic responses that arise from the various geological features associated with sedimentary basins and how these responses can be interpreted in the context of basin studies. The discussion is directed to petroleum exploration, but features relevant to mineral exploration are mentioned and, in any case, the generalities presented apply to virtually any study of sedimentary basins.
