Abstract
Interpretation of magnetic field data is complicated by the presence of remanent magnetization and benefits from palaeomagnetic and rock magnetic studies. Additionally, the planning of palaeomagnetic sampling sites and mapping of the distribution of magnetizations recovered in palaeomagnetic studies benefits from inspection of magnetic field imagery. These inter-relationships between magnetic field interpretation and palaeomagnetic studies are particularly important in Australia, where deep weathering and extensive cover by younger formations commonly lead to the magnetic field data being the most complete and detailed source of information for basement-related geological mapping and mineral exploration, and where there are few opportunities for direct palaeomagnetic sampling. For the assistance of both magnetic field interpreters and palaeomagnetists, we have developed a database tool to document and interrogate this relationship. We have started to populate the database, and are planning the facilities required to make the database available as an interactive, web-based resource. The key objectives are to facilitate interpretation of magnetic field data, increase reliability in developing deep drilling targets from magnetic field interpretation, and to better establish the spatial range of magnetizations related to igneous, metamorphic, thermal, alteration and mineralization events. Our intention is to establish a widely used, interactive, minimally-moderated resource rather than a more definitive but possibly less useful one. We envisage that the data base will grow primarily through public contributions, and will also be the forum for debate and speculation regarding Australian magnetization events. We believe that this model is appropriate for wider, global application.
