Globally, deep crustal seismic surveys have been used to investigate crustal architecture, crust- formation mechanisms, and to study mineral system settings. In addition to providing information about the fundamental structure of the crust, there is increasing recognition of the ability of seismic and complimentary deep-penetrating geophysical techniques like magnetotellurics in mapping ‘vertically accretive structures’ exploited by lithospheric-scale mineral systems such as Olympic Dam. These co-located surveys can map both crustal architecture and modification processes particularly important for ore formation, such as zones of fluid/ magma flux, and alteration, and have already been used successfully in the Delamerian Orogen to identify fluid pathways. This article discusses data acquisition and processing, and subsequent interpretation.
