Course Content

As demands for metals increase globally, many national governments have initiated programs toward critical mineral mapping that leverage legacy potential-field data combined with newly acquired data at national to global scales. Potential-field data provide an essential framework for integrated analysis as the gravity and magnetic data are available over reconnaissance to tectonic scales and, importantly, are most often publicly available. Synthesis of multiple geophysical data sets to image the concealed parts of the geology is crucial for a wide range of resource applications that cannot be done using a single geophysical method. They are particularly useful in mineral system studies, and given the recent shifts toward renewable energy, represent crucial data sets for mapping mineral systems that host critical metals — the crucial components for green energy solutions.

The Gravity and Magnetics Committee jointly with the Mining Committee call for papers for a workshop scheduled for two half-days and featuring applications that incorporate potential-field data toward understanding various geologic and mineral systems. We encourage submissions from government, academia, and industry that demonstrate how potential fields are filling the gaps in our knowledge in understanding both commercial and noncommercial geology. Geophysical studies that integrate gravity and magnetics with radiometric, electromagnetic, thermal, and seismic methods from deposit to plate scales are encouraged. This session will have a hybrid structure of oral presentations mixed with posters and will feature several keynote speakers. We invite the community of geophysical service companies, government agencies, industry, and academia, particularly students, to this distinct and engaging session in order to share experience and engender new collaborations.
