Summary
As mineral exploration seeks deeper targets and targets under cover, the need for low cost and low impact subsurface imaging is increasingly important. A recent addition to the toolbox of geophysical methods is ambient noise surface wave tomography (ANSWT) which produces an S-wave velocity image of the subsurface using naturally occurring seismic signals from waves, oceans, trains, etc. - no active controlled seismic sources required. In this presentation, we provide a brief introduction of the ANSWT method and review two recent projects: Marathon Phase III and Schumann Lake, both projects located in Ontario, Canada.
