Surface Wave Attributes for the Mapping of Geo-Structural Features in Mineral Exploration

Abstract

Summary We applied four surface wave attributes (i.e., energy, autospectrum, energy decay exponent and attenuation coefficient) to map the presence of geo-structural features at South Deep Gold Mine (Gold Fields Group) in Westonaria (South Africa). We tested the SW attributes along active seismic lines with a standard multifold approach, identifying the main fault systems of the site. We then demonstrated their effectiveness in detecting coherent geo-structural features also on 3D data acquisitions, as well as on passive data.
