Seismic signature of gold mineralisation from rock physics, petrology characterisation and seismic modelling

Abstract

To better understand the seismic response of lode gold deposits, we characterized in the laboratory over 140 core samples representing different lithologies from two gold mines located in Western Australia. These petrophysical and petrological data, along with a 2D geologic model of the mines, were used as input for rock physics and forward seismic modelling. The results indicate that the texture of the host rocks is the primary control of seismic reflectivity
