Relationship between physical properties and alteration at the St Ives Gold Mine, Western Australia

Abstract

I use a simple rock physics model, based on linear combinations of the properties of unaltered and altered rocks, to predict the physical properties of altered rocks at the St Ives Gold Mine, Western Australia. Previous studies of mineral systems demonstrate that alteration can produce physical property contrasts with respect to unaltered host rocks and thus produce geophysical signatures in various datasets such as gravity, magnetics and seismic.
