Summary:
A method for rapid generation of complex 3D geological models is presented. The method utilizes scaled physical models which are built out of simple materials that provide sufficient density contrast. The model is CAT scanned, assembled into 3D and elastic properties are assigned to each node. Subsequent post and pre-stack numerical simulations allows us then to investigate several issues of high importance to the application of seismic for mineral exploration. Those are: understanding better the response of complex, fractal geology; improve 3D acquisition design by data decimation and imaging analysis; evaluate the effectiveness of various processing algorithms and provide help during the interpretation of real field data. The method proposed will be used to build a catalog of seismic responses over world-known mine sites.
