- W2515358049 abstract "Shallow mineral deposits of giant sizes are rapidly mined out and thus to sustain mining and help the economic growth, there is a tendency to explore deeper deposits. Most economic size mineral deposits are hosted within a complex and heterogeneous medium affected by various stages of deformation and metamorphism. Therefore, to understand their seismic responses, 3D heterogeneous modeling of various scale lengths should be considered. Here we present an algorithm that allows to build a model with various degrees of heterogeneity and structural anisotropy for the medium and use that to study a 6 Mt massive sulfide deposit at about 1 km depth. The seismic response was simulated using a 3D acoustic finite-difference method. Wavefield records through the model show imaging of the ore body in the presence of a high-degree of structural anisotropy/heterogeneity is difficult, but the associated amplitude anomaly appeared as diffraction can be detected within the 3D recorded wavefields and likely possible to be imaged using high-fold seismic data. The recorded wavefield however suggests some asymmetric pattern for the diffraction due to the high-degree of structural anisotropy introduced and hence care must be taken when processing and locating these deposits within highly preferentially-oriented heterogeneous medium." @default.
