Interpretation of 2D seismic profiles in complex geological terrains: Examples from the Flin Flon mining camp, Canada

A methodology was demonstrated for the 3D interpretation of networks of 2D seismic profiles in conjunction with other 3D geological constraints. The methodology employs 3D migration of 2D seismic data as a means of directly correlating reflections with out-of-plane geology, followed by ray-trace modeling of interpreted 3D geological surfaces. The proposed interpretation workflow was demonstrated with examples taken from 2D seismic profiles that were recently acquired for VMS ore exploration within the Flin Flon mining camp, Canada. In each example, the utility of the method was demonstrated and the resulting inferences were validated by comparison with a true 3D seismic survey acquired over a subset of the same area.
