| Abstract | Downhole seismic data were acquired at the Victor kimberlite, in the James Bay Lowlands of Ontario, in order to attempt to produce an image of the pipe at 10 to 300mdepths and, in doing so, to evaluate
the applicability of this method in delineating diamond resources. The survey was designed to allow two different imaging strategies, one using shot points located over the kimberlite pipe and the other using shots over the host sedimentary rocks. It
was hoped that shot points over the kimberlite would directly image the kimberlite-sedimentary rock contact, whereas shots over the nearby (<250 m) sedimentary rocks would indirectly determine the kimberlite margin by mapping truncations of
reflections from the sedimentary layers. Results demonstrate that the indirect mapping approach has potential to define the geometry of the kimberlite at depth. |
