Gravity, magnetic, and electromagnetic methods are primary exploration techniques used in kimberlite exploration to define a kimberlite pipe's location and shape. Sometimes these methods produce nonunique results because of weathering of the upper part of a kimberlite pipe and its considerable inhomogeneity. Complex pipe geometries and associated faulting and fracturing may be very difficult to assess by potential-field methods. Application of seismic methods in kimberlite exploration has been limited.

In sedimentary basins, however, kimberlite pipes are likely to be a suitable target for the application of seismic reflection methods because of the difference in elastic properties between the pipe material...
