Electromagnetic simulations of borehole radar for metal ore detection

We perform finite difference time domain (FDTD) numerical simulation for metal ore detection by borehole radar. The ore-body model is adopted from a practical Ni-Cu-Pt ore body which is a magmatic deposit located in Sudbury, Canada. We design three boreholes along a cross-section perpendicular to the geological strike of the formation which is composed with overburden, ore zone, iron formation, peridotite, granite-gneiss, and sediments. We analyzed the simulated borehole radar profiles and found that some interfaces could be detected and some could not, also the ore zone is very absorptive to the wave.
