A bstract Magneto‐telluric radio frequency measurements can be developped in shallow applications in civil engineering, mining exploration hydrogeology and even archeology. In the V.L.F. and L.F. ranges the depths usually encountered range from 4 or 5 meters to nearly 50 meters. Specially designed equipment allows rapid work—in some cases even continuous profiling. Field data obtained over a fault, a cavity, and sedimentary ore deposits agree well with data from conventional electric surveys.
