Risk, G.F. 1973 An assessment of the usefulness of geophysical methods in prospecting for scheelite. [s.l.]: [s.n.]. Report / Geophysics Division 77 43 p.
Abstract: This work demonstrates that for some types of scheelite lodes it should be possible to locate new lodes or trace the extensions of known lodes by using geophysical methods based on measuring magnetism or seismic velocity. Of the methods tested, only the gravity method is likely to be useful for locating scheelite alone. However, because the background noise level is relatively high, only very large deposits would be detectable. It seems unlikely that any of the other methods tested (resistivity, self potential, induced polarisation, seismic reflection, seismic refraction) will prove to be useful for finding scheelite.(auth)
