Abstract
The present invention relates to methods of seismic exploration utilizing vibrationally generated, elliptically polarized shear waves in an earth medium for subsequent detection of one or more dimensions of orthogonal particle motion. The invention relies upon a shear wave source of a type which couples a continually rotating longitudinal force into an earth medium thereby to propagate an elliptically polarized shear wave for refraction, reflection or subsurface detection, various forms of exploration being well within the capabilities.
