    Abstract: A novel method of seismic exploration has been developed to resolve confusing and distorted shear wave reflection seismic data which can be obtained in areas having anisotropic formations. In particular, the present method of shear wave seismic exploration comprises imparting first shear wave seismic energy into the earth at selected points with a first source having a first polarization with respect to the line of survey, and recording first signals representative of the earth's response with first geophones having a first polarization with respect to the line of survey. Also, second shear wave energy is imparted into the earth at selected points along the line of survey, with a second shear wave source having a second polarization with respect to the line of survey, and recording second signals representative of the earth's response with second geophones having a second polarization with respect to the line of survey.
