Abstract
Wavelet-based semblance analysis is a relatively new measure which allows for the similarity investigation of local phase relationships between two data sets as a function of frequency (or wavenumber) and time (or distance). The potential for applying this method to geophysical datasets is explored, with quantitative results for two cases. The first case is where two types of data come from the same section of a borehole, and the second case where data comes from similar stratigraphic locations but from different boreholes. Source data comprises density and magnetic susceptibility data from the Bellevue (BV-1) and Moordkopje (MO-1) boreholes located within the Northern Lobe of the Bushveld Complex.
