Abstract

In the last twenty-five years, there have been significant advances in the spatial resolution of most geophysical sets of data. Whereas geophysical data were once commonly acquired along widely spaced profiles, it is now more usual to obtain geophysical data along numerous closely spaced traverses. As a result, the spatial sampling is now comparable in both horizontal directions and the greater resolution has greatly improved the interpretation of geological features. A major benefit of high resolution geophysical data sets, is the ability to generate pseudo-geological maps. The geological map traditionally has been a one of the most important domains for visually summarizing geological information. The broad objective of this study was to use seismic refraction methods to map in detail a faults zone and shear zone, which there was no evidence of subsurface faults in study area. Seismic refraction methods were selected because of their potential ability to provide greater lateral resolution of the narrow vertical shear zone, than is currently the norm with electrical or electromagnetic methods. The results of the seismic refraction surveys show that the hidden faults occur as a narrow region with low seismic velocities and increased depth of weathering.
