Abstract

Summary

Large-scale glacial deposits present challenges to seismic earth model building because of their rapidly changing velocities in incised tunnel valleys with glacial- and water-laid fill. We present an approach for detailed geological interpretation of seismic horizons as boundaries for stratigraphic and lithological units using the structurally sharpened continuous colour (SRGB) technique. In the first step, colour-textured time slices reveal geological features contained in the seismic data cube. In the second step, colour-textured horizons are correlated with stratigraphic and depositional information for geological interpretation. The framework of interpreted horizons and seismically derived facies can then be used as a framework for velocity earth modelling. This approach can be used with any type of 3D geophysical data, in both time and depth domains.
