High-resolution S-wave seismic profiling was used to improve the resolution of mapping of the quaternary sediments within the Ticona Channel, Illinois. Seismic data was acquired using a 12-channel land-streamer with an array, of two opposite directed 14 Hz geophones per channel, mounted on metal sleds. A 1 kg sledge hammer striking a steel-capped wooden plate weighted by a truck was used to generate horizontal energy. Three profiles 1.5 – 2 miles each of S-wave data was acquired across the Ticona Channel. Data was processed using WinSeis Turbo (KGS) and software of Dr. Andre Pugin(ISGS). Raw data was merged, sorted, filtered and stacked; after velocity analysis NMO correction was applied. Output file was converted to SEG-Y format and imported into Kingdom Suite+ software. This software was used to create cultural map, download topographical map and navigate the seismic survey. We picked horizons and converted time horizons to depth. Contouring the depth map was the last applied function. The results will be use to determine the potential and characteristics of the studied sediments as an aquifer. S-wave profiling allowed us to subdivide quaternary sediments within the Ticona Channel and used to improve resolution of the geological mapping.
