9 km Long P-Wave Reflection Profile Analysis of Lepanto, Arkansas (2006)

This report presents preliminary data from a 9 km long P-wave reflection profile acquired between May 9-19, 2006, near Lepanto, Arkansas. Utilizing a Thumper Minivibe I P-wave source, the data reveals insights into the geological formations along the Mississippi River, specifically in Quaternary, Tertiary, Cretaceous, and Paleozoic strata. With a focus on raw seismic data filtered for specific frequency ranges, this study contributes to understanding subsurface conditions and geological evolution in the region. The processing involved includes AGC, BP filtering, and vertical exaggeration for clearer visualization.
