Abstract

Throughout the Khoman Formation near the Farafra Oasis, Egypt, a series of basins called desert eyes are thought to be the result of a system of subsurface polygonal faults. The research area spans four specific locations in which seismic data was gathered using both forward and reverse 2-D refraction surveys. The area of interest consists predominantly of Cretaceous chalk deposits, in which extensive faulting and desert eye structures can be observed on the surface. The research aims at locating faults along with their respective vertical throw, and potentially recognizing desert eye structures in seismic section. Correlation of the subsurface data to visible faults on the surface and understanding seismic refraction techniques will allow accurate identification of desert eye structures that may no longer be visible due to eolian deposition.
