Abstract

Circular and elongate structural basins and domes known as “Desert Eyes” and their associated faults are prominent bedrock features of the Western Desert of Egypt. This study reports preliminary results of a high-resolution magnetic survey of the El Kasr structure, a well exposed Desert Eye southwest of Aswan, Egypt. Magnetic surveys were conducted with an east-west azimuth to constrain the subsurface geometry of possible faults. The absolute regional variation in the geomagnetic field is a sparse 40 nT even though survey lines cross distinct formation contacts. Slight along strike variations in the induced magnetism are detected as the surveys progress northward, parallel to the structure. However, there is little evidence in the pre-processed data to suggest any significant north-south trending subsurface structures. Forward modeling of the data provides better constraints on the subsurface geometry of the El Kasr Desert Eye structure and its potential relationship to local faults.

Biography

Cory is a graduating senior in Geology and Geophysics with an Associate’s Degree in Pre-Engineering. He possesses coursework in both applied and theoretical geophysics, has a working knowledge of multiple software platforms concerned with a diverse range of uses (namely seismic interpretation, statistical analysis, and design and documentation), and has field experience with both seismic and magnetic methods. He has been awarded both the Sheldon Kerry Grant Award for Outstanding Field Work and the Clifford Bishop Memorial Scholarship for Outstanding Geophysics Students, and is a member of the American Geophysical Union as well as multiple honor societies: Sigma Gamma Epsilon for Earth Sciences, Kappa Mu Epsilon for Mathematics, and Phi Kappa Phi. His interests are chiefly affiliated with predictability and statistical analysis of seismic phenomenon, and intends on pursuing a doctoral degree in Theoretical Seismology with advisors Dr. Stephen Gao and Dr. Kelly Liu at Missouri S&T beginning in the Fall of 2012.
