From the abstract: Crustal structure in southeastern Egypt has been investigated to elucidate the nature of crustal thinning across the northern Red Sea. P-wave receiver function modeling for seven stations in southeastern Egypt yields typical Proterozoic crustal thicknesses of 35 to 38 km around Lake Aswan, and thinner crust (25 to 26 km) within 50 km of the Red Sea coast. Vp/Vs ratios are on average 1.78 and indicate an intermediate composition crust. These results, when combined with other estimates of crustal thickness in the region, reveal a symmetric pattern of crustal thickness benea
